The article provides information on the effect of leaf feeding on cotton yield and technological quality indicators of fiber by means of a suspension prepared on the basis of urea during the period of mating and flowering of 2-3 chin leaves, depending on different feeding norms. Against the background of application of mineral fertilizers N-200, P2O5-140, K2O -100 kg / ha in cotton, the highest cotton yield is 7.0 kg / ha in the period of 2-3 leaves, 9.0 kg / ha in the period of weeding and at the beginning of the flowering period. The urea-based suspension at a rate of 11.0 kg / ha was obtained from the leaf-fed variant and amounted to 37.5 centner / ha. Against the background of application of mineral fertilizers N-250, P2O5-175, K2O -125 kg / ha, the highest yield of cotton is 5.0 kg / ha in the period of 2-3 leaves, 7.0 kg / ha in the period of weeding and at the beginning of the flowering period. The urea-based suspension at a rate of 9.0 kg / ha was obtained from the leaf-fed variant and amounted to 38.9 centner / ha. The use of urea-based suspension in cotton against the background of different standards of mineral fertilizers has a different effect on the technological quality of cotton fiber, fiber yield by 0.2-0.6%, weight of 1000 seeds 0.4-2.9 g. e, and the fiber length was 0.3–0.8 mm higher.
