To improve ecologically safe and energy-saving systems of crop fertilization in crop rotation with a short rotation depending on the ratio of organic and mineral fertilizers, leaving the non-marketable part of the crop and using intermediate crops

popup.description2

As a result of the conducted research, baseline information has been obtained for improving environmentally safe and energy-efficient fertilization systems in short rotation crop rotation using mineral fertilizers, by-products, and green manure for fertilization. According to the research findings, optimal conditions for the growth and development of plants were provided by a fertilization system that included leaving the by-products of the predecessor, applying mineral fertilizers at a dose of N53P54K54 active ingredient on average across the rotation, and fertilizing the sowing. This system ensured a chickpea yield of 2.47 t/ha, winter wheat yield of 5.39 t/ha, corn yield of 5.70 t/ha; grain units – 5.7 t; fodder units – 7.82 t; digestible protein – 0.59 t; and fodder protein units – 6.84 t. It was determined that the highest net income was obtained by using by-products + N10 for each ton of by-products, application of mineral fertilizers and fertilization with N10. With the use of these elements of technology, the net profit was maximized, amounting to 24.9 thousand UAH/ha, with a production profitability of 88.3%.
