COMPARATIVE IMPLEMENTATION ASSESSMENT OF THE AFFORESTATION MEASURE 221 pag. 3-8
Gabriela ALPOIM, C. SĂLĂȘANSustainable planning and management of forest resources is today a common objective across the European Union, as a way of ensuring sustainable management of natural resources, combating climate change and promoting the economic and social development of rural areas. In this sense, the European Union, through the European Agricultural Fund for Rural Development (EAFRD), established in its regulation several articles with a view to the development of space and forest resources in the EU. Namely investments in the development of forest areas and in improving the viability of forests, afforestation and creation of wooded areas, implantation and regeneration / renovation of agroforestry systems, prevention and repair of damage caused to forests by forest fires, natural disasters and catastrophic events, as well as such as investments to improve the resilience and environmental value of forest ecosystems, investments in forest technologies and in the transformation, mobilization and commercialization of forest products, and the creation of producer groups and organizations. In this way, standards and measures that meet these objectives are included in the various National Rural Development Programs, among which the 221 - First afforestation of agricultural land, a measure aimed at the afforestation of land for carbon sequestration, preventing soil erosion and other risks such as flooding and increasing the production of a renewable energy source. The main objective of this work is to make a comparative analysis of the measures taken under the norm 221, common to the National Rural Development Programs 2007-2013 of two member states: Portugal and Romania, through the results obtained at the end of the program, contained in the PRODER 2013 execution report and Final report of the ex-post evaluation of the rural development program for the continent 2007-2013 in the case of Portugal and in the Ex-post evaluation study of the national rural development program 2007-2013 and in the National Rural Development Program 2007-2013 in the case of Romania.

DownloadRESEARCH ON THE INFLUENCE OF NITROGEN DOSES AND VARIETY ON THE PRODUCTION OF SPRING TWO-ROWED BARLEY (CONV. HORDEUM DISTICHUM) IN THE WESTERN PART OF THE COUNTRY pag. 9-14
P. BLAGA, M. PÎRV, Ș. L. BĂTRÎNA, L. BOTOȘ, R. PAȘCALAUObtaining quality and economically motivated productions represents a desire that all farmers follow, and in the conditions of two-rowed barley culture, mineral fertilization often prevents them in its achievement. Taking into account the influence of fertilizers over the quality of the harvest, fertilization should be differentiated according to the purpose for which the culture is intended, feed or malt for brewing. In order to accomplish the theme entitled " Research on the influence of nitrogen doses and variety on the production of spring two-rowed barley (conv. Hordeum distichum) in the Western part of the country" research have been carried out on the territory of the Didactic Station of the Banat’s University of Agricultural Sciences and Veterinary Medicine “King Michael I of Romania” from Timisoara. The main objective of the research was to bring a contribution in determining the influence of doses and of the variety on production, leading to the achievement of economically efficient harvests with superior quality attributes. The effect of nitrogen doses, and of the variety on spring two-rowed barley, has been tested in a bifactorial experience, located on a cambic chernozem soil, phreatic moist. The results point out that nitrogen fertilization has influenced production, the highest value of 2733 kg/ha was obtained by the N100fertilization variant, with a production increase of 8 % compared to the control variant N40 (2532 kg/ha), and a harvest difference of 201 kg/ha, statistically ensured as a significant. By increasing the nitrogen dose from N40 to N80 production increased by 7%, with a significant harvest difference between the two variants of 196 kg/ha. Regarding the protein content, its lowest value was obtained in the fertilization variant N40, in the Kompact variety (10.68%), followed by the Cristalia variety (11.07 %) and the Annabell variety (11.39 %). The results obtained add originality in terms of fertilization and adaptability of some varieties of spring two-rowed barley, representing a viable source of information for spring two-rowed barley growers, who want to obtain high production, but also qualitative ones.

DownloadOVERVIEW OF USING LIVING AND NON-LIVING MICROORGANISMS FOR THE REMOVAL OF HEAVY METALS FROM WASTEWATERS pag. 22-31
Cătălina Filote, Mihaela Roșca, Raluca-Maria HlihorHeavy metal pollution is a very serious threat to the natural environment and human health due to the fact that it cannot be remediated through chemical or biological processes. Although these persistent pollutants are harmful even in small concentrations, the problem becomes critical due to the significant issue posed by the bioaccumulation of these pollutants in various living organisms. Furthermore, the industries that generate large quantities of wastewaters containing heavy metals are in an increasing development. Sources of large fluxes of heavy metal wastewaters include electrical and electronic waste recycling, mining, electroplating and batteries, pesticides, pigments, dyes and textiles production. Hence, viable, environmentally-friendly, low-cost and efficient solutions are required in order to address this problem. Biomass-based removal methods represent a promising alternative to the conventional ones. The capacity of many biological materials for heavy metals removal from aqueous systems has been analyzed so far owing to the very good preliminary results obtained in related research studies. Microorganisms are very potent in this regard owing to their cells being highly adaptable to toxic environments. They have chemical structures with affinity to metals and the capacity to transform very toxic metal species into less harmful ones. The main processes that can be applied in wastewater treatment through the use of microbial organisms are biosorption for inactivated forms, bioaccumulation, biotransformation and biomineralization, respectively, for living forms. For these processes to be used successfully, different parameters such as pH, temperature, metal concentration and dosage of microbial biomass have been studied. The current paper gives an overview of the obtained lab-scale results of heavy metals removal from wastewater using both living and non-living microorganisms. Findings regarding process optimization and upscaling potential are presented. Different microorganisms are considered and compared. Advantages and disadvantages from technical, economic and environmental perspectives are presented. The main current issues and potential solutions are highlighted.

