ECONOMIC AND BIOENERGY ASSESSMENT OF ALTERNATIVE TECHNOLOGIES OF WINTER WHEAT CULTIVATION IN THE CENTRAL ZONE OF THE KRASNODAR REGION

abstract 1381804012 issue 138 pp. 60 – 77 30.04.2018 ru 50
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

EFFICIENCY OF THE FERTILIZER SYSTEM IN THE TECHNOLOGY OF EMPOWERMENT OF WINTER WHEAT

abstract 1331709039 issue 133 pp. 498 – 504 30.11.2017 ru 53
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

IMPROVING THE QUALITY OF FINE SOIL TREATMENT OF HORIZONTAL DISK WORKING ORGANS

abstract 1181604004 issue 118 pp. 75 – 86 29.04.2016 ru 385
The creation of machines and tools of new generation, which represent high-efficiency, highperformance and take less energy and metal is a global challenge for the modern science. In this article, based on numerous studies, it is proposed to use the effect of oscillatory motion in the working body of tillage, improving the design of tillage machines that aims to reduce metal consumption, energy intensity and improve quality of work. A new tillage working body, running in a horizontal plane and having special tabs (blades) allowing it to make a reciprocating rotational motion has been presented. The application of this working body provides agronomic, environmental, energetic and economic efficiency by trimming the layer of the soil and root system of weeds, crumbling soil layer during its interaction with the working surfaces of the blades. Due to the reciprocating rotational motion, the cleaning of the working body is observed. The constructive and technological scheme of the working body and the scheme of forces acting on the proposed working body at the moment of penetration and the rotation of the working body at a certain angle are offered. The conditions for the reciprocating rotational motion of the working body are obtained as well as differential equations allowing considering the process of movement of the working body. The article also reveals expressions for the elementary forces acting on the surface of the blade from the moving layer of soil

INFLUENCE OF THE TECHNOLOGY OF TILLAGE ON THE MOISTURE OF THE PRO-CESSED LAYER

abstract 1351801002 issue 135 pp. 50 – 57 31.01.2018 ru 25
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

OPTIMAL PARAMETERS OF TECHNOLOGICAL LINE FOR LOADING TOBACCO LEAVES INTO CONTAINERS

abstract 1211607068 issue 121 pp. 1098 – 1109 30.09.2016 ru 183
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
