Effectiveness of Assessment of Agroecological Competence of Arid Lands Under Conditions of Dark Gray Soils

Abstract

Currently, as a result of socio-economic and geopolitical changes observed in the world as a result of the expansion of urban areas, the complex urbanization process is increasing day by day. As a result of climate changes and other negative effects, fertile land is leaving agricultural circulation every year. Cereals and leguminous-cereal products form the main part of the food diet of the world's population, and these products are mainly grown in irrigated and semiarid lands. The high yield from agriculture on dry land is not satisfactory. Today, it is urgent to increase the efficiency of the use of existing dry land. Field experiments were conducted in the Shakhrisabz district of the Kashkadarya region. In assessing the bioclimatic potential (BCP) of the area, it was calculated according to the formula for assessing the bioclimatic potential of the area proposed by D. I. Shashko. Kashkadarya region is divided into three regions according to its natural characteristics: plain region, hilly region, foothills, and mountain region, BCP by region from 1.02 to 1.05, from 1.16 to 1.28, from 1.78 to 2.0, respectively. In addition to the method used in the assessment of the agroecological potential of the region, it is proposed that a correction factor for the region's water supply be introduced.
