The paper aimed to present the quality of some soils from the West Region from Romania. The soil types who were studied occupied a surface of 54250 ha in the south part of Timiş Department and the East part of Caraş-Severin Department. This two part of departments are included in one area named Barzava Plain. It was made analyses in two depths 0-20 cm and 20-40 cm and was studied some physical and chemical properties of soils like pH, soil texture, humus content, total nitrogen content, P2O5 content and K2O content. The main soil types who was founded in this area is Fluvisols (gleyic, vertic and haplic) on 6.72% from the entire surface, Chernozems (calcic, haplic, gleyic, hyposodic, vertic, luvic) on 6.97% from the surface, Haplic Phaeozems, Cambisols (mollic and gleyi-eutric) on 0.5% from the surface, Luvisols (vertic and stagnic) on 39.4% from the surface, Haplic Luvisols on 5.49% from the surface, Vertisols (pellic-gleyic and pellic-stagnic) on 27.66% from the surface, Gleysols (haplic and mollic) on 3.08% from the surface, Stagnosols (haplic and vertic) on 3.08 from the surface and Antrosols on 1.80% from the surface. The soil analyses was made on Laboratory from Soil Science Department from Faculty of Agriculture on Timişoara. The obtained results was compared with the Romanian Pedological Studies Elaborating Methodology, 1987.

The paper presents an analysis on market elements that can influence the decision to cultivate rapeseed. We have studied the market features as estimators on market supply-demand ratio (the annual production, imports and exports of rapeseed) and the area under rapeseed production as concrete estimator on decision to cultivate. Inter-conditionality analysis between estimators of market and the estimators of decision to cultivate, made for a time interval of 12 years (2002-2013) emphasized that, in the Romanian market of rape, one of the significant factors influencing the decision to growth (taken in the previous year at seeding) is the value of exports of rape in the harvest year. It also revealed that in recent years, it has generated a system of specialized farms in rapeseed production associated to the international market requirements. It also highlighted the fact that domestic market of rapeseed (understood as internal consumption) does not influence the decision to cultivate rapeseed, it behaving more as a residual market in relation to the export market.

Written by Mirela COMAN, Bogdan CIORUŢA, Remus POP

The pollution of the soil and of groundwater represents an environmental issue which is as old as complex, with regard to the migration mechanisms of various pollutant substances in both the soil and the subterranean environment. Also, soil pollution, in terms of food safety and drinking water, is a problem of permanent actuality. The paper presents the results of the research carried out in Săcel oilfield (Romania) that is currently under preservation. The results of the sample collection show that, in terms of legislation, the quality of the soil here falls below the threshold of intervention for sensitive types of use; from all the samples collected, 26.31% fall under normal values, 23.68% are within the normal limit alert threshold for sensitive land use types, and 7.90%, situated at a depth of 30 cm, exceed these normal values for the content of oil pollutants in the soil. In terms of protection of the soil resources and environmental protection, detailed knowledge of the content of pollutants and processes of selfpurification occurring in these soils are key factors for establishing measures and ameliorative actions needed to recover the economic value of the affected land. By observing this process in all the perimeters from where soil samples were taken, one can conclude that the self-purification process is the result of the intimate and concrete interaction in time between pollutant-oil residue and the soil - a living body capable of self-regeneration.

The study aimed at investigating the presence of various variants of the IBV by RT-PCR in Romania, the territory being divided into four main regions: Q1-North West (n=78), Q2-North East (n=68), Q3-South East (n=173) and Q4-South West (n=53) to provide information for improvement of vaccination protocols and IBV infection overall control strategies. Two types of RT-PCR were applied to characterise the strains from the 33 farms. Numerous variants of the IBV virus were identified in different farms of the four major regions of Romania, with the obvious dominance of 4/91. Nevertheless, the identified pathotypes, of which some not mentioned in Romania, like Xinandi which might have been “imported” from Turkey or D1466, mentioned elsewhere in Europe, did not overlap the vaccine strains, leading to the clinical expression of the disease with different degrees of severeness, which stands for IBV versatile character and potential re-combinations occurring in spite of affiliation of certain variants to various geographical areas.

The paper aims to present the evolution of the ichtyofauna from Comana Nature Park, since 2011, on the watercourses of the Neajlov River, Comana Pond or Neajlov Delta, Gurbanu river and Putu-Greci ponds. In the past, have been identified on these waterways inside of the protected area, fish species protected at national and community level, such as grig (Cobitis taenia), eel (Misgurnus fossilis), boart (Rhodeus sericeus amarus), glossy ibis (Umbra krameri), or endemic - Comana chub (Leuciscus borys thenicus). In 2011 it was finished a project for ecological restoration of the Neajlov Delta, that which built a dam on the river Neajlov, the results being flooding the pond and getting a permanent body of water by 40%. The effects of this ecological restoration were the increased of populations of birds and especially fish eating populations, improvement of the habitat and recovering of whole aquatic ecosystem. It is required that the process of monitoring the fish species to continue because is very important to know them evolution as a result of the implementation of the ecological reconstruction, and also to monitor the other wetlands from the protected area for identified the effect of restoration on them. The importance of the research is that the declaration of the nature park was based on existing inventories of species in 1998, and the absence of updates based on extensive research, makes that the management of the area becoming ineffective.

