Regulation of the water balance of the cotton varieties under salting conditions

The article provides information on water balance management in saline conditions of medium-fiber cotton varieties. All physiological parameters studied with increasing soil salinity vary in both species depending on biological and individual characteristics of the varieties, and the salinity of the Bukhara-8 variety against the S-6524 variety is scientifically based. During the transpiration, the water potential of the leaf and the pressure in the kselema are reduced due to water loss. The transpiration of water inside the leaves is largely controlled by the oral cavity. On the basis of both indicators, soil moisture content was maintained at 70% of total moisture content (T.N.S.). In the bottles, different levels of soil salinity were formed by chlorine ion depending on the air dried mass of the soil. Prior to field experiments, saline areas of varying salinity were identified. In both varieties, the intensity of transpiration was lower in the control and experimental variants in the morning hours, higher in the afternoon, and again in the evening. The negative effects of salts have changed the water balance of the cotton and limit the water availability of plants. In saline soils a deep and sufficient analysis of the water balance of plants and their management and water supply is required. According to the obtained data, the cost of day and residual water shortages was higher for S-6524 grade and lower for Bukhara-8 grade. In defining salinity resistance of agricultural plants, it is also recommended to study water deficiency in leaves.
