EFFICIENCY OF THE FERTILIZER SYSTEM IN THE TECHNOLOGY OF EMPOWERMENT OF WINTER WHEAT
06.00.00 Agricultural sciences
DescriptionWinter 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

EFFICIENCY OF USING COMBINED UNITS WHEN PREPARING SOIL UNDER WINTER CROPS
DescriptionIssues associated with the use of combined units in the preparation of the soil are relevant and of scientific and practical interest. Relevance increases when it comes to the cultivation of the main crop - winter wheat. In this regard, the presented results on the effectiveness of the use of combined units in the preparation of soil for winter crops are important. They are important primarily from a practical point of view. Experimental studies were conducted in the conditions of many years of stationary experience in the FSUE "ANC" Donskoy ", Zernograd, Rostov Region and in the Krasnodar region, LLC "Step". The efficiency of the use of combined units KUM-4, APK-4, developed at SKNIIMESH, now FSUE “ANC “Donskoy” in the cultivation of winter barley and winter wheat is considered. The technological process of tillage using combined units consists of several technological operations performed simultaneously. Disk working bodies chop plant residues and destroy weeds. At the same time, a network of cracks in the underlying soil horizons is laid. Next are flat-cutting working bodies that loosen the soil already at the set depth. There is a cutting of the root system of weeds, loosening the remaining non-loosened soil layer to the required depth, the formation of a flat bottom of the “furrow”, the separation of erosion-hazardous soil particles to the bottom of the furrow. Next, a roller - a compactor - compactor enters the work, which provides regrinding of soil lumps on the surface and subcompaction of the treated layer. The last in the process chain is a mulch roller, which ensures the formation of a compacted seed bed for seeds with simultaneous mulching of the compacted soil layer. The use of combined units in the technologies of cultivation of winter barley and wheat allowed to achieve a reduction in the number of technological operations by 1,5-2,5 times, an increase in the productivity of winter wheat by 0,4 t / ha (9%), a reduction in fuel consumption by 40%, operating costs 1,4 times with the economic effect of 1500 rubles / ha and the profitability of production of 140%

PERFORMANCE EFFICIENCY OF PEA BY USING MICRO-FERTILIZERS AND GROWTH REGULATORS
06.00.00 Agricultural sciences
DescriptionThe use of resource-saving technologies for cultivation of basic crops does not make sense without the use of microelement fertilizers, biologics and growth regulators. All this fully applies to the technology of cultivation of the main bean culture – pea. In the current market conditions of agrochemical products, microfertilizers are presented in a wide range. Identifying the most effective of them at a price and yield increase is a defining task for agricultural producers. In this connection, the purpose of the research was to study the influence of biologics and growth regulators on the development and productivity of peas with the definition of their most effective them. The studies were conducted in 2014-2016 on the fields of the training and demonstration center on the introduction of resource-saving technologies of the IPCC APK VO "DGAU" in Zernograd, Rostov Region. As the studied drugs there were used Rizotorfin, Extrasol, Vigor Fort, Miwal Agro, Flavobacterin, Biogumat Kubansky, KU-8 Agrofon. As a result of the research, it was established that all the preparations studied showed a positive effect on the development of pea plants grade Angela. The yield gain was 0,34-0,56 t/ha in comparison with the control. The most effective are the following ones: Extrasol with a yield increase of 0,56 t / ha (14,6%) and a profitability level of 232%, Mival Agro – 0,54 t/ha (14,1%) and a profitability level of 192%, Biohumat Kuban – 0,55 t/ha (14,3%) and the level of profitability of 271%. A good level of profitability was noted at KU-8 Agrofon – 224%

Description
The article presents the results of bio-energetic and economic evaluation of alternative technologies for cultivation of winter wheat, developed in long-term stationary experiments at Kuban State Agrarian University. We study the effect of four factors on the productivity of winter wheat, quality of soil, fertilizers system, systems of soil tillage and systems of protection. We have processed the data for 7 technologies in two rotations of 11 fields grain-grass crop rotation in the Central part of the Krasnodar region on leached black soil of plains of the agricultural landscape. We have established, in the first crop rotation, on the example of varieties of Batyka and Krasnodarskaya 99, that there were changes in costs of production, net profit and the cost of 1 centner of grain, depending on the technology, and the comparative evaluation of bioenergy impact of alternative technologies of winter wheat cultivation to consumption energy costs total energy. We have calculated ratio net of efficiency depending on the technology of cultivation of winter wheat. On the basis of economic and bioenergetic calculations for farms with different level of economy we have proposed an alternative technology: for economically strong, economically average, economically weak farms and for farms located in protected areas where is prohibited the use of chemicals. Thus, producers have a choice of alternative technologies of winter wheat, which will contribute to maximizing profits and obtaining competitive products

TECHNOLOGICAL ASPECTS OF SOIL DEPLOYMENT
DescriptionThe article presents the results of research on the impact of tillage technologies on the value of its density in the cultivation of winter wheat in conditions of insufficient and unstable wetting of the south of Russia. Experimental studies were carried out in the conditions of a long-term stationary experiment with a four-field crop rotation with different variants of tillage (dump, layer-by-layer, small, surface). The soil density was fixed at spring tillering of winter wheat and at the end of the growing season. Conducted analysis of variance shows that the soil has relaxation abilities, i.e. over time, it restores its properties by compaction ability, since studies conducted during the period of tillering of winter wheat show that Ffact. Ftable. (5,794,76), i.e. methods of treatment have an impact on soil compaction, which cannot be said for the case at the end of the growing season of winter wheat. The ability to restore its properties is a remarkable property of the soil, as it prevents them from over-compaction. The energy intensity of the compacted soil treatment increases to 30%, while the degree of crumbling is significantly reduced and its lumpiness increases. The most fundamental way to reduce the density of the soil is its timely loosening by working bodies of agricultural tools. Tillage methods affect soil density, the correlation coefficient between tillage methods and soil density varies between 0,929-0,979. The most radical way of soil decompression is exposure to it by a certain type of working bodies
