Abstract

In this article, the analysis of the field experiments conducted in the Tashkent province, which was aimed at improving the technology of high-quality production, and economic efficiency of peanuts in the conditions of the typical gray soil and climate, was given. In the field experiments, the effect of Microzym-2 biostimulator on growth, development, yield elements, yield and seed quality of local peanut varieties “Salomat” (standard) and “Mumtoz” was studied. Accordingly, before sowing of peanut seeds, the biostimulator Microzym-2 was applied at a rate of 30 l/t, as result the yield of legumes was 1.4 t/ha higher in “Salomat” (standard) and 1.1 t/ha higher in the class “Mumtoz” than in the control variant (11.7 t/ha). When peanut varieties were supplemented with mineral fertilizers N₁₅₀P₁₅₀K₁₀₀ kg/ha, and treated with Microzym-2 biostimulator before the sowing and during the flowering periods, 29.3 q/ha of “Salomat” variety and 33.2 q/ha of “Mumtoz” harvest were obtained. It was found that Microzym-2 biostimulator in sowing peanuts was cost-effective.
