Microbial communities in agricultural ecosystems are characterized by a strong dynamic and radical change due to technological inputs applied. Corn is cultivated on large areas with high requirements for nutrients and an increased potential for activation of specific microbial groups. The aim of this study was to assess the unilateral and synergic effect of zeolite and mineral fertilizers on the development and transformation of microbial functional groups in the rhizosphere of corn. Physiological profile assessment of microbial communities has been carried out on the basis of substrate induced respiration, monitored over a period of 6 hours of incubation. The amount of CO2 registered in Microresp plates represents the activity of functional groups in decomposition of each type of substrate applied. Characteristic groups of microorganisms in maize rhizosphere are capable of decomposing acids: citric, L-malic, oxalic and I±-Ketoglutaric. These substrates indicate the presence of high concentrations of organic matter in soil and the existence of a biological crust on the surface (citric acid), respectively the existence of powerful processes for the decomposition of organic material by actinomycetes (I±-Ketoglutaric acid). The highest microbial activities were observed in groups of bacteria involved in processes of plant growth promotion and microbial groups with an important role in the processes of denitrification (oxalic acid). For the application of urea a triple value of activity of this type of microflora is observed. Functional groups codominant in soils cultivated with corn are specialized in efficient degradation of organic matter and biological crust, zeolite providing the complex substrate necessary for the development of these microorganisms.

The aim of our study was to follow the influence of the substrate, (single respectively double filter paper), the environment conditions (light, darkness), of the seed’s measure and age, on the beans germination. These aspects were followed because the specialty literature correlates the loss of the germinative capacity with different external and internal factors. Three local varieties: P 1 (Albenghino), P 2 (Cannellini), P 3 (Black Turtle), grown in Maramures County, with undetermined growth and different permeability of the seminal skin, were chosen for the experiment. One hundred seeds of every sort were placed in three replications. The energy and germinative faculty were determined, calculating the average values obtained at the replications. We noted that the P 2 variety had the highest germinative faculty of 83.33% on double layer under light conditions, and the germination of 100% under darkness. The P 1 variety is on the second place. The germinative faculty of the P3 variety is of only 70% on a single substrate and 80% on double layer. The germinative energy and faculty of the seeds provided from 2013 are diminished comparatively with those from 2014. The local population P3 proved to be more influenced by age, with a germinative energy of 30% in 2013 and 60% in 2014. The positive influence of the darkness conditions, both for the seeds provided from 2013 and 2014, was noted.

Image analysis methods were developed and diversified greatly in recent years due to increasing speed and accuracy in providing information regarding land cover and vegetation in urban areas. The aim of this paper is to process satellite images for monitoring agricultural areas. Satellite images used in this study are medium and high resolution images taken from QuickBird and SPOT systems. Based on these images, a supervised classification was performed of a very large area, having as result the land use classes. Supervised classification can be defined as the ability to group the pixels that compose the satellite image, digitally, in accordance with their real significance. Gaussian algorithm of maximum similarity (Maximum likelihood) was used, referred to in the specialty literature as maximum likelihood method or probabilistic classification, and based on the use of probability theory (function Gaussian) to compare the spectral values of each pixel in hand with statistical " fingerprint "of each area of interest. Practically, conditional probabilities were calculated of belonging to one class or another. The points in the middle of the group have a higher probability of belonging to the certain class, probability intervals (concentric isolines or contours of equal probability) being delimited graphically by izocontours expressing spectral variations within each set of training.

The risk induced by landslides on residential infrastructure, transport infrastructure and agricultural land causes problems of local management that need to be solved by reducing negative effects and decrease the frequency of their occurrence. This study followed the development and implementation of a model for identifying the risk induced by landslides through the analysis of spatial occurrence probability for landslides at the administrative territorial unit of șieu, following the semi-quantitative method governed in Romania by G.D. no 447/2003 and then through the exposure of housing infrastructure at landslides was possible to frame landslides on risk classes. The entire approach was based on GIS spatial analysis, creating a specific detailed database of causing and triggering factors of landslides and not at least, a database for risk receptors, in this study, represented by the constructions of villages associated with the studied administrative territorial units. The final result of the model highlights the framing of constructions on qualitative risk classes at landslides, revealing the elements of infrastructure that need post and pre event measures of protection.

