Aim - to define agrotechnical economic efficiency of different predecessors of winter crops, terms of sowing, fertilizers, defence of plants and elements of the biological system of agriculture. Theoretical and practical results. The elements of zonal technology are worked out growing of winter-annual grain-crops, adapted on basic parameters to the terms of economies of different economic status and resource providing. Bringing of different doses of fertilizers provided the height of the productivity of winter wheat (AV on sorts) on black steam is a from 0,59 to 1,43 ton/of ha (25-60%), on a stubble predecessor a from 0,54 to 1,09 ton/of ha (24-54%), sunflower - from 0,28 to 1,14 ton/of ha (21-84%). The maximal productivity a winter wheat formed on black steam and sunflower at sowing 15.10., on a predecessor winter wheat at sowing 05.10. As compared to control (by the generally accepted term of sowing 25.09) the productivity of winter wheat increased depending on a predecessor on a 0,66-1,02 ton/of ha (17-44%). Reduction of the productivity from worsening of predecessor most ponderable was at sowing a 15.09 - 0,34 ton/of ha (15%) on a sunflower and 05.09 on a 0,65 ton/of ha (22%) on a stubble predecessor. Winter-annual triricale formed the greatest productivity on all three predecessors 15.10. Decline of harvest from worsening of predecessor most ponderable was at sowing a 25.10 - 1,12 ton/of ha (34%) on stubble, and also on a sunflower on a 1,13 ton/of ha (50%). The least a prime price of a 1 ton of grain was on the terms of sowing of October, 5-15, the increase of index happened at sowing 05.09; 25.10. Product Description popup.authors Авраменко М.О.
