Effects of terms and norms of biostimulator application on local peanut yield and seed quality

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 N 150 P 150 K 100 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.
