Abstract
Among the methods of cultivation that increase the productivity of crops, a prominent role is assigned to crop rotation. In a properly constructed crop rotation, the efficiency of all agrotechnical methods aimed at improving the use of land increases, the biological needs of crops are satisfied, the rational use of technology is achieved, and the cost of production is reduced [1]. The soils are low in nitrogen, medium in phosphorus and high in potassium. The humus content is 1.2–2.0%, pH = 7–8. Studies have shown that green manure (sweet clover, oats, phacelia) have a positive effect on the balance of organic matter. The negative balance of organic matter is noted for pure steam. The stock of productive moisture in the 0–0.3 cm soil layer varied from 4.1 to 29.5 mm for winter wheat, 28.1–32.7 mm for chickpea and 28–35.3 mm for spring barley, depending on the weather conditions. conditions and methods of biologization. On average, over three years, the highest yield was in winter wheat for a busy fallow (phacelia) and amounted to 1.0 t/ha, which depended on weather conditions. A reliable correlation was revealed for the factors of yield-precipitation; temperature; batteries, etc.
