Abstract

When cultivating crops in arid conditions, special importance is attached to soil cultivation systems aimed at eliminating the deficiency of soil moisture. The main purpose of soil cultivation is to create an optimal soil structure, which is a multiphase system of solid, liquid and gaseous components that form soil fertility with a subsequent effect on the yield of agricultural crops. Various soil cultivation systems are used to form a favorable soil structure. The conservative cultivation system consists in the minimum impact on the soil (usually direct sowing) and with the preservation of plant residues on its surface. The relevance of the study is to identify the most effective system of soil cultivation. The study was carried out under the conditions of many years of stationary experience in legume crop rotation for 5 years. It was revealed that the conservative system of soil cultivation is effective and surpasses the traditional one in the following indicators: soil moisture is more by 14.2%; the soil temperature is 2.6% lower; soil density is 3.48% higher. A stable increase in yield was also revealed: for winter wheat by 6.62%, for spring barley by 8.09%, for peas by 13.95% and for soybeans by 23.00%.
