FERTILIZER OF COTTON FERTILIZER ON SERROZEM

Abstract

With regard to the arid conditions of the Turkestan region, the mechanisms of plant nutrition and responsiveness to fertilizer (NPK), water were studied and the influence on the rational use of mineral fertilizers and the water regime on the physiological processes and yields of the new, regionalized cotton variety Maktaaral-4011 was revealed. In conditions of slightly saline soils with relatively insignificant (180-200 cm) bedding of the level of mineralized groundwater for the cotton of the variety Maktaaral-4011, the optimal irrigation regime is the 01-1 irrigation scheme, i.e. one watering in the flowering phase, the second in the fruiting-ripening phase with a watering rate of 1200 m3 / ha.
