EFFECT OF SOIL TYPES, SALINITY AND MOISTURE LEVELS ON COTTON PRODUCTIVITY

The following article deals with the data obtained as a result of studying the effect of soil types, salinity and moisture levels on cotton productivity in the conditions of irrigated and saline soils of the Bukhara oasis. In the conditions of ancient irrigated meadow-alluvial, brownish-brown and newly developed desert sandy soils, the growth rate, expansion of leaf surfaces and various changes in the soft productivity of photosynthesis in the crop cross-section depend on the strength of environmental stressors and biological features of varieties.
