In the article, the results of researches on influence of various agrotechnical receptions on prod-uctivity and quality of a winter wheat on a cornon-grain predecessor are resulted
The data about results of researches on revealing of optimum irrigation modes, features of water consumption of plants and definition of rational level of a mineral food of the cabbage which is grown up in an open ground in the conditions of an irrigation is cited in the article
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
The 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
New 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
The changing dynamics of nutrients in soil, doses of mineral fertilizers, efficiency, a mode of onion irrigation on irrigated soils of Rostov region are resulted in the article
The "Academician Trubilin" breed of grape with the colored pulp and juice is bred in Greece by P.Zamanidi, L.Troshin and L.Maltabar in 2003 by mating of the Greek breed of Armeletusa with French Alikant Bush. Duration of rule-oriented phase is 146-155 days. Productivity is high. The medial mass of racemations is 170 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds of Vitis vinifera L. Flower is bisexual. A racemation is medial, cylindrical with a wing, medial denseness. Bacca is small, roundish, blue-black color, with a dense wax coating. Peel is tight. Pulp and juice are intensely colored, with high quality tang. Sugar content is high. Differs with long preservation of crop on bushes. The breed is designed for production of intensely colored dry red wines of the excellent class, and also for high-grade dessert and sweet wines; it is applicable for making high-grade juice as well
