EFFECT OF DRIP IRRIGATION ON SOIL SALINIZATION
06.00.00 Agricultural sciences
DescriptionThe article presents the results of researching into the effect of drip irrigation on build-up of soil salinity using water with high salt content and the dynamics of changes during winter period under atmospheric precipitation. It was established that at the end of irrigation season zones with high salt content formed on the soil surface under drip irrigation using sodium sulfate water, among these salts gypsum was presented. In spring time the increasing of sodium sulfate content was found that indicates the exchange reaction with soil exchange complex passed as well as the insufficient salt leaching occurred during the winter period. In spring time the upper soil layer characterized with alkaline type of soil salinization

ROLE OF UNCERTAINTY AND RISK IN CONTEMPORARY ECONOMICS
DescriptionIn the article the new role of risks is estimated on the basis of the review of the modern economics condi-tions and its conjuncture, stochasticity and unpredictability of variables. Dyadic generalized risk vector in two-dimensional space is designed from vectors of “usual cost” and “risky cost”. It enables analytically to calculate the generalized risks of consecutive logistical chains

NEW COMPLEX-STEADY HIGH-GRADE TECHNICAL BLACK BERRY VARIETY OF GRAPE - ALEKSAMPELO
06.00.00 Agricultural sciences
DescriptionNew complex-steady black berry technical kind of a grape - "Aleksampelo" is breed in Greece by P.Zamanidi and L.Troshin in 2003 by mating of Firstborn Magaracha with a mixture of blossom dust of Greek black berry sorts of Bakuri and Mavrostifo. Duration of productional phase is 146-155 days. This sort is сильнорослый. A degree of ripening of a vine is very high. Productivity is high. The medial mass of racemations is 230 gr. It differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with sorts of Vitis vinifera L.; it is tolerant to a phylloxera. A flower is bisexual. A racemation is medial, cylinder-conical, medial denseness. A bacca is medial, roundish, blue - black colour, with a dense wax coating. A peel is tight, strong. Pulp and juice with the expressed high quality flavour. Sugar content of juice of baccas is very high. The crop is maintained on bushes duratingly enough. The sort is designed for production of dry red wines of the excellent quality and also for high-grade dessert and sweet wines; it is applicable for development of high-grade juice and compotes as well
