EFFICIENCY OF IRRIGATION REGIMES FOR GRAIN SORGHUM ON CHERNOZEMS
06.00.00 Agricultural sciences
Description
The article results the study of irrigation regime im-pact on water consumption and yield of grain sor-ghum. It is established that optimal conditions for growth and development are created by maintaining soil moisture content in a soil layer of 0.6 m higher than 80 % of field capacity (FC), where the grain yield reaches 14 t/ha and the best indices of profit and cost-effectiveness are obtained

EFFICIENCY OF THE FERTILIZER SYSTEM IN THE TECHNOLOGY OF EMPOWERMENT OF WINTER WHEAT
06.00.00 Agricultural sciences
Description
Winter wheat is very demanding on the nutrient regime of the soil. Like many winter crops, it consumes the nutrients unevenly distributed during the vegetation period, which must be considered when making them. Modern varieties of winter wheat are very demanding to soil fertility. For the formation of 4,0-4,5 t/ha requires about 140 kg of nitrogen, 50 kg phosphorus and 120 kg potassium. Therefore, without the use of fertilizers, it is not possible to obtain such a crop with high grain quality. In addition, in the cultivation of winter wheat in the high and intensive technologies simply need using large amounts of fertilizer to compensate for the removal of nutrients. This is especially important when having partial or complete reduction of application of organic fertilizers. Therefore, we consider the possibility and the results of studies using different doses, combinations and types of fertilizers in technology of winter wheat cultivation. Experimental studies were carried out in the conditions of insufficient and unstable moistening of southern zone of Rostov region, on experimental fields of the federal state scientific institution «ASС «Donskoy». For research, we have chosen the most common varieties of winter wheat (Tanais, Granite, Axinite, Terra, Donskoy prostor, Motto) and various combinations and combinations of mineral and organic fertilizers. The experiments were conducted on two predecessors: couples and peas. As the controllable parameters we had the productivity and quality of winter wheat. We have found a positive impact of the in-change of fertilizer on the studied parameters with a share of the variance of 96% and a high degree of correlation of 0,98. The marked increase in the productivity of winter wheat is up to 22% when using different versions of the experiment. We have identified rational combination doses of mineral and organic nutrition for predecessors: peas N40P60K40+2N30 and vapor – manure 40t/ha+2Р60+2N30

EFFECT OF DRY BAKERY YEAST SACCHAROMYCES CEREVISIАE IN MILK COWS DIET
06.00.00 Agricultural sciences
Description
The effect of dietary supplementation with dry bakery yeast culture Saccharomyces cerevisiae in high concentrate diet (F:C=47:53) on milk yeald and rumen fermentation were studied on two groups primiparous lactaiting cows (8 cows per group) and four ruminally cannulated nonlactaiting cows on diet F:C=25:75. Cows fed yeast during 67 days produced 1.24 kg/d and 1.66 kg/d natural and 4% fat corrected milk respectively more, than control cows. Milk protein and fat percentages were also higher. On diet with yeast ruminal concentration of lactate was lower and butirate+propionate was higher. The yeast incrised rumen pH, decreased NH3 in rumen and urea in blood, decreased viscosity of rumen fluid

EFFICIENCY OF CHEMICAL FUNGICIDES AGAINST LEAF TAN SPOT OF WHEAT
06.00.00 Agricultural sciences
Description
In recent years leaf tan spot had dominated into pathogenic complex of wheat in southern Russia. The causative agent of this disease is hemibiotrophic ascomycete Pyrenophora tritici-repentis (Died.) Drechsler; imperfect state of Drechslera triticirepentis (Died) Shoem. It causes two different symptoms in susceptible wheat varieties: chlorosis and necrosis. Under epiphytotic disease progression crop losses can achieve 65%. One of the most important elements of phytosanitary control of wheat cenosis is scientifically relevant chemical fungicides application. Biological efficiency of some fungicides against Pyrenophora tritici-repentis has been estimated. Research was conducted on the experimental ground of FSBSI ARRIBPP on the variety susceptible to the pathogen – Krasnodarskaya 99. Preparations were tested one time at leaf-tube formation (Z37) phase or two times: at leaf-tube formation (Z37) and start of heading (Z51) stages. Double treatment was more effective than a single one. Fungicides “Amistar extra” and “Prozaro” have got the high biological efficiency – 80,7 and 83,7%, consequently, and longer protective period (up to 40 days) in comparison to every tested fungicides