DownloadMETHODS FOR GENERATING THE DIGITAL TERRAIN MODEL, DIGITAL SURFACE MODEL AND ORTHOMOSAIC USING UAV AND GNSS TECHNOLOGY pag. 32-42
Bianca GHERGA1, Ovidiu TIMBOTA, Radu BERTICI, George POPESCU, Mihai Valentin HERBEIThe purpose of this article is to accomplish a Digital Terrain Model, Digital Surface Model and an orthophotoplan - orthomosaic of an area within the Didactic and Experimental Resort of BUASVM Timisoara based on geomatic technologies. The interest for UAVs has been constantly growing, researchers and developers use a lot of resources and efforts to contribute to this topic, especially in applications of geomatics in various fields such as: agricultural and forestry, autonomous surveillance (Herbei and Sala, 2020), emergency and disaster management, traffic management and 3D mapping with photogrammetry. This increase is mainly due to the fact that UAV systems are a reliable and low-cost alternative, fast speed, high maneuverability and high security for image collection. A DJI Phantom 4 drone was used in this work. Phantom IV is a system composed of a drone (UAV) and a mobile RTK station and is suitable for aerial photography and aerial filming activities suitable for data processing in order to obtain orthophotoplanes, point clouds or 3D modeling. Most drones have built-in GPS, IMU (inertial measurement unit) and barometric altimeter, to help navigation. The default positional accuracy is generally good enough for many GIS applications. For example, the DJI Phantom 3 Pro has a position accuracy of ± 1m. If necessary, you can improve position accuracy using ground control points (GCPs), see Ground control points. Ground control points (GCPs) are used in image processing to improve the positional accuracy of data. GCPs are physical locations marked with a fixed position, the coordinates of which have been accurately determined (for example, using a combination of navigation systems, such as GPS and GLONASS, or by using differential GPS). In order to purchase images from the field with UAV technology, the Pix4D application and a mobile tool with Android OS were used, which allowed the realization of the flight plan to acquire the images from the desired location.

DownloadPRELIMINARY STUDIES ON OBTAINING MICROORGANISMS BENEFICIAL TO PLANT DEVELOPMENT AND PROTECTION pag. 43-52
Anton GHIGA, Irina GREBENISANRhizoctonia solani is one of the phytopathogens that attack tomatoes cultivated under greenhouse conditions, causing root and crown rot. R. solani is controlled using methyl bromide, a fumigant known for its high toxicity and its degradative effect on the ozone layer. Fungi of the genus Trichoderma are important biocontrol agents (BCAs) of several soil borne phytopathogens. Trichoderma use different mechanisms for the control of phytopathogens which include mycoparasitism, competition for space and nutrients, secretion of antibiotics and fungal cell wall degrading. In addition, Trichoderma could have a stimulatory effect on plant growth as a result of modification of soil conditions. The biocontrol by fungal species of the Trichoderma genre, of root and crown rot caused by R. solani, are being used as an alternative to chemical fungicides. Phytopathogenic fungi produce significant crop losses annually and to limit their degree of attack we opted for biological control. Although the biological control of plants has been approached by many researchers from different countries, it is important to discover new wild strains native to Romania to combat phytopathogenic fungi and to stimulate plant growth and development. The new wild strains of microorganisms - bacteria and fungi isolated in this experiment have proven their ability to stimulate plant development and combat phytopathogenic fungi that cause seedlings to fall on tomatoes. In vitro experiments were carried out at the laboratory of Ecology and Microbiology at the Faculty of Land Reclamation and Environmental Engineering, U.S.A.M.V. Bucharest starting with March 2020 after soil sampling in Băneasa Forest. In vivo experiments were carried out in a vegetable garden in the village of Tamași, Corbeanca commune, Ilfov county since April 2020. The aim of the experiments was to obtaining microorganisms beneficial to plant development and protection and to highlight the capacity of microorganisms - bacteria and fungi - from forest soil to control phytopathogenic fungus in the complex, causing plant drop at tomatoes, which are frequently occurring in greenhouses and fields. Our research will continue in the direction of rigorous characterization of new wild strains of microorganisms isolated both at the genetic molecular level and of the mechanisms of action in the relationships of plant microorganisms and bioactive compounds secreted by these wild strains of microorganisms. Also, after characterizing the new microbial strains, we aim to obtain on their basis at laboratory and pilot scale growth stimulators and fungicides. For this we will carry out studies to optimize the conditions for growing microbial biomass, to obtain biologically active substances and to formulate ecological fungicides and growth stimulants for plants.

DownloadUSE OF REMOTE SENSING IMAGES IN CROP MONITORING CASE STUDY: SOYBEAN CROP pag. 53-61
S. LANGHE, M. V. HERBEI, F. SALAThe study used remote sensing images in order to analyze and describe the monitoring process for soybean crop. Soybean, which has been the subject of this study, is a culture of particular economic importance due to its many uses. It is used in human nutrition, in the production of animal feed, but also as a raw material for some industries Worldwide in the production of soybean vegetable oil is the second largest after the palm. The satellite images were achieved by the PlanetScope satellite system, images in 4 spectral bands: RED, GREEN, BLUE and NIR, with a 3 m spatial resolution, that show the dynamics of this crop over the period analyzed. The study was carried out over a total time interval (T) of 121 days, from 27.03.2020 to 24.07.2020. The parcel analyzed in this research is part of Experimental Didactic Station of BUASVM Timisoara and it is located in Timis County and it has approx. 55 hectares. Eight satellite scenes were taken over and processed for the 2 combination of spectral bands: Red Green Blue and Near Infrared Red Green and for the calculation and interpretation of 2 useful vegetation indices in such monitoring, namely, the Normalized Difference Vegetation Index (NDVI) and The modified soil-adjusted vegetation index (MSAVI2). Processing of the acquired images was performed with specialized software: ERDAS Image 2014 and ArcGIS v. 10.3, and mathematical processing was done with the Past software. The variation of NDVI index in relation to time, over the study period, a 3rd degree polynomial equation, under statistical safety, R2=0.966, p=0.00208. The NDVI index variation in relation with MSAVI2 has been described by a 2nd degree polynomial equation under statistical security conditions, R2=0.999, p<0.001. Cluster analysis led to grouping of variants according to time of remote sensing (D) acquisition based on affinity under high statistical accuracy (Coph.corr. = 0,955).

