EFFECT OF MINERAL FERTILIZERS AND UREA FERTILIZER SUSPENSION NORMSS ON YIELD OF OIL SUNFLOWER

Abstract

This article presents data on the effect of suspension application
of urea fertilizer at different norms on the yield of Dilbar sunflower variety on the
background of mineral fertilizers. According to it, in both backgrounds where the
norm of mineral fertilizers N-150, P-75, K-100 and N-200, P-125, K-150 kg/ha
was used, the plant's 2 -3 3.0, 5.0, 7.0 kg/ha in the period of true leaves, 5.0, 7.0
9.0 kg/ha in the period of star formation and 7.0, 9.0, 11 at the beginning of the
flowering, It was found that the yield was higher in the variants fed with the
suspension prepared on the basis of urea
