THE IMPACT OF CROP DENSITY AND SOWING TIME ON THE YIELD STRUCTURE OF GRAIN SORGHUM HYBRIDS

Abstract

Nowadays, Ukraine experiences a real sorghum boom since the extreme draught-resistance, high yielding capacity and stably increasing world demand for sorghum make this crop very perspective for domestic agrarians. Thus, special significance is ascribed to the research on developing basic techniques of growing grain sorghum in the southern region of Ukraine. The field research dealt with the following factors and their variants: the grain sorghum hybrids (Sontsedar, Praim, Burhho, Sprynt W, Dash-Е and Tarhho), the sowing density and times. The maximum grain productivity was achieved by the hybrid Dash-E under the early sowing time and the crop stand density of 180 thousand pieces per hectare – 6,69 t/ha, and the hybrid Sontsedar under the density of 140 thousand pieces per hectare – 6,54 t/ha. The leader under the late sowing time was the hybrid Dash-Е with the yield of 3,96 t/ha under the crop stand density of 180 and 220 thousand pieces per hectare. Other hybrids had considerably lower yields. The prospects of sorghum crops will look good and they will be economically profitable in Ukraine, if the cultivation of these crops is supported with scientific advances – technologies and new highly productive varieties and hybrids. Nowadays, the cultivation of grain sorghum has great potential and requires a thorough study.
