Abstract The results of research on the study of the influence of soil processing systems and fertilizer using co-product for sown clogs and the yield of agricultural plants in a short-growing crop rotation are given. The influence of soil processing systems and fertilizer using co-products for sown clogs and the yield of agricultural plants in a short-live crop rotation is investigated. It has been established that on dark gray soil use in crop rotation of unifituted soil treatment systems contributes to an increase in the level of sown clogging (barley of the corn on grain at 1.4–1.6, wheat winter of winter of winter in 1.4–1.8 times) Due to the accumulation of the main amount of weed seeds in the upper soil layer. The system of fertilizer with by-products at the beginning of the vegetation of plants stimulates the germination of weeds. On average, over the years of research, the abundance of weeds in cropping crops at the beginning of vegetation when using unifituted soil treatment systems was 213–362 pcs/m2, dismissal – 94–108 pcs/m2, and before harvesting was noted a decrease in clogging, respectively, 29–57 pcs/m2, 10–13 pcs/m2. The air-dry weight of the weeds of the highest was with surface soil processing using co-product fertilizer (81.3–85.4 g/m2) relatively with dumping soil treatment (21.7–23.3 g/m2). The highest grain grain of wheat winter – 6.91 and 6.50, corn – 11.47 and 11.74, barley of the yarn – 5.37 and 5.13 and the rape of winter – 3.08 and 3.19 t/ha received when Discalled by 20–22 cm and shallow 10–12 cm soil processing system. With a 6–8 cm surface, the yields of crops decreased by 1.45, 3.66, 1.69 and 0.31 t/ha correspond to plants. A significant reason for reducing plant yields in versions with unifituted soil treatment systems served as a clogging factor, because the level here was higher than when the soil processing.
