In course of the research there was studied the combined mineral fertilizers and Phytostimophos application in cultivation of soya (Glycine hispida), vegetable beans, asparagus beans (Vigna sesquipedalis) and tomatoes (Lycopersicon esculentum). The study was realized in the conditions of the Republic of Belarus on sod-podzolic loamy soil. The main research was conducted on the pilot site in Pinsk district of Brest region in 2008–2010. Agrochemical characteristic of soil plough-layer was the following: рН КСl 5.9–6.2; Р2О5 content (0.2 М HCl) – 170–180 mg/kg; К2О (0.2 М HCl) – 220–240 mg/kg of soil; humus (0.4 М K2Cr2O7) – 1.8–2.0% (agrochemical anthropic index 0.89). Research crops were soya Pripyat, vegetable beans Belorusskie, asparagus beans Magura, tomato Omega. As the result of the realized research it was revealed that application of mineral fertilizers and Phytostimophos ensured high agro-economic efficiency. In process of soya of Pripyat variety cultivation, the crop yield was 26.1 c/ha, crop yield gain – 13.7 c/ha, crude protein content – 29.0%, profitability – 314%. In process of asparagus beans of Magura variety cultivation, the bean crop yield in a phase of technologic maturity was 220.1 c/hа, crop yield gain – 24.3 c/ha, crude protein content – 12.3%, profitability – 86%. In process of vegetable beans of Belorusskie variety cultivation, the seed crop yield was 102.7 c/ha, crop yield gain – 6.5 c/ha, crude protein content – 16.9%, profitability – 138%. In process of tomato of Omega variety cultivation, the fruit crop yield was 357.0 c/ha, crop yield gain – 101.0 c/ha, crude protein content – 7.3%, profitability – 481%. The application of bacterial phosphate-mobilizing preparation Phytostimophos for these crops growing helped to decrease the dose of mineral phosphorus fertilizers by 20 kg/ha of active ingredient.
