Yield and quality of grain of winter varieties wheat when using agrochemicals in the conditions of the Republic of Dagestan

The results of studying the influence of agrochemicals on the growth, development, yield and quality of winter soft wheat varieties in the conditions of the flat irrigated zone of the Republic of Dagestan are presented. Research has established that pre-sowing seed treatment with Potassium Humate Prompter and foliar fertilizing with Biostim grain (agricultural chemicals from Shchelkovo Agrokhim JSC) had a significant impact on plant growth and the development of the root system of winter wheat, photosynthetic activity of crops, efficiency of irrigation water use and productivity. The Carolina 5 variety exhibits maximum yield with a combination of pre-sowing seed treatment and three foliar applications during the tillering, booting and heading phases, which ensures a yield of 6.69 t/ha of grain while improving its quality. Calculation of adaptability parameters showed that the use of grain Biostim improves genetic flexibility, general adaptive capacity, ecological plasticity and adaptability coefficient, and therefore the Carolina 5 variety is of practical interest in terms of variety replacement of zoned varieties of winter wheat for the irrigated zone of the region.
