| Summary: | Taking into account plant biological properties, soil properties, soil-climatic conditions, and fertilizer properties, the development of the optimal rate, duration, and methods of application of suspensions made from mineral fertilizers, the optimization of the soil nutrient environment, the formation of the necessary chemical composition in the plant, and scientific research aimed at managing plant nutrition, special attention is paid. In Uzbekistan, scientific research aimed at evaluating the effective use of mineral fertilizers in increasing the yield of agricultural crops, including wheat, is being conducted, and certain results are being achieved. It is critical to develop an optimal system of using mineral fertilizers to ensure the cultivation of high-quality grain crops from autumn wheat varieties in the irrigated typical gray soils of the Tashkent province, as well as to determine the nutrient environment formed in the soil during specific periods of autumn wheat development phases and the amount and ratio of nutrients in the plant. Fertilizer is an effective and fast-acting factor that increases the quality of the crop. Therefore, it is important to develop the optimal norm for using a suspension of mineral fertilizers in foliar feeding, taking into account the characteristics of the soil and variety, to grow a high-quality grain crop from wheat, as well as to study the effect of these norms on the growth development, seedling thickness, grain yield, and quality of autumn wheat.
