Abstract

Efficiency of mineral fertilizer use of growing sunflower hybrids is studied. Cultivar response of hybrids to basic, supplemental and preplant applications of fertilizers is estimated.
While growing  hybrid Oscil in null- fertilizer background the best results were obtained in the variant of  Р15 application at planting + (NРК)30 at the rate of  2,94 t/ha.  At the basic application of mineral fertilizers the similar results were achieved in the variants with the application of  Р15 + N30 (sod. nitre) and Р15 + (NРК)30 +0,23 and  +0,19 t/ha, grain yield increase as compared to the control, in the sowings of hybrid Vsesvit in all the variants there was an increase of grain yield from 0.20 to 0.35 t/ha/
Although while applying the fertilizers the production expenditure rises from 857,9 grn/ha in the control to 1370.6 grn/ha but net profit is also increased by 44-438 grn/ha, respectively
