ЭФФЕКТИВНОСТЬ БИОПРЕПАРАТА БИОСТИМ НА ПОСЕВАХ КУКУРУЗЫ РОСС 140 СВ

Abstract

The studies were conducted to study the effect of mineral fertilizers and the certified biopreparation Biostim Corn on the growth of the Ross 140 SV corn hybrid under irrigation. The field experiment was carried out in the conditions of the Republic of Tatarstan in 2021-2023. The object of the study was the Ross 140 SV hybrid zoned in the seventh region (Middle Volga region), bred by Krasnodar Research Institute of Agriculture named after P.P.Lukyanenko. In the experiment, various schemes for using the Biostim Corn preparation separately and in combination with Maksim Gold fungicide were studied. The use of Biostim Corn as a seed dressing before sowing at a dose of 2 l/t helps to increase the productivity of green mass. Its combined use with Maksim Gold seed dressing is even more effective. Against the background of the application of the calculated rates of mineral fertilizers, this ensures the formation of an additional 1.8 t/ha of green mass and an excess of the planned yield of 50 t/ha. Replacing Maksim Gold seed dressing with Biostim Corn increases the efficiency of using mineral fertilizers and foliar feeding. The profitability of green mass production of corn in the variant with the integrated use of agrochemicals is 73.3%, the conditional net income is 33.9 thousand rubles/ha, the cost of 1000 feed units is 4.6 thousand rubles. The use of the biopreparation Biostim Corn in the technology of cultivating the hybrid crop Ross 140 SV on irrigation allows you to improve the quality of seeds, increase the productivity of green mass and reduce the cost.
