Studied accumulation of crude protein in vegetative organs and grain and accumulation of crude fat in grain of soybean varieties of northern ecotype. The estimation of the amount of crude protein in the soy plant organs in different phases of ontogenesis in contrasting weather conditions was made. The effect of weather conditions, high-quality features and technological methods on the content of crude protein and crude fat in soybean grain was investigated. Established prevailing role of year conditions, as compared to varietal differences and elements of technology in formation of qualitative characteristics of soybean. In weakly dry conditions protein and fat content in grain is higher than in wet years. According to long term data the maximum content of crude protein in grain was observed at varieties of Lancetnaya and Krasivaya Mecha - 39,0-41,1 %, crude fat - of the Lancetnaya – 24,0 %. Established positive effect of combined use of inoculation and starting dose of mineral nitrogen N30 on increase of crude protein content in grain for varieties Mageva and Lancetnaya and potassium humate for Mezenka and Zusha