DownloadIDENTIFICATION AND ANALYSIS BY GRADIENT OF GRASSLANDS FROM THE ALMĂJULUI MOUNTAINS pag. 62-70
Margareta MĂGUREANU , Loredana COPĂCEAN, Luminiţa COJOCARIUIn Banat Montains, the grasslands have a significant influence, on the one hand by the size of the surfaces and implicitly the weight in the structure of the land fund, and on the other hand, by the role they have in the regional economy. Through classical working methods, locating and mapping grassland areas is a complicated process, requiring very large human and time resources, but supplemented by geomatic methods, which offers the possibility of a computerized and "remote" territorial analysis using geospatial data, simplifies this process and further provides significantly superior results. In this context, the purpose of this study can be divided into two research directions: on the one hand, the identification and location of grasslands areas in the Almajului Mountains, and on the other hand, their analysis on the altitudinal gradient, with direct and indirect implications on genesis and evolution of grassland areas. To achieve the objectives of the study, techniques and methods specific to the GIS environment and implicitly geospatial data sets were used. The identification and location of the grasslands surfaces was done by processing the Corine Land Cover database, 2018 edition, and the analysis of the relief of the area, by processing the Digital Elevation Model. The analysis of the grasslands on altitudinal gradient resulted from the spatial, statistical “crossings” between the grassland surfaces and the altitude map. The researches showed that the grasslands are distributed in all subzones of the considered area, an area of great physical-geographical complexity, which also determines differentiations in the structure of the vegetal cover and implicitly in the typology of the grasslands. The gradient analysis showed a slightly higher percentage of grasslands in the hill area (approx. 43%), between 301 - 600 m. The use of geomatic techniques in the analysis of pastoral space allowed both the identification and spatial location of grassland areas, as well and their complex analysis in correlation with relief factors. Therefore, the approach of the grasslands through the GIS technique allows the analysis of discrete processes, difficult to quantify by classical methods.

DownloadFORMATION OF PRODUCTIVITY ELEMENTS IN DIOIC HEMP pag. 71-78
Ofelia PANDA1, Alina Laura AGAPIE1, TABĂRĂ Valeriu1, Georgeta POP 2Abstract: the present study aims to evaluate the formation of productivity elements in dioic hemp, under the influence of several factors. In this sense, at ARDS Lovrin a multifactorial experience was established, with the following factors: factor A - agricultural year (2017, 2018, 2019), factor B - variety (Lovrin 110, Silvana, Armanca and line Lv 457/08) and factor C - sowing density (7 plants / m2, 37plants / m2 and 150 plants / m2). The elements studied and presented in this paper are the length of the plant and the length of the inflorescence of hemp plants. Of the three factors studied, the one that very significantly influences both parameters, both the length of the plant and the length of the inflorescence, is the density. As the number of plants per square meter is smaller thus the measured values of the two productivity indicators of hemp cultivation have higher values. The study took place in 2017-2019 in the experimental field of the dioecious hemp breeding laboratory at ARDS Lovrin. The soil on which the experimental field was located is a typical chernozem, with a medium clay structure, specific to the area of influence of the resort. The climate is temperate, with an annual average rainfall of around 520 mm and a multiannual average temperature of 10.70C. Hemp is one of the most important plants that produce fibers of vegetable origin and is one of the many plants that produce textile fibers. With very varied uses in the textile industry and in other industrial branches, hemp stems contain 26-32% fibers. Technological factors are very important and are influenced by climatic conditions. Hemp is sown when in the soil in the morning, at a depth of 5-7 cm, it is recorded 7-8 0C. When sown too early, hemp plants grow unevenly, grow slowly, age and do not recover in the favorable conditions that follow. A very significant positive correlation is established between the two parameters, the value of the correlation coefficient being r = 0.97 ***.

DownloadPRODUCTION RESULTS OF SOME DIOIC HEMP GENOTYPES CULTIVATED IN THE PEDOCLIMATE CONDITIONS FROM ARDS LOVRIN, IN THE PERIOD 2017-2019 pag. 79-86
Ofelia PANDA1, Alina Laura AGAPIE1, TABĂRĂ Valeriu1, Georgeta POP 2hemp has attracted much attention from the market and from researchers due to its multiple uses, therefore, improving the production of hemp fiber through research will help promote the promotion and competitiveness of hemp products. Like a plant with multiple uses, ubiquitous over history and the evolution of mankind, hemp (Cannabis sativa L.) is a source of: fiber, wood and seeds used in the world for a wide range of products. The desire for a diet rich in natural, organic products entails the use of hemp seeds in various foods. Due to their high nutritional value, hemp seeds are consumed as food or feed, but can be processed as oil, grit or hemp flour. The economic importance of hemp for the seed is highlighted by the content of oil (30-32%), protein (20-25%), carbohydrates (20-30%) and a significant intake of insoluble fiber (10-15%) and minerals. The paper presents the study of the crop behavior of four dioic hemp genotypes under the influence of pedoclimatic conditions within ARDS Lovrin, during 2017-2019. The cultivated hemp varieties were: Lovrin-110, Silvana, Armanca and line Lv-457/08. Production results to the four cultivars, registered in the first year of experience under the influence of climatic conditions of 2017, were: 370 kg / ha Lovrin-110 variety, 327 kg / ha Silvana variety, 355 kg / ha Armanca variety and 464 kg / ha at the Lv- line 457/08. In the second experimental year 2018, the production values are higher compared to the previous year, for all varieties, as follows: 634 kg / ha Lovrin-110, 525 kg / ha Silvana, 607 kg / ha Armanca and 549 kg / ha Lv-457/08. Analyzing the three experimental years, we notice that, in 2018, the highest productions were made in all four genotypes, obtaining productions that exceed the average seed production made in the experimental cycle. The climatic conditions were registered at Lovrin Meteorological Station, during 2017-2019.

Ionela TÎRZIU1, A. LĂUTARU1, Andreea Giorgiana RĂBONȚU2, Georgeta Sofia POPESCU1*, Anișoara IENCIU2, D. MANEA2The purpose of the present study is to establish the biochemical content of white and black mulberry fruits grown in the South West and West Region of Romania (Gorj County and Timis County). The mulberry belongs to the Morus genus of the Moraceae family. Knowing the composition of mulberry fruits is an useful task, especially to find new sources of natural antioxidants. Berry fruits are rich source in bioactive compounds with health human body benefits. Mulberries have recently gained an important position in the food industry due to the presence of many bioactive componentsThis study investigated fruit weight, total soluble solids content, total antioxidant capacity (TAC), and total polyphenols content (TPC). In black mulberry fruits (Morus nigra) were observed the highest value of the total antioxidant capacity and total phenolic content. Antioxidant capacity can be an effect of the interaction between the colour and the location (place of origin) of fruits. The total antioxidant capacity (TAC) and the total polyphenols content (TPC) were analysed by using the spectrophotometric method. Total antioxidant capacity was determinated used CUPRAC method. Folin Ciocalteu method was used for determination total polyphenols content.From our study, total soluble solids (TSS) values were of 15 % (Morus nigra) to 21 % (Morus alba), mulberries are a rich source of phenolics, with high levels in Morus nigra (0.78 mM GAE/100 g) and low content in Morus alba (0.165 mM GAE/100 g). Differences from content of phenolic content in the fruits depend on many factors, such as genetic differences, the maturity degree at harvest, and environmental conditions during fruit development.Our results indicate that the studied mulberry fruits are valuable products due to their rich content in different compounds with antioxidant activity. Therefore, these fruits can be useful in a balanced diet. This study also brings many arguments for the use of these fruits as potentially healthy foods and their use in the food and pharmaceutical industry.

