Purpose - to identify agricultural and economic efficiency of various precursors of winter crops, processing systems, sowing, fertilizers, plant protection and biological elements of farming systems. Experimental data the effect of individual elements of technology (fertilizer, sowing, precursors) on the performance of crops and grain quality.  The introduction of different fertilizer rates ensured the growth of winter wheat yield (average of varieties) on the black pair - from 1.5 to 5.1 t / ha (9-13%), and stubble predecessors from 1.0 to 4.8 kg / ha (12-57%), sunflower - from 1.1 to 4.0 kg / d (19-68%). All these yield increments were too small and the use of fertilizers in the current year to be economically impractical. This is due to difficult weather conditions of the growing season, namely the lack of rainfall and disparity in prices for s / s products.  The maximum yield of winter wheat on fallow formed and sunflower at sowing 05.10.11g., Predecessor to winter wheat - 25.09.11g. Compared with the control (conventional sowing times 9.25) winter wheat increased, depending on the predecessor to 0,5-3,1 kg / ha (6-20%). The decrease of the yield deterioration predecessor was the most significant at sowing 5.10 - 8.4 kg / ha (45%) and 15.10 stubble predecessor - 10.2 c / ha (59%) in sunflower. Winter triticale showed the best results on a black pair and a sunflower at sowing - 10/05/11, according winter wheat - 25.09.11, the The effect on grain yield of winter triticale were equivalent sowing: the fallow - 25 September and 5 October, to stubble predecessors - September 25, 5 and 15 October, for sunflower - 15.25 on September 5 and October 15. Ie the deteriorating effect of sowing predecessors leveled. The reason is the same rate of growth and development of plants under adverse drought conditions in 2012.
