Effect of plant density and fertilizers on the formation of productivity of sunflower hybrids grown under the conditions of Southern Ukraine
Journal Title: «Таврійський науковий вісник» - Year 2016, Vol 96, Issue
Abstract
According to the results of field research, it is found that when sunflower is grown on dark chestnut soils under rainfed conditions of Southern Ukraine, the highest yield at a level of 23-25 c/ha of seeds is formed by the Megasan hybrid. Plant density should be adjusted depending on the genetic potential of hybrids. Thus, for hybrids Megasan and Yason optimum stand density is 50 thousand/ha, and for hybrid Darii – 40 thousand/ha. The application of complex fertilizers provides a 10.7-20.9% yield increase and improves the quality of seeds, complex fertilizer Master having the highest efficiency