DownloadUSING GEOGRAPHICAL SYSTEMS IN ORDER TO ACHIEVE THE URBAN CADASTRE IN THE SUBCETATE NEIGHBORHOOD OF ARAD WITH THE HELP OF MODERN TECHNOLOGIES pag. 93-103
Radu Mita, Mihai Simon, Adrian Smuleac, Mihai Valentin HerbeiStudies shown in this paper were realised in the west side of Romania, on the administrative territory of Arad city, Subcetate neighborhood, with the purpose of making a situation plan of the underground infrastructure. More specifically, of the natural gas distribution network. This distribution network incorporates pipes and connections with medium pressure, tuning stations, pipeline stations and connections, valves on pipes and connections. The purpose of this study is the acquistion of the GIS data from this underground network. To create such a plan, we used the Leica Ultra Utility Detection and Trancing System pipe locator to find the network, GNSS Leica Viva GS14 and GS16 to determine the points marked on the route with the locator device, Leica FlexLine TS06 total station to determine the points found on the aerial connections and counters found on fences and constructions. Finally, for proper time management, we used Leica Pegasus: Backpack, which it’s a mobile mapping system. Concerning the detailed topographic surveys, done in a normal way using GNSS equipment and total stations, the use of Mobile Mapping – LiDAR technology offered a real advantage by reducing work time, investigated area and the complexity of the acquired data because the survey was done with the precision of normal equipment. The pros of using geographic information systems and applying them to all sorts of fields have helped spread this concept. The majority of institutions and companies who work with spatial data have initiated a GIS-type project. The complexity of the underground utility network is constantly growing and obtaining precise information regarding the layout of the underground utilities has never been more important. Once all the data is collected on the field, the next part is using this data to create a plan in AutoCad so the database up-to-date with the postal codes, street names, pipe materials, pipe diameters, burial depth, pressure regime, vertical component, length of the main network and that of the embranchment. Some information waa introduced automatically while some needs to be manually put in.

DownloadMETHODS FOR DIGITALIZING INFORMATION FROM ANALOGIC SUPPORT AND CREATING GIS DATABASES pag. 104-112
Alexandra ROSCA, Ionela JUCA, Ovidiu TIMBOTA, Vladimir BELIN, Radu Bertici, Mihai Valentin HERBEIGIS is an acronym derived from Geographic Information System. A geographic information system (GIS) is a computerized system for capturing, storing, verifying, and displaying data related to positions on the Earth's surface. GIS can display several different types of data on a map, such as streets, buildings, and vegetation. This allows people to see, analyze and understand patterns and relationships more easily. There are two types of information used in a GIS: one graphical (and which can be raster or vector) that indicates the spatial distribution of the studied elements and another in the form of a database to store the attributes associated with these elements. Georeferencing is the process by which a scanned image (map) is aligned to a well-defined coordinate system. From a mathematical point of view, the coordinate system of the scanned map will be translated and / or rotated relative to the coordinate system in which the georeferencing process will be performed. Vector representation (digitization) of a map can seem like a very easy task for an uninitiated person. If the data is to be created in a very precisely defined structure and at the same time very correct from a geometric point of view, the problem is complicated. The result instead will be able to represent a very correct data structure that will be able to become a very solid base for all the types of analyzes that are wanted to be realized in the study area. In this paper was made the georeferencing of a map at a scale of 1: 25.000 with the code L-34-78-B-d based on the Transdat program of ANCPI Romania and ArcGIS v. 10.5. The projection system used was the National Stereographic System 1970. After georeferencing the map, a spatial database was created that includes elements such as point, line and polygon.

DownloadFLOODS AND THEIR EFFECTS ON AGRICULTURAL PRODUCTIVITY pag. 113-122
Nicolae, SÎLI, Izabela – Maria, APOSTU, Florin, FAURRomania is located in a temperate-continental climate zone with a moderate precipitation regime, but in recent years, as a result of climate change, there have been significant deviations from the average annual values of temperature and precipitation compared to the multiannual average values, both in Europe and around the world. Agriculture and agricultural productivity suffer a negative impact generated by climate change and extreme weather phenomena, which is added to the negative influence of the anthropogenic factor that causes the intensification of these phenomena through greenhouse gas emissions, deforestation, land waterproofing as a result of the expansion of residential areas, etc. The consequences of the floods affect the level and variability of agricultural production, affect the management of livestock, as well as the location of production as an agro-climatic zone, registering a transition to higher lands. These effects can jeopardize the supply of food on the internal market in some parts of Europe, also leading to increased price instability and an increased risk to farmer's incomes. At the level of Romania, severe localized phenomena were registered, such as prolonged drought, violent storms, large hailstorms, or extreme precipitation from a quantitative point of view, which led to the occurrence of numerous cases of floods. The succession of mentioned phenomena in recent years has demonstrated the country's vulnerability to extreme conditions. The evolution of the average annual precipitations in Romania in 2018 indicates deviations from the climatological norm in force (multiannual average for the 1981-2010 period) at many meteorological stations in the country. The paper presents a brief synthesis of the precipitation regime in Romania, respectively a case study on the floods produced in 2018 and an analysis of their effects on the agricultural sector from a productive point of view. The work ends with a series of solutions and measures to prevent floods in vulnerable areas.

