Abstract
In this paper, the approach to reduce the risk of irrigation erosion in the irrigated areas where ‘Andijan 37’ and ‘Namangan 77’ varieties of cotton were sowed, in which the topsoil is formed by typical gray soils and which are vulnerable to erosion, was validated. In cotton irrigation, while watering with a device with a 15 mm of irrigation hollow, the cotton water-demand was improved and an optimal and favorable condition to uptake the potential moisture and nutrient for cotton breeding was created. This enabled to harvest 3.6 quintals more cotton yield per ha in contrast to the usual condition, to gain the net profit accounted for 700,309 sums per ha, and to improve the profitability by 38%.
