Experience of growing soybeans (Glycine max (L) merryll) on irrigation in the unstable moisture zone of the Stavropol Territory

Abstract

To obtain a stable harvest of high quality grain, Agrosakhar LLC, located in the Stavropol Territory, used soybean growing technology, which included: the use of modern energy and resource-saving equipment for soil cultivation, sowing and harvesting, cultivation of adapted varieties bred in Russia and Canada - Selecta 302, Vilana, Furio, Kofu, Kyoto, Kanata; introduction of complex fertilizer - azophoska for main soil cultivation, pre-sowing seed treatment with a fungicidal dressing agent Delit Pro and the inoculant Highcoat Super Soy. The system of protective measures included a combination of agrotechnical measures using chemical plant protection products based on monitoring of harmful objects. To combat monocotyledonous and dicotyledonous species of weeds, sowing was treated with Pledge herbicide before germination, followed by a tank mixture of herbicides Bazagran with Harmony in the phase of the first true leaf in soybean plants. The use of the fungicide Akanto Plus together with Karate Zeon and Ampligo Plus ensured effective protection of soybean plants from diseases and pests during the growing season. The technology used for growing soybeans on the farm enables you to consistently get a large and high-quality grain yield. The maximum yield of 2.92 t/ha was obtained by sowing the Kofu variety using the developed cultivation technology. On average, the yield of protein amounted to 0.98, and vegetable fat amounted to 0.59 t/ha. The profitability of soybean grain production on the farm using this cultivation technology is 44.2%.