DownloadCONSIDERATIONS REGARDING THE EVOLUTION OF THE LANDSCAPE IN THE AREA OF THE FORMER BAUXITE QUARRIES FROM OHABA – PONOR pag. 123-132
Nicolae, SÎLI, Elena-Maria, VESA, Florin, FAUR, Izabela-Maria, APOSTUOften the exploitation areas of useful mineral substances through quarry works are compared, in appearance, with selenary landscapes (large areas of land, geologically disturbed, strongly modified physically and morphologically and almost completely devoid of vegetation and fauna). In this paper, a former mining perimeter for the exploitation of bauxite ore was studied. The area of interest is located in Hunedoara county (Ohaba - Ponor locality), more precisely the Comarnic - Poieni mining perimeter. In this case, at the end of productive activities, and for a long time after that, the landscape in the quarry’s area brought more with a martian surface, rather than a selenary one, due to the reddish-brown color of the bauxite ore. Given the fact that, despite the legal regulations, at the end of the extractive activities no ecological reconstruction works were carried out on the perimeter, we set out to analyze how and to what extent nature managed to repair this “wound” in the landscape (otherwise characterized by spectacular landscapes and in fact included in the Grădiștea Muncelului - Cioclovina Natural Park). For this purpose, a series of comparisons were made of some photographic materials made between 1995 and 2004, with some recent ones made by the authors during field visits, between 2017 and 2020, comparisons that highlight the general trends of landscape evolution in the studied area under the exclusive influence of natural factors. Also on the occasion of these documentary visits, there were observed areas where time seemed to stand still, ie areas where nature has not yet managed to repair the damage done by man, but also areas of modeling, through shallow landslides, still active. Also, some considerations were made related to the plant species re-installed spontaneously in the studied area, finally being made a framing of the landscape in accordance with the rules indicated by the literature.

DownloadRESEARCH REGARDING THE INFLUENCE OF BANAT CLIMATE CONDITIONS ON RAPESEED PRODUCTION pag. 133-138
Petrișoara Florentina ȘUVEȚI, Ș. L. BĂTRÎNA*, F. IMBREAThe aim of the research was to establish the sowing period and its influence on the harvest and the optimization of mineral fertilization, under the influence of microclimatic conditions of three villages from Timis county, Romania. The biological material used was the Astronomer rapeseed hybrid, approved for cultivation in our country and which in recent years occupies an important segment of the market due to the increased demand on industrial vegetal oil. The research was being conducted in three different locations: Jebel, Stamora Română and Duboz. The experiences were bifactorial ones, according to the method of subdivided plots, in three repetitions and the results are presented as means. The results show that the level of seed production was influenced to a very large extent by the very low percentage of sprouting time, due to the lack of precipitation and the unevenness of their distribution at the level of the experimental zone. In terms of the period of the beginning of the crop, in all three locations, the highest harvests were obtained in E1 and E2, intervals in which both the percentage at sprouting time and the behavior until the entry into winter were close to optimal. Due to the problems encountered in the establishment of crops, the results regarding the capacity of the hybrid and the influence of the type of fertilizer cannot be considered conclusive and as a result it is necessary to continue the experiments in the following years. The highest harvests were registered at Jebel (3772 ka/ha, established culture in E1) and Duboz (3848 kg/ha, established in E2). Regarding the type of fertilizer used and the influence on production, one may notice that the highest harvest of 4288 kg/ha was recorded by fertilization with Duo MPPA10:24:0 + 0.1Zn + 0.1Br +20 SO3, harvest obtained in the Jebel experimental field.

DownloadPERENNIAL LOLIUM SPECIES AS A GERMOPLASM RESOURCE AND BIODIVERSITY pag. 139-149
Loredana Ramona TOPORAN,Marinel HORABLAGA,Ionel SAMFIRAImproving the tolerance to grazing and drought of temperate perennial ryegrass is also an important component of improvement programs, which are best based on an understanding of the physiology of forage growth and development. It was concluded that the density of the cultivator and buds could be increased for new varieties because some existing varieties probably have too low a density of the sower. The quality of perennial ryegrass in terms of protein intake and utilization can be improved by selection and reproduction. Reproductive techniques are used to produce varieties with desired traits, such as high water-soluble carbohydrate content, crude protein content and digestibility. Controlling the transition from vegetative growth to this reproduction is a fundamental process in the development of plants with considerable potential for practical application. Obtaining high and high quality fodder production on temperate meadows, depends on the species and varieties used, soil fertility, technology used, etc. The quality of perennial ryegrass in terms of protein intake and utilization can be improved through selection and reproduction. One way to improve the use of the fodder plant by reproduction could be by selecting a rapidly degradable fiber that would reduce the shelf life of the rumen and therefore improve the feed intake and nutritional status of the dairy cow with higher production. Identifying and selecting relevant traits is a means of enhancing genetic gain in plant reproduction by selecting positively correlated components with sufficient heredity. As a molecular strategy to accelerate feed plant trait improvement, genomic selection, supported by low-cost single nucleotide polymorphism labeling systems, will replace marker-assisted selection using quantitative trait loci-linked molecular markers (QTLs). It is essential that the yield of perennial ryegrass increases, and it is necessary to double the rate of increase in yield in order to support the world's population, which will be increased by 2050.

DownloadINFLUENCE OF CONSERVATIVE SOIL WORK IN MAIZE: FUEL CONSUMPTION pag. 150-153
TRUȚAN Ilie, DUMA-COPCEA Anișoara, MIHUȚ Casiana, SCEDEI DanielaSoil “conservative work” is a generic expression, which refers to a multitude of methods of work, from direct sowing to the aerating and mobilising the entire soil profile, excluding the turning of furrows and the burning of stubble, allowing the maintenance of plant debris on the surface of the soil or close to the surface of the soil and/or the preserving the soil to reduce erosion and improve soil-water relation. The transition from conventional soil to conservative systems was not simple and it gave rise to a multitude of questions to which relevant, scientifically well-founded rhetoric was required, some of which were obtained through fundamental and applicative research carried out under specific local conditions. The large-area implementation of conservative soil systems is not yet nearly resolved even in countries with very high technological potential and solid specialized knowledge. Conservative agriculture aims to increase agricultural production by optimising the use of agricultural resources contributing to reducing widespread land degradation through integrated management of available soil, water and biological resources combined with extreme raw materials. Soil works primarily result in changes in physical attributes that further influence the chemical and biological properties of the soil. It should be pointed out that the technique and time (period) during which soil works are carried out are subject to plant requirements, the purpose for which it is cultivated, as well as to ecological, climate, soil and relief conditions. The unconventional soil work system includes ways of superficial soil processing, namely: heavy disc harrowing, combined rotary grape work, work with the cultivator and the work with the chisel. Unlike the classical system, only soil works are different, the other technological elements (fertilization, herbicide) remain the same. Vegetable debris that remains on the ground at a share of 15-30% being incorporated into the soil according to the variant used. In 2019, there was a consumption of 105.00 l/ha for the control variant, and for variants with minimum tillage, values between 91.00-99.00 l/ha were recorded.

