The most important task of agriculture at the present stage of its development is to increase the production of high-quality crop products. In this regard, the development of technological methods for the use of local raw materials in order to increase the yield and quality of crop products is relevant. The purpose of the research was to study the aftereffect of urban sewage sludge and their combinations with zeolite-containing agro-ore on crop yields and the quality of crop production in the conditions of the forest-steppe of the Middle Volga region. It has been established that the complex aftereffect of increased norms of urban sewage sludge (160 and 180 t/ha) and zeolite-containing agricultural ore increased the yield of Jackpot peas in 2019 by 1.12-1.14 t/ha, or by 48.9-49.8%, protein content in pea grain by 2.3-2.7%.
