The existing technology of soybean cultivation with mandatory tillage is quite expensive, when up to 30 % or more of the total costs are spent on preparing the soil for sowing, and most of them are spent on fuel and lubricants, which are becoming more expensive every year. The purpose of the research is to determine the effect of the technology recommended by scientific institutions and the technology of soybean cultivation without tillage with the introduction of various doses of mineral fertilizers on its yield and agrophysical properties of ordinary chernozem in the zone of unstable moisture in the Central Ciscaucasia. The influence of soybean cultivation technology without tillage, depending on the doses of mineral fertilizers, on its growth, development, yield and agrophysical, chemical and biological properties of ordinary chernozem has been studied, and an economic assessment of the studied agricultural practices has been given. Cultivation technologies and applied fertilizers did not significantly affect the quality of soybean seeds. The oil content in soybean seeds for both technologies and all doses of fertilizer application on average over the years of research was in the range of 19,8–20,3 %, protein for the same variants of the experiment contained 41,3–41,7 %, and all differences in these indicators were not statistically significant. When cultivating soybeans using No-till technology the cost of purchasing and applying a continuous herbicide increases by 1280 rubles/ha or by 49,4 % in relation to the recommended technology. However, the recommended technology significantly increases production costs for the purchase of fuel and lubricants – by 3,276 rubles/ha or 232,0 %, the wage fund by 824 rubles/ha or 93,4 %, depreciation and repair of equipment by 891 rubles/ha or 47,0 %. Thus, the biggest economic efficiency has been obtained when using the technology of soybean cultivation without tillage and without applying mineral fertilizers.