DownloadSTUDIES ON THE INFLUENCE OF SOIL WORKS IN CLASSICAL SYSTEMS IN MAIZE UNDER THE CONDITIONS OF CHIŞINEU CRIŞ, ARAD COUNTY, ROMANIA pag. 154-157
TRUȚAN Ilie, DUMA-COPCEA Anișoara, MIHUȚ Casiana, SCEDEI DanielaIn all agricultural activities, soil works are, according to classical technology, complex actions involving high energy expenditure making productions profitable conditional on the correct execution and during the optimal period. The influence of minimal work on the modification of the physical attributes of the soil is mainly explained by reducing field traffic, mobilising the soil to a much lesser extent than the classical system, modifying biological activity in the soil as a consequence of the ratio between porous and solid parts, as well as by working during the optimal period of performance. In order to implement, in production, the most efficient soil work and weed control technologies, in order to obtain high productions at the lowest cost, we recommend the following: when growing maize on the territory of Chişineu Criş, Arad County, Romania, account must be taken of the physical and chemical properties of the soil, as well as of climate conditions, with direct reference to temperature and precipitation. In view of the sensitivity of maize to weeding, we recommend choosing herbicides according to the composition of weed species Results require the use of the classic variant of soil work, where the highest productions have been obtained, but do not exclude some variants of minimal works. An important argument in support of the research carried out is the value of the main indicators of economic efficiency, which attest to the profitability of maize crops. When cultivating maize on the territory of Chişineu Criş, account should be taken of the physical and chemical properties of the soil, as well as of climate conditions, with direct reference to temperature and precipitation. In view of the sensitivity of maize when weeding, we recommend choosing herbicides according to the floral composition of weed species. Results require the use of classical tillage, in which the highest productions were obtained, without excluding some variants of minimum tillage.

Vasilica ȚUCU, Magdalena Cristina IMBREA, R. PAȘCALĂU, Ș. L. BĂTRÎNA, L. BOTOȘMedicinal plants are cultivated or spontaneous plant species, and which, under various forms - serve health from the beginning of the world. As the chemical industry develops, some of the popular remedies were given another form, they were modernized. Most of the time the effect of using medicinal plants is slower, requiring longer treatment, but it is less - risky and cheaper. The effect of medicinal plants is more complex, acting on several organs or systems at the same time. Herbs produce fewer and much less side effects. The purpose of the research was to complete the biological material, because in our country since 1973, only the population of De Dobrotesti is zoned. In this respect, a comparative culture was organized in which in addition to the population of De Dobrotesti was used a local population in the area, which we named "De Brosteni" after the name of the village from which it was harvested and a population of the province of De Voivodina, Serbia – Montenegro. The results revealed a good behavior of the experienced populations, both in terms of the height of the plants (in the second year at the first harvest it was between 69 cm in the population of De Brosteni and 75 cm in the population of De Voivodina, and in harvest II between 47 cm (De Brosteni) and 55 cm (De Voivodina), and in the third year between 70 cm and 78 cm at the first harvest and between 42 cm and 51 cm at harvest II, the highest values belonging to the population of De Voivodina, and the smallest population of De Brosteni), the branching degree (oscillated in year II at the first harvest between 8 and 11, and in the second harvest between 5 and 6, and in year III at the first harvest between 6,6 and 7,5 at the first harvest and between 5,1 and 6,1 in the second harvest) and the number of leaves/plant (in year II at harvest I between 105 (De Brosteni) and 141 (De Voivodina), and at the second harvest between 55 and 67 in the same populations, and in the third year, at the first harvest between 111 (De Brosteni) and 137 (De Voivodina), and in the second harvest, in the same populations ranged from 45 to 54).

DownloadLIMITING FACTORS FOR THE PRODUCTIVITY OF AGRARIAN LANDS IN LIPOVA HILLS* pag. 164-171
Alina –Andreea ABRUDAN , D. ŢĂRĂUOur research has its origins in the scientific and practical preoccupations regarding gathering knowledge about determining the risks of the apparition of limiting factors in the land productivity and estimating values for a series of the considered factors: compactness degree, soil reactivity, granular composition, surface and depth humidity. All these factors influence the workability of the land. The importance of this subject comes from the fact that there are close links between the structure of the land fund with its characteristics and the grown species, links that are various and complex. Thus, the properties of the soil can greatly influence the roots, mineral nutrition, the air and water supply needed for all the physiological processes, and the plants themselves will influence directly and indirectly the fertility of the soil and its productivity. Taking into consideration all these aspects, and based upon the research done throughout the PHD course - 28th of September 2015 to the present with the topic RESEARCH ON THE ECO- PEDOLOGY BASES OF LIPOVA HILLS LAND PRODUCTIVITY AND POSSIBLE PRESSURES UPON THEIR QUALITY, this paper presents a few aspects regarding the establishing othe risk of apparition and intensification of limiting factors in fields productivity, characteristics that define land vocation for certain usages or agricultural practices. Through its geographical position, the area known as LIPOVA HILLS, LIPOVA PIEMONTE OR LIPOVA PLATEAU, is situated in the western part of the country, 21°22’30’’ and 22°21’30’’ east longitude and 45°55’ and 46°15’ north latitude, as a transition between Western Carpathians and the lower region of Bega- Timis corridor. Thus, the area has specific characteristics of real interest for scientific research. The research is linked up with the fundamentals of durable agriculture, responding to domestic demands of constituting a scientific database needed for the foundation of technology and management measures of agro-eco systems.

