Purpose - to determine the cost-effectiveness of agronomy and different precursors winter crops sowing , fertilizers, plant protection products and items of biological farming systems . Experimental data on the effect of individual elements of the technology on the productivity of crops and grain quality. Adding different doses of fertilizer ensured the growth of winter wheat (average of varieties ) in fallow - from 6 to 7.6 g / ha ( 22-28 %) , the stubble - 2,1-6,4 g / ha (14 - 43%), for sunflower -1,3-8,9 g / ha ( 8-57 %). Best results are obtained in the form N30P60 + VVVN30 . Expenditure on fertilizer in this embodiment is fully paid off both predecessors and maturity . Growth in average yields of winter barley , depending on the dose of fertilizer is: the black couple - 2,2-7,5 g / ha ( 10-35 %) , the stubble - 3,3-6,2 g / ha ( 23-43 %) , sunflower - 3,0-9,6 g / ha ( 25-80 %). For all predecessors highest yield three crops formed at sowing 5.10 . and 15.10 . on average over three years. Cost-effectiveness analysis of all three growing winter crops showed that the lower cost of 1 quintal of grain was in terms of sowing October 5-15 , its growth has occurred in the later and the early stages , namely 5.09. , 15.09. and 25.10.