This paper aims to quantify the qualitative and quantitative parameters of milk production at goats from Carpathian breed in relation with the breeding system (extensive versus semi-intensive). To determine the total quantity of milk, the milk production control it included suckling period of kids and milking period of goats. For determining the quality of milk it was made the analysis of chemical composition of milk in the main constituents, namely water and dry matter, content of fat, protein, lactose and minerals. The biological material studied in this paper was represented by the adult goats from Carpathian breed belonging of two private farms from the south region of country. The size of the control group during the whole lactation was 25 heads for each farm. The research took into account two farms of goats differentiated by breeding system practiced, respectively extensive and semi-intensive. The obtained results showed that regarding the quantitative milk production the best performance was achieved by animals from semi-intensive farm (253.21 liters versus 208.50 liters) and in terms of milk quality by the animals from extensive farm

This review study aimed to give information about the use of plant extracts in meat product processing as antimicrobial and antioxidant agent. Microbial spoilage and lipid oxidation are the major causes of the deterioration and reduction of shelf-life in meat products. Lipid oxidation in meat products results in formation of off-flavors and undesirable chemical compounds such as aldehydes, ketones, alcohols and hydrocarbons. Growth of microorganisms in meat products causes not only microbial spoilage but also development off oodborne diseases. To inhibit lipid oxidation and growth of microorganisms, especially pathogenic microorganisms in meat products, several preservation techniques, such as pasteurization, reduction of water activity (salting, drying, freezing etc.), acidification, fermentation, synthetic and natural antimicrobial and antioxidant additives have been used in meat industry. Many synthetic and natural food additives such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), propyl gallate, α-tocopherol, nisinand organic acidsare commonly used in the meat industry to inhibit or delay the oxidation process and reduce the microbial growth. In recent years, consumer demands for natural food additives have increased because of negative and toxic effects of synthetic food additives on human health. Herbs, spices, fruits and vegetables, and their powders, oils and extracts have been reported to be a good source of various phenolic compounds, such as flavonoids, terpenoids, carotenoids, could therefore be incorporated in meat products as a source of natural antioxidants and antimicrobials to extend shelf-life and safety of meat products.

Published in AgroLife Scientific Journal, Volume 7, Number 1
Written by Aurel CĂLINA, Jenica CĂLINA, Marius MILUȚ, Ion STAN

The research realised in this paper was based on ecologic principles such as: stimulating forestry and hunting funds to participate in the rural tourism market, protecting game species through improving life conditions, strict control of the number of pests and combating illegal hunting (poaching); encouraging biodiversity conservation through sustainable nature-based tourism. The paper argues the necessity of conforming hunting tourism to modern tendencies which involve responsible travelling to natural areas. The study of the reliability of the main game species, quantitative and, qualitative value indicators, as well as the optimal number of animals, the influence of the anthropic factors reflected in how to manage the hunting fund, the theoretical calculation of harvesting quotas and the comparison of the real and optimal ones, the combating of game pests are all elements that we consider to be extremely important in solving the proposed objectives, in order to create the best premises and conditions for rural tourism practices specializing in image hunting.

The work was accomplished within a research project which aimed to streamline the resource management on the campus of the University of Craiova by creating a GIS database using a new technology that is increasingly being applied in topo-cadastral works, namely aerial scanning using drones. The main objectives of the research were represented by obtaining an orthophotomap using air scanning (the orthophotomap becoming the GIS raster graphical support) designing, validating and implementing a data model (database), using specialized software products. In the case study carried out at the University of Craiova, the following steps were also taken: obtaining raw data, processing raw data and obtaining an orthophotomap, designing the data model (database) and implementation of the data model (database). The research proves of interest primarily through the conceptual foundation of the applicable data model, a model that will allow the recording, storage, extraction, processing and efficient analysis of the desired data. The system is based on a relational open model, which permits it to adapt according to specific needs. The design data model has applicability on the structure of any student campus and can be implemented in other locations (with the provision of the related graphic support).

Written by Cristina Andreea OPREA, Doru Ioan MARIN, Ciprian BOLOHAN, Aurelian PENESCU

The fertilization is an essential technological factor in improving yield. The purpose of this research was to evaluate the effect of fertilization and the answer of grain sorghum hybrids in terms of yield and its components. Research conducted over two agricultural years (2013/2014-2014/2015) was located in the South-Eastern Romania area and was based on a split plot design. The paper presents the results regarding the following tested factors: Factor A- grain sorghum hybrids: Alize, Aquilon, Arack; Factor B - fertilization levels: N0P0, N90P0, N90P60, N120P0, N120P60. Regarding fertilization, both the use of nitrogen (N) and the fertilization with complex fertilizers (nitrogen and phosphorus) generated the increase of yield and its components with values statistically assured for the three researched hybrids. The average yield was 7.83 t/ha, varying from 5.61 t/ha (Arack hybrid unfertilized) to 9.22 t/ha (Aquilon hybrid fertilized N120P60). Hectolitre mass was highly significant influenced by the use of fertilizers, the highest value (80.74 kg/hl) being recorded by the hybrid Arack fertilized N120P60. The maximum value of a thousand seeds weight was recorded by the hybrid Aquilon fertilized N120P60 (24.15 g) and the lowest value was recorded by the hybrid Alize unfertilized (19.03 g) with variations between +0.95 g (Arack hybrid fertilized N90P0) and +3.56 g (Aquilon hybrid fertilized N120P60).
