Methods of researches: field, laboratory field. Optimum conditions of formation of efficiency sorghum develop at sowing in ground, warmed-up on depth of 10 sm up to 18-20°С. It is expedient to sow late-ripening hybrid Genitsheskij-5/11 by the dotted method with row-spacing 45 sm, condensing crops up to 100-140 thousand plants on 1 hectares, and with row-spacing 70 sm and density of plants of 80-100 thousand pcs/hectares. Sort Genitsheskoje-209 forms the highest productivity of grain 4,09 ton/hectares in crops with a width of row-spacing 70 sm and density of plating 100 thousand plants/hectares. On crops with a width of row-spacing 45 sm productivity of grain is the highest at density of 100-140 thousand plants/hectares (3,97-3,82 ton/hectares), and in crops with solid way of sowing - at density from 120 up to 160 thousand plants/hectares - (3,79-3,94 ton/hectares). In case of sowing by solid method with density of crop 120-160 thousand plants on 1 hectares hybrid Stepnoj-8 forms 4,5-4,65 ton/hectares of grain. In crops with a width of row-spacing 70 sm and density of plants of 100 and 120 thousand pcs/hectares productivity of grain increases up to 4,74-4,68 ton/hectares; with a width of row-spacing 45 sm and density of plants from 100 up to 140 thousand pcs/hectares - up to 4,62-4,94 ton/hectares. Scientific novelty of the received results consists that the basic receptions of high-quality agrotechnics of hybrids and sorts of new generation grain of sorghum have been developed for conditions of steppe Crimea and in concrete conditions of a zone reaction of plants to change of conditions of the environment caused by variability of technological actions is revealed, their insistence to an agrotechnical background is found out and optimum parameters of cultivation are developed. Profitability of grain production in optimum terms, methods of sowing and density of plants grain sorghum changes in borders from 10,6 % up to 24,8 %.
