Abstract
In the Southern Federal District, sunflower is one of the most highly productive and profitable crops. At the same time, the level of yield and quality of kernelss directly depends on the cultivation technology and applied agrochemicals. The present work considers the field trials conducted with the large-kerneled sunflower variety ‘SPK’ to identify its responsiveness to the use of amino-chelate fertilizers ‘Agrovin’, its economic and bioenergetic efficiency. The study shows that the most effective combination is a simultaneous use of amino chelate fertilizers 0.8 l/ha of ‘Agrovin Micro’+ 1 kg/ha of ‘Agrovin Universal’ in the phase of 6–8 leaves. In that case the maximum yield of seeds was obtained (2.53 t/ha with the largest share of the estimated net income of 22 922 rubles/ha and the lowest seed cost of 5940 rubles/t with 153% of profitability). Thus, the highest net energy income of 33 774 MJ/ha and 4.0 of the energy efficiency ratio (EER) were achieved.
