SORGHUM PRODUCTIVITY IN THEMIDDLE VOLGAFORESTS

For the first time the most highly productive varieties of sugar sorghum adapted to the conditions of the Middle Volga region were studied and revealed; the most effective chemical and biological preparations providing at different levels of mineral nutrition formation of green mass of 40 t/ha at minimum production costs with high economic and energy indicators were established.Recommended varieties (Chaika and Flagman), calculated doses of mineral fertilizers, chemical (Forpost) and biological (Phytotrix (f.f.) drugs that ensure the productivity of sugar sorghum in achieving harvesting ripeness (41.9 and 42.9 t / ha) with high quality indicators, which is confirmed by production testing conducted in the collective farm "Rodina" Alexeyevsky municipal district of the Republic of Tatarstan.
