THE MAIN ELEMENTS OF THE TECHNOLOGY OF SOYBEAN VARIETIES CULTIVATION ON LOW SALINE SOILS IN KHOREZM REGION, UZBEKISTAN

Abstract

The optimal timing of sowing soybean varieties on low saline soils of the Khorezm region is one of the most important agricultural practices. The material presented indicates that the land and water resources and thermal regime of the region are sufficient to ensure the growth and development and complete ripening of all soybean varieties with the highest possible efficiency. Analyzing the data obtained, it is necessary to indicate that in low saline soils of Khorazm region the best sowing dates for varieties Dustlik, Eureka 357 and Orzu are in the second decade of May. The use of rizotorphin while sowing soybean seeds leads to increased yields. Cultivated soybean varieties using rizotorphin leave on the field more crop residues, rich in nitrogen, and therefore are excellent forecrops for other agricultural plants. Preliminary salt leaching and land reclamation measures to combat negative impact of soil salinization are absolutely necessary before sowing soy.
