APPLICATION OF THE TECHNOLOGY OF DRIP IRRIGATION AT THE IRRIGATION OF THE COTTON

The article discusses the use of drip irrigation in the alluvial-meadow soils of the Khorezm Oasis with a pre-irrigation humidity of 70-80-60% of the marginal field moisture capacity, with watering in 4 replications according to the scheme 0-4-0. In the phase of sprouting and flowering of cotton, irrigation was not carried out; in the phase of flowering and fruit formation, four irrigations were carried out with norms of 616–651 m3/ha, the irrigation rate was 2521–2537 m3/ha or 1594–1633 m3/ha less than the control variant, which allowed save irrigation water. The article also presents the results of experiments on the study of this irrigation technology and the effect of drip irrigation on the growth, development and yield of cotton