Sweet cherry ( Prunus avium L.), originated around the Caspian and Black Sea, is an important fruit tree species of economic interest, and hence, breeding and conservation are requested (. Genetic analysis at the molecular level can be used effectively to study molecular polymorphism existing between intraspecific and interspecific tree species and phylogenetic relationships between them and their hybrids. The purpose of this study was to characterize and determine genetic relationships among the sweet cherry native genotypes belonging to Fruit Research & Development Station Bistrita, Romania, using RAPD markers. To eliminate the existence of possible synonyms from national romanian collection, we collect four Van cultivars, from four different national collection. For molecular analysis of the 16 varieties of sweet cherry were considered 13 RAPD primers selected from the literature. They were later used to determine the genetic variability at the molecular level using PAST program, and the dendrogram was generated based on Jaccard’s genetic distance. The dendrogram constructed by PAST software. The quantity and quality of the DNA obtained was suitable to achieve PCR amplification step. Only seven out of the 13 RAPD primers have generate polymorphic bands. The rest of seven were monomorphics. The most polymorphic primer was OPB10 which generated 11 bands from which 100% were polymorphic.Seven RAPD primers generated a high level of polymorphism which allowed to divide these cherry varieties into two groups according to their genetic geographical origin and the pedigree.

Introduction: In Europe between wheat cultivators countries, Romania ranks fifth with an area of 2.07 million hectares with a production of 7.45 million tonnes and production obtained is just 3601 kg /ha ( www.ager.press.ro ). Aims: Through the experience realised at ARDS Turda we follow the behavior of native varieties grEƒu autumn, compared E‹n varieties of foreign origin, to make recommendations on their pretability to different systems of culture and levels of fertilization. Materials and Method: The experiment realized at the ARDS Turda, includes two ways to work the soil, a classic conventional system (with autumn ploughing, land preparation, sowing and fertilized) in parallel with the conservative ("no-tillage†with stubble crop directly into the preemergent plant). Experimental factors: A - soil tillage system; B - winter wheat variety; C - fertilization. Results: Of the eight winter wheat varieties, in the experiment is remarkable the variety Capo   that registered highest values of the gluten content at the level of fertilization c2, c3 and c4 at cultivation in both work systems (classic and “no tillageâ€). At most varieties, the highest protein content is at the c2 level of fertilization, except Capo and Exotic that react the best at c3 level of fertilization, in the system "no tillage".

Aims: Through the experience realised at ARDS Turda we follow the behavior of native varieties grEƒu autumn, compared E‹n varieties of foreign origin, to make recommendations on their pretability to different systems of culture and levels of fertilization. Materials and Method: The experiment realized at the ARDS Turda, includes two ways to work the soil, a classic conventional system (with autumn ploughing, land preparation, sowing and fertilized) in parallel with the conservative (\"no-tillage†with stubble crop directly into the preemergent plant). Experimental factors: A - soil tillage system; B - winter wheat variety; C - fertilization. Results: Of the eight winter wheat varieties, in the experiment is remarkable the variety Capo   that registered highest values of the gluten content at the level of fertilization c2, c3 and c4 at cultivation in both work systems (classic and “no tillageâ€). At most varieties, the highest protein content is at the c2 level of fertilization, except Capo and Exotic that react the best at c3 level of fertilization, in the system \"no tillage\". Conclusion: The winter wheat indigenous Andrada, Dumbrava, Arieșan and line T-29-04 and cultivar Renan (Limagrain) reacts most favorable in gluten content at level of fertilization c2 (at sowing 250 kg/ ha NPK 20: 20: 0 + resumption spring vegetation E‹n 214 kg/ ha ammonium nitrate).

The use of herbicides abused, without a thorough knowledge can be dangerous for the environment through the introduction of toxic waste in agricultural ecosystems. It is necessary to reduce the doses used in relation to the use of conservative technology, finding solutions optimized for effective weed control. Research conducted at ARDS Turda in the years 2013 and 2014 have followed the effect of 12 variants of herbicides used to control weeds in soybean crop, sown in two tillage systems (classical system and minimal tillage system), on the soybean production and quality indicators. Tillage system significantly influenced both qualitative indices and soybean crop production (being 2635 kg/ha to the classical and 2131 kg/ha minimum tillage system). The significant influence of tillage soybeans in fat content (20.34% in minimum tillage system; 19.94% to the classical) and on protein (39.89% minimum tillage system; 40.56% in the classic).
