The Effectiveness of Innovative Technologies in the Cultivation of New Hybrids of Corn

Abstract

This article describes the resuls of scientific research on optimizing the sowing rate and bush thickness, which are the main elemens of the technology of cultivation of new hybrids of medium-ripe maize "Uzbekistan 601 ЕСВ" and medium-early "Karasuv 350AMB" in meadow soils in the middle of the Zarafshan valley. The article examines the growth, development, yield, and sowing thickness of new hybrids “Uzbekistan 601 ЕСВ” and middle-ripening “Karasuv 350AMB” included in the State Register of Corn in the Republic of Uzbekistan and shows that the optimal sowing rate is 75,000 seeds / ha. productivity 80.1; 65.7 s / ha The resuls of the study show that with the increase of sowing norms, the silage mass yield increases and the sowing norm (st) is 55 thousand seeds / ha. 47.1 tons, replanted Karasuv 350 AMB medium-early hybrid hybrid 24.5 respectively; A silage mass yield of 39.2 t / ha was obtained. Data on feed unit consumption per hectare and the amount of protein digested are also described.
