Ecological effectiveness of biological products depending on the doses of mineral fertilizer in the cultivation of winter wheat of the Utkir variety in the soil conditions of the Republic of Karakalpakstan

As it is known, the high yield of winter wheat grain determines the availability of this production, which largely depends on soil and climatic conditions, types of agricultural machinery and the purchase price of mineral fertilizers. To date, farms in the Republic of Karakalpakstan are feeling the financial burden of purchasing mineral nutrition. Since its cost significantly affects the cost of production and, ultimately, the profitability of the farm. To solve the problem, a scientific search is needed for low-cost methods that increase grain yields to cover the significant costs of cultivating new varieties of winter wheat. In recent years, farms have been using various biological products that stimulate the growth, development and increase the yield of winter wheat. According to the researchers, seed treatment and additional fertilization through leaves helps to activate the growth and development of plants, increases their resistance to various stresses and allows them to form crops with optimal plant density, but at the same time it is an addition to the basic nutrition, not its replacement. Based on this, we can conclude that for a region with extreme agriculture, this technique is promising and relevant, but little studied and requires additional research.
