Abstract
The article shows the results of studies on the productivity, economic and energy efficiency of cultivation of sunflower depending on the hybrid composition, stand density of plants and fertilizing compound fertilizers. The aim of this work was to establish performance, economic and energy efficiency technologies sunflower cultivation in the South of Ukraine. According to the research found that when growing sunflower on dark chestnut soils without irrigation in Southern Ukraine the highest yield at 2,3-2,5 t/ha seed of hybrid forms Megasan. When growing studied culture density stand of plants should be adjusted depending on the genetic potential of hybrids. Thus, for hybrids Megasan and Jason optimum stand density is 50 thousand/ha for hybrid Darius – 40 thousand/ha. Processing of sunflower crops provides complex fertilizers increase yield at 10.7-20.9% and improves the quality of seeds, with the greatest efficiency is characterized by complex fertilizer Master. Growing sunflower seeds were cost-effective in all versions of the experiment, indicators of production costs were characterized by stability, and net income and profitability had significant fluctuations. The use of any and all complex fertilizers caused significant (in 20.2-35.1%) increase in net profit in growing hybrid seeds Megasan, Jason and Darius. Energy efficiency ratio reached its highest level in the variant with hybrid Megasan in the formation of standing plant density 40-60 thousand/ha of fertilizer feeding.