DownloadANALYSIS OF THE VEGETATION OF EX-ARABLE GRASSLAND FROM PANNONIC PLAIN AREA – WESTERN ROMANIA (CASE STUDY) pag. 172-182
Veronica SĂRĂŢEANU1, Otilia COTUNA1,2, Carmen Claudia DURĂU1, D. RECHIȚEAN2The abandonment of the arable land is a common phenomenon in Romania mostly in hill and mountain area, but sometimes is present in lowland area on small patches of land or on fields characterised by features that make their cultivation difficult. The succession of the ex-arable land to grassland is very frequent, but the duration of the process is dependent by many variables. The duration of the succession from abandoned arable land to grassland is important in the ecological restoration of these land surfaces, because in this way these fields can provide again ecological and economical services. The purpose of this research is to evaluate an ex-arable grassland surface uncultivated by 7 years for the assessment of the progress of the vegetation succession. The researches were developed on an ex-arable grassland plot from Sacoșu Turcesc, Timiș County abandoned from cultivation since 2012. The plot is bordered on a side by the road, on other side by railroad and on other side by arable land. The vegetation data were collected in 2018. Vegetation surveys were done using the linear point quadrate method [DAGET & POISSONET, 1971]. There was analysed the considering the following aspects: floristic composition based on the main grassland functional groups (grasses, legumes, forbs, rushes and sedges and shrubs and trees); biodiversity (species richness, Shannon index and Simpson index); ecological spectres (phytogeographical elements, life-forms, and indicator values for light, temperature, moisture, soil pH and nitrogen); and typological classification of the vegetation. The results regarding the floristic composition had evidenced a vegetation cover specific for permanent grassland, the perennial grasses being dominant. The results regarding biodiversity were highlighted high values. The structure of the vegetation by biogeographical elements shows high complexity, but the number and contribution of the adventive species was very low, contrary to our expectations. The vegetation structure by life-forms was from far dominated by the hemicryptophyte species, as is in the case of permanent grasslands. The indicator values for nitrogen suggest the former cultivation of the land due to the presence of some species with high and very high demands for this element, but this situation can be found also in the case of eutrophic and even mesotrophic permanent grasslands. The successful and rapid succession process can be associated with the soil seed-bank and to the vicinity of the vegetation stripes from the edge of the road and railroad.

DownloadVEGETAL EXTRACT FROM SPONTANEOUS ROMANIAN FLORA WITH BIOINSECTICIDAL ACTION pag. 183-188
G. M.Daraban1, M.Badeanu2, L.Rusu3, C.Zaharia1, D. Suteu1*The use of biopesticides in the cultivation and growth of plants is part of the concept of "sustainable agriculture". More and more research shows that an increasing number of essential oils and plant extracts have been tested against a wide range of pests with promising results. Thus, it has been shown that various biologically active compounds from plant sources have high efficacy, multiple mechanisms of action, low toxicity to mammals, which has led to the accelerated growth of interest in using them as biopesticides in a stabilized and easy to handle form. The paper aim is to present the results of the experimental researches regarding the investigation of the effectiveness as bioinsecticidal effect of alcoholic plant extracts from spontaneous flora of Moldavia and Bucovina (Romania) (i.e. Artemisia absinthium; Primula veris; Origanum vulgare; Achilleia millefolium) in the pests control during the seeds storage (insect bean-Acanthoscelides obsoletus). Obtaining of the plant extracts was achieved by two extractive techniques: Maceration (M) and ultrasound assisted extraction (UAE) + Maceration (M). The efficiency of the processes (expressed as the degree of extraction) was investigated considering several physical parameters, such as solid / liquid ratio: 1/10, 1/15 and respectively, 1/20, extraction time: 10 minutes and 15 minutes, temperature: 30°C and 40°C. The extracts obtained are considered environmentally friendly since they do not affect the crop plants, but instead they protect it. The experimental results showed that the most efficient method of obtaining plant extracts with a high content of bioactive substances is the combined method ultrasound assisted extraction (UAE) + Maceration (M). In the case of the control sample, there are no abnormal manifestations, the individuals feed constantly and naturally. Regarding the effectiveness of plants in controlling pests of the species Acanthoscelides obsoletus, the descending order is the following: Origanum vulgare, Artemisia absinthium, followed by Achilleia millefolium and Primula veris, whose efficiency is almost identical.

DownloadSTUDY OF SOME QUALITATIVE PARAMETERS OF HAIRY VETCH WITH CEREALS WINTER CROP MIXTURES CULTIVATED IN THE CONDITIONS OF WESTERN ROMANIA (CASE STUDY) pag. 189-195
D. RECHIŢEAN1, M. N. HORABLAGA1,2, Gabriela GORINOIU1, G. RĂDUCAN1, Veronica SĂRĂŢEANU2, Alina AGAPIE1The use of the annual legumes (vetches)in mixtures with cereals for forage as winter crops is a rational way of using the land surface and to improve the seedbed for the spring cash crop. This forage cropping system is encouraged by the agricultural policies from the E.U. because it contributes to the preservation and improvement of soil fertility. The goal of this work is to assess some forage features of several mixture variants of hairy vetch (Vicia villosa Roth.) and cereals with different participation rates of the legume and cereals. The cereals used in this research were four genotypes of wheat (Alex, Ciprian, Crişana and line 6111), two oat genotypes (Sorin and line 2515), one barley variety (Ametist) and one Triticosecale variety (Haiduc). The researches were developed at the Station of Agricultural Research and Development from Lovrin (Timiș County, Romania) on a chernozem soil. The considered participation rates of the hairy vetch – cereals seed mixtures were 2:1 and 1:2, there being used 16 mixture variants. The forage features analysed were fresh fodder yield, dry matter yield, dry matter content, crude protein yield and crude protein content. The forage obtained in the case of early harvesting of hairy vetch mixtures with triticale have the best results as fresh fodder yield. Grater yields of the hairy vetch mixtures with other cereals can be obtained also by later harvesting compared with triticale mixture, respectively (1-2 weeks). Winter crop forage mixtures of hairy vetch with cereals are a great option for livestock feeding with fresh fodder early in spring. The proportion of vetch and cereal in mixture had a great influence on the dry matter yield and crude protein yield and this can be managed by the farmer according with the nutritional needs of his livestock. The use of annual legumes - cereals mixtures as winter crop has numerous benefits from productive and ecological points of view because they act as a cover crop and after harvesting of the fresh fodder the remains are improving the growing condition for the following crop by increasing of soil N content, organic matter content in soil, porosity, percolation etc.).

