Abstract
The article studies the effectiveness of using mineral fertilizers, growth stimulants and bacterial preparations in the cultivating millet technology. The research was carried out in 2021–2023 on the experimental field of the Kabardino-Balkarian Scientific Research Institute of Agriculture, which located in the steppe zone of the Kabardino-Balkarian Republic. The object of study is the mid-late millet variety Kavkazskie Zori, bred by Kabardino-Balkarian Research Institute of Agriculture. Inoculation of seeds with Rizoagrin (Agrobacterium radiobacter) and Azophyte (Azotobacter vinelandii) was carried out on the day of sowing, exogenous spraying of plants with growth stimulants Mival Agro (10 g/ha), MS-extra (0.5 kg/ha) – in the three-leaf phase. Treatment of seeds with biological preparations Rizoagrin and Azofit increases field germination by 8.9 and 5.3%, respectively, relative to the control. They also have a positive effecton the preservation of plants for harvesting. The usage of biological products provides an increase in the yield of millet by 0.38–0.54 t/hacompared to the control, fertilizers – 0.64 t/ha, growth stimulants – 0.27–0.46 t/ha. Maximum productivity was achieved with the biological product Rizoagrin and the growth stimulator MS-extra against the background of N10P26K26 – 2.48 t/ha.
