Purpose - to determine the agrotechnical and economic efficiency of various precursors of winter crops, tillage systems, seeding time, fertilizer, plant protection and biological elements of agriculture. The implementation of these scientific developments in production will more efficiently use the main crop in the steppe limitative factor - moisture based on the degree of differentiation and intensification technologies. The work will not only identify the factors that most influence the formation of grain yield, but also to determine the economic feasibility of specific agrotechnical measures. The obtained experimental data the influence of individual elements of technology (fertilizer, sowing dates, predecessors) on the productivity of cereals and grain quality. Fertilizers. Introduction of different doses of fertilizer provided growth yield of winter wheat on the black pair - from 8.2 to 14.8 t / ha (40-72%) in sternovomu predecessor from 9.3 to 16.3 t / ha (66-116% ), sunflower - from 4.2 to 18.3 kg / d (40-176%). The average yield of winter barley, depending on the dose of fertilizer, was as follows: - On the black pair - 2,8-6,7 kg / ha (14-35%); - In winter wheat - 4,4-7,4 kg / ha (32-55%); - Sunflower - 4,2-18,0 kg / ha (44-188%). Seeding time. In all predecessors maximum yield all three crops (winter wheat, winter barley, winter triticale) formed by seeding 15.10.10r. Compared with the control (generally available sowing 9.25) yield of winter wheat increased, depending on the predecessor to 5,7-10,3 kg / ha (17-45%). Yield of winter barley by planting 15.10: - On the black pair - 25.9 kg / ha; - In winter wheat - 24.4 kg / ha; - On corn silage - 22.4 kg / ha. Reduced yields in sternovomu predecessor compared to the black vapor was greatest for planting 5.9 - 8 kg / ha (38%) of corn silage 9.15 - 8.6 kg / ha (34%). Reduced harvest of winter triticale on deteriorating predecessor was most important for seeding 25.10 - 7,3-8,1 kg / ha (34-37%).
