Certain Ecophysiological Characteristics of Corn Varieties Under the Conditions of The Bukhara Region

This article presents the results of a study on the physiological characteristics of water exchange in corn varieties under varying soil moisture conditions. The findings indicate that the physiological activity and water exchange traits of the studied corn varieties differ depending on soil moisture levels and their inherent biological characteristics. Variations were observed in transpiration intensity and overall physiological responses under different moisture regimes. Under water deficit conditions, the Andijon-36 and Yangiobod varieties demonstrated higher productivity compared to other varieties. These results provide a scientific basis for identifying relatively drought-tolerant corn varieties suitable for cultivation under arid and semi-arid conditions.
