The subject of research is dark gray gilded soil, winter wheat, sunflower, soybean, corn for grain, fertilization systems based on by-products, soil cultivation systems. The purpose of the work is to determine the impact of tillage and fertilization systems with the use of by-products on the economic efficiency of growing agricultural crops in short-rotation crop rotation. In the Western Polissia zone, effective systems of soil cultivation and fertilization using by-products in short-rotation crop rotation have been studied and developed, which increase the soil protection effect, reduce the negative impact of weeds in crops, improve soil fertility and increase the productivity of crop rotation crops. It was established that the volume weight of the soil in a layer of 10-20 cm increased with the use of disk tillage systems with periodic deep loosening up to 1.30 - 1.36 g/cm3 with different use of by-products. The maximum weediness during the period of germination and harvesting of crops in the crop rotation was noted on variants with disk tillage systems with different use of by-products and it was, respectively, 195 – 275 pcs./m2 and 51 – 90 pcs./m2 with a weight of 32.6 - 55.8 g. It was established that the highest grain yield of winter wheat was obtained on the option of multi-depth plowing and disking at 15-17 cm with periodic loosening, respectively - 7.18 t/ha and 7.07 t/ha. With the use of 10-12 cm discing in the tillage system with periodic loosening, the yield of winter wheat was lower than the control by 0.65 t/ha. Using multi-depth plowing and 15-17 cm discing with periodic deep loosening against the background of fertilization systems with by-products hel Product Description popup.authors Markarian Volodymyr V. popup.nrat_date 2023-12-13 Close
