INFLUENCE OF PREDECESSORS AND TECH-NOLOGIES OF PROCESSING ON DEVELOP-MENT OF WEEDS
Description
Issues 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

INFLUENCE OF THE TECHNOLOGY OF TILLAGE ON THE MOISTURE OF THE PRO-CESSED LAYER
05.20.00 Processes and machines of agroengineering systems
Description
Currently 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

OPPORTUNITIES TO REDUCE OPERATING COSTS IN THE PRODUCTION OF LEGUMINOUS CROPS
05.20.00 Processes and machines of agroengineering systems
Description
The 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

USING MICRONUTRIENTS AND GROWTH REGULATORS IN THE CULTIVATION OF WINTER WHEAT
Description
The introduction of innovative technologies of cultivation of priority crops is not possible without the use of biologics. Their incorporation into the soil or on the leaf surface allows achieving a significant increase in productivity and production quality. Currently, on the market of agrochemical products, micronutrient fertilizers offer a wide and varied range of products, both foreign and domestic production. To select the most appropriate preparations or their combinations in price and the resulting effect is a complex task. Therefore, the aim of this study was the study of living forms of microorganisms and growth regulators on development and productivity of soft winter wheat called Yuka. The research was carried out in 2013-2015 in the fields of training and demonstration center for sustainable technologies in FSRI of the «ASC «Donskoy». As the test drugs we used Extresol 1/t seeds and vegetation 1l/ha; Agrophone KU-8 seeds 2 l/t of the growing season is 2 l/ha; seed Vigor forte of 0,50 g/t on vegetation of 0,25 g/ha; Flavobacterium 1,2 l/t seeds and 0,3 l/ha during growing season; Rostock 0,3 l/t and 0,2 l/ha during growing season; Risotorphine 1,2 l/t and 0,4 l/ha during growing season. As a result of researches it is established that living forms of bacteria preparation «Extrasol» and the growth regulators affected the productivity of winter wheat. The yield increase was from 0,53 t/ha to 0,66 t/ha. Huge positive role was played by biological technology of utilization of plant residues with the use of biological products and growth regulators. The introduction of this technology in the training and demonstration center for the production of winter wheat allowed to get 4056 Rub income from 1 ha, at the level of profitability 158%

TO THE QUESTION OF HARROWING AND SIMULTANEOUS FEEDING
Description
The technology of cultivation of most crops provides pre - and post-emergence weeding of crops, and their feeding with the availability of soil nutrients. According to the used underlying technology, these operations are performed separately. The harrowing of crops after germination is necessary for weed control, the destruction of the soil crust for access of air to the root system and partial thinning of dense crops. Further destruction of weeds on crops are herbicides, high-quality entry which provide sprays. The latter can provide small and ultra-low volume spraying in high performance and environmental requirements. However, separate execution of technological operations for fertilizing and harrowing reduces the quality of work, increases the cost of production. The proposed combination of technological operations on a harrowing of crops different crops simultaneously with feeding plants solid mineral fertilizers. The combination of technological operations for one pass of machine-tractor unit in the field provides a reduction of the fleet, its capital intensity, the energy, cash costs, and hence competitiveness of products. The studies proposed new technical support processes, technological scheme of the multifunctional unit to combine the operations of feeding and harrowing of crops

THE RATIONALE FOR THE USE OF COMBINED UNITS IN THE CULTIVATION OF WINTER WHEAT
06.01.01 General agriculture, crop production (agricultural sciences)
Description
Issues related to the use of combined aggregates in soil preparation are relevant and of scientific and practical interest. The relevance is increased when it comes to the cultivation of the main crop – winter wheat. In this regard, the presented results on the efficiency of using combined aggregates in preparing soil for winter crops are important primarily from a practical point of view. Experimental studies were conducted in the conditions of long-term stationary experience in the Federal state budgetary institution «Agrarian Science Center «Donskoy», Zernograd, Rostov region. The article considers the efficiency of using the combined unit APK-4, developed in "SKNIIMESH" now Federal state research institution of the «Agrarian Science Center «Donskoy» in the cultivation of winter wheat. The structural and technological scheme of a combined unit, the technological process of which consists of several technological operations performed at the same time, is justified. Disk working bodies crush plant residues and destroy weeds. This creates a network of cracks in the underlying soil horizons. Next, there are flat-cutting working bodies that loosen the soil to a set depth. The root system of weeds is pruned, the remaining loosened soil layer is loosened to the required depth, the formation of a smooth bottom of the "furrow", and the separation of erosive soil particles to the bottom of the furrow. Next, the roller starts working – a lump-crushing sealer, which provides crushing of soil lumps on the surface and sub-compaction of the treated layer. The last in the technological chain is a mulching roller, which provides the formation of a compacted seedbed for seeds with simultaneous mulching of the compacted soil layer. The use of the combined unit in the technology of winter wheat cultivation allowed to reduce the number of technological operations by 1,5-2,5 times, increase the productivity of winter wheat by 11-13% and the cost of production by 10,4-18,3 %

OPTIMAL PARAMETERS OF TECHNOLOGICAL LINE FOR LOADING TOBACCO LEAVES INTO CONTAINERS
Description
The article presents the research results on parameters optimization of technological line for loading tobacco leaves into containers. The aim of the research was decreasing labor expenses on preparing tobacco for artificial curing. This was achieved by line modernization utilized for loading tobacco leaves into containers. We have also developed working parts of technological line for automatic loading of tobacco leaves into containers. Researches on weight studying of tobacco leaves of 3 sorts zoned in the Krasnodar region have been carried out. Dispersion analysis has not revealed weight differences between sorts, therefore, further researches can be carried for one sort. Optimization of working part for loading tobacco leaves into containers was carried by analysis of regression equation obtained by bifactorial experiment. Irregularity of leaf position was taken as optimization criterion. It has been discovered that optimal regimes: transporter belt speed v=2,8m/s, number of transporter’s double movements n=19 min-1 can be used for uniform container loading by leaves. Researches on studying line capacity on leaves position irregularity revealed that maximal uniformity obtained when line capacity is 260 kg/h
