In the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established

In the article, we have stated the agro-technical requirements to a pre-seeding processing of soil. The results of experiments of the combined soil-cultivating unit are resulted. Operating modes of the unit with optimum width of capture, uniformity of a surface of soil, quality of crushing the soils meeting agro-technical requirements are proved

In this article, we have given a short review of scientific bases of designing of blocks and module cars and some perspective works for opening new possibilities of increasing the efficiency of technologies of intensive mountain and foothill gardening

This article considers the criteria of the efficiency of means for antierosion processing of soil with reference to industrial-economic conditions of the Kabardino-Balkarian republic

This work is devoted to the research of the thin-walled cylinders’ surface roughness dependence upon the modes of processing by the roller head. The research was made on the machine 1K62, preliminary treatment – boring and unfolding

In the article, main principles and methodical bases of the complex analysis of actions for research of influence of influences on soil subject to erosion are stated at cultivation of agricultural crops for the purpose of preservation and increase of its fertility

This article considers factors which are necessary for considering at application of the minimum processing of soil. The scheme of power saving processing of soil and the scheme of the minimum processing of soil in a crop rotation with good water penetration are offered

From a review of the literary sources it is revealed that the existing vibration exciters are classified into mechanical, electrical, hydraulic and pneumatic. One of the most promising areas of development and use of sources of vibrations for tillage tools are electrical exciters of mechanical vibrations namely solenoid with a metal core inside. Based on the analysis of existing technical means for soil cultivation we are proposed a new technical mean of vibration exposure for tilting the soil without or before ploughing. Theoretical regularities of change of draft resistance depending on the vibration amplitude and the mass of the vibration exciter were received in the studies. A structurally - technological scheme of the combined tillage combine with electric vibration exciter and a device for automatic regulation of the technological process of the work of tillage machine was developed. The proposed vibration tool will supposedly reduce the soil resistance force acting on the working bodies, which will reduce energy costs up to 20% for the technology process of soil cultivation; harmful emissions from the combustion of diesel fuel into the atmosphere were reduced. The proposed technical mean can be used for soil cultivation in different soil fertility under different soil density

In the article, we have considered the questions of mathematical modeling of a combined soil-cultivating unit. Theoretical dependences and rational values of parameters and unit operating modes are received
