BIOENERGETICS ESTIMATION OF LONGTIME FERTILIZERS’ APPLICATION IN THE CROP ROTATION
06.00.00 Agricultural sciences
DescriptionThe influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of winter wheat varieties was investigated and bioenergetics estimation was given. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten field crop rotation: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content (0-30sm), depending on the power of nutrition backgrounds in the arable soil layer. It was found that the selection of predecessors and the differentiated application of mineral fertilizers ensure stable high yields of grain and they exceed the varieties without fertilizers by 40-79%. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. A strong correlation between yield and agronomic methods was determined. The most effective predecessor for the wheat cultivation by the turnover of furrow slice is sainfoin, peas and wheat. More labor intensive and energy-consuming predecessors are grain maize and sugar beet
