OPPORTUNITIES TO REDUCE OPERATING COSTS IN THE PRODUCTION OF LEGUMINOUS CROPS
05.20.00 Processes and machines of agroengineering systems
DescriptionThe article considers the possibility of reducing the cost of tillage in the production of grain crops. The most important economic characteristic of production is operating costs. In terms of agricultural production, they represent the amount of contributions to wages, depreciation, repairs, and the cost of fuel, lubricants and other consumables. In this regard, the aim of the research was to determine the dynamics of operating costs in the production of legumes. Determination of the dynamics of operating costs was carried out on the basis of the results of studies of energy-saving technologies in a stationary experience. Variants of processing of the soil on the conventional technology was layered subsurface tillage combined unit, UNS-3, the layered subsurface tillage unit CUO-2 and conventional tillage (PN-5-35). No provision was made for zero tillage technology. As a result of the research it was found that on pre-sowing tillage and sowing, the value of operating costs varies for the crops under consideration, but has almost the same values (within each crop) for the methods of the main tillage. More preferable for this type of work is zero tillage, as it provides 21-29% lower operating costs due to direct sowing of crops. The highest operating costs for all the crops under consideration are observed in the main tillage. In the same technological period of work operating costs are the most variable. Thus, depending on the technology of the tillage when growing winter wheat, they change within 117,2-5229,2, the production of spring barley - to 167,8-4517,4 and in the production of peas – to 136,6-4517,4 thousand rubles

INFLUENCE OF THE TECHNOLOGY OF TILLAGE ON THE MOISTURE OF THE PRO-CESSED LAYER
05.20.00 Processes and machines of agroengineering systems
DescriptionCurrently in the South of Russia, the most acute problem of accumulation and preservation of productive moisture in arable layer of soil. This fact has a decisive influence on the yield of agricultural crops. The need to study the dynamics of accumulation of moisture of the treated soil due to the fact that at the first stage of development plants are very sensitive to moisture content in the rooting zone of the soil. Practically the regulation of the moisture content of the processed layer may correct the influence of soil tillage aggregates with different types of working bodies. The work was performed in FSRI of the «ASC «Donskoy» (Zernograd, Rostov area), in the conditions of stationary experience (4,3 ha), 2013-2015, where explores various technologies of soil treatment, including no treatment. To obtain comparable results the same selected set (rotation) of crops (winter wheat, spring barley, pea, vapor). As a result of researches it is established that on steam background (76,1-46,2 mm) content of productive moisture is more than two times higher than on other backgrounds (of 30,6-46,2 mm). This allows us to talk about the effectiveness of the fallow field from the point of view of accumulation of moisture. The analysis of statistical data allows making a conclusion about the impact of crops on the dynamics of productive moisture. On the other hand, the rating statistics of the received data with backgrounds treated with different technologies did not allow to find significant advantages to any of them, as the area under the curve ROС analysis does not exceed the value of 0,6. Therefore, the studied backgrounds in the period of the research have equal influence on the moisture content of the treated soil layer

INFLUENCE OF PREDECESSORS AND TECH-NOLOGIES OF PROCESSING ON DEVELOP-MENT OF WEEDS
DescriptionIssues related to the contamination of crops are topical and very relevant. All this fully applies to the main crop produced in the South of Russia – winter wheat. In this regard, the presented results of studies of the influence of predecessors and tillage technologies on the development of weeds in the cultivation of winter wheat are relevant. Experimental studies were carried out in conditions of many years of experience located in the FEDERAL state scientific institution «ANTS «Donskoy». The influence of different methods of sowing (ordinary, scattered, belt) and technologies of tillage (dumping, non-dumping, surface, small) on infestation of winter wheat is considered. It is established that the least amount of weed plants is provided at scattered sowing on the background of deep tillage. The main treatment at a depth of 18-20 cm reduces the number of weeds by 47% in comparison with the surface (8-10 cm), and the scattered sowing reduces their number by 80%, since weeds are in more severe conditions compared to winter wheat, the rapid development of which contributes to the optimal nutrition area. Of the predecessors, the most acceptable is the steam with the number of weeds 7-25 PCs / m2, which is several times less than after peas, or corn after silage