DownloadTHE SANITATION ACTIVITY CARRIED OUT BY S.C. RETIM ECOLOGIC SERVICE S.A. IN TIMIŞOARA MUNICIPALITY pag. 196-204
D. BOBOUTANU1, N. BAGHINA1. Maintaining the human-nature balance, simultaneously with economic and social progress, a basic concept of sustainable development, is the solution of the two opposite trends: economic growth and protection of environmental resources. This means eliminating current forms of waste and increasing the quality of the environment. The overall objective of sustainable waste management is to prevent and rationally reduce the potential negative impact on the natural environment. Responsibility for waste management activities rests with their generators in accordance with the "polluter pays" principle or, as the case may be, with producers in accordance with the "producer responsibility" principle. Organizing the activities of collecting, transporting and disposing of municipal waste is one of the obligations of local public administrations. In order to meet the national and european objectives in the field of waste management, it is necessary to involve, practically, the whole society, represented by: central and local public authorities (environment, administration, health, industry, finance); waste generators (individuals and legal entities); local sanitation operators; professional associations and research and development institutes; civil society (consumers of goods, non-governmental organizations, etc.). The greening of localities, generally understood as sanitation activity, aims to achieve and maintain the hygiene of an urban or rural settlement, on which depends largely the quality of life of the population. In accordance with Law no. 139/2002 for the approval of the Government Ordinance no. 87/2001 regarding the public sanitation services of the localities, the sanitation is “a local public service of communal management, organized, coordinated, regulated, led, monitored and controlled by the local public administration authorities”. The attributions of this service have in view: the collection, transport and storage of solid residues, except for toxic, hazardous residues and those with special regime; administration of ecological, compliant landfills, sweeping, washing of public roads, cleaning and transporting snow from public roads and maintaining them in operation during frost or frost. As a result, urban greening is an activity that must contribute to preserving the values of the environment, the health of the population and a civilized living environment. This paper describes the sanitation activity performed by S.C. RETIM Ecologic Service S.A. within the municipality of Timişoara, following the route of waste from collection, transport to recovery or final storage on a compliant landfill. The mechanisms of municipal waste management are presented, together with the methods used by S.C. RETIM Ecologic Service S.A. in order to be able to achieve the concept of "zero waste" in the future.

DownloadTHE ROLE OF NUTRIENTS AND FERTILIZATION OF OLIVE AND POTATO CROPS IN THE REGION OF MESSINIA, GREECE pag. 205-210
Panagiotis KOTTARIDIS, Isidora RADULOVAbstract. Two of the main crops in Greece and the Greek archipelago are olive trees and potatoes. Due to the planting of new high-density farms, the area with olive groves in Greece has increased constantly during the last quarter of the century. The productivity of olive trees depends on the supply of N, K and Ca in particular, but also on the level of supply with P, Mg and trace elements. The potato falls into the group of plants with high requirements for nutrients, due to its high productivity and poorly developed high root system, compared to other crops, with a lower solubilizing power of soil chemicals. This study presents the role of the main nutrients in the nutrition of potatoes and olives, with reference to the varieties grown in the area of Messinia, Greece. From the point of view of the quantity and quality of the harvest, not only the quantity of nutrients is important, but also their ratio. Potatoes and olives were grown in the Messina region of Greece. Messinia borders on Elis to the north, Arcadia to the northeast, and Laconia to the southeast. The Ionian Sea lies to the west, and the Gulf of Messinia to the south.

Mihaela-Loredana GHERASIMESCU1,Ana-Mariana DINCU*2, Florinel IMBREA1The purpose of this study is to objectively analyze the agricultural sector, more precisely the evolution of agricultural holdings in Romania.In 2020, in Romania, there were 2.887 million agricultural holdings using 12.8 million hectares of agricultural land, according to data published by the National Institute of Statistics (INS). Also, within 10 years, the number of agricultural holdings decreased by 972,000, respectively by 25.2%, and the used agricultural area decreased by 543,000 ha, respectively by 4.1%.The decrease in the number of agricultural holdings led to the increase of the average agricultural area per holding by approx. 28% (from 3.45 ha in 2010 to 4.42 ha in 2020). The downward trend in the number of agricultural holdings, especially those of very small sizes, was reflected in the structure of agricultural holdings by reducing the share of holdings with a used agricultural area of less than 0.1 ha from 10.3% in 2010 to 4.3% in 2020 and the increase in the share of those that used areas larger than 10 ha from 2.2% in 2010 to 4.2% in 2020 .In Romania, the number of small farms (under 5 ha) represents over 92% of the total number of agricultural holdings in our country, increasing compared to 2005 and significantly more than the EU average from the last year of the analysis (66.3%). Based on the statistical research undertaken by us, individual agricultural holdings predominate with a share of more than 94%, those with legal personality holding a percentage between 1-6%. It is necessary to improve the competitiveness of holdings, especially those of semi-subsistence, which, through investments, both of the fixed capital type and of the introduction of new technologies and performances, will lead to the transformation of a large number of such farms into economically viable structures.

DownloadINFLUENCE OF MINERAL FERTILIZATION ON SUGAR CORN PRODUCTION pag. 217-222
Claudia Ramona AVRAM,Florinel IMBREAThe culture of sweet corn in recent years shows a growing interest among farmers in Romania, especially those with smaller areas of land, but also those with large areas, due to the increase in consumer demand, the profitability of this type of crop and the the possibility of attracting financing sources from European funds.The purpose of this study is to analyze the impact of mineral fertilization on the production of sweet corn in an assortment of marketed hybrids, in the pedoclimatic conditions of 2020.The biological material used in the study of the influence of mineral fertilization in relation to the pedoclimatic conditions in the researched area and the average of the field, was represented by 4 autochthonous sweet corn hybrids(Estival, Dulcin, Prima and Summer Delight). The research was carried out on the territory of Ramna commune, located in the north-west part of Caraș Severin county,on a eutric-gleic alluvial type soil, moderately glaciated, extremely deep, medium loam/coarse sandy loam, developed on medium (clay) non-carbonate fluvial deposits. Analyzing the production results according to the level of nitrogen fertilization on a constant background of P90K90, we observe that nitrogen fertilizers play a decisive role in achieving the production of sweet corn cobs, a fact that is also due to the short vegetation period and the rhythm intense accumulation of dry matter.
