The aim of the research is to study the effect and aftereffect of chicken manure on the productivity of spring wheat in the forest-steppe of Western Siberia. The research was carried out at the experimental field and the Department of Agrochemistry and soil science of Omsk state university in 2015-2018 with spring wheat varieties Duet on meadow-chernozem soil. The content in the soil layer 0-20 cm before sowing N-NO3-2,32-7,10, P2O5-90-125, K2O-250-360 mg / kg. In the research all applications of manure resulted in a fair increase in grain yield of spring wheat both in action and in aftereffect of the first year. The most effective doses of manure in the first year of action-16 and 20 t / ha-grain additions were respectively 0.74 and 0.82 t / ha or 29.9 and 31.5 to control. In the first year of aftereffect from doses of 12-20 t/ha, the increase in yield was 0.63-0.66 t / ha (27.15-28.44 to the variant without the use of manure). The maximum amount of crude protein contained in the grain at a dose of 20 t / ha-18.5 (control 17.5). The experiments found: payback manure additional yield, the coefficients of the action of manure on soil chemistry, nitrogen of current nitrification, the cost of batteries to create 1 t of grain, number of batteries made with 1 t of manure, the utilization of elements from the soil and litter.
