ts / ha, additional yield was 433 ts / ha, grain yield was 98 ts / ha, additional yield was 65 ts / ha.
In summary, both silage and grain yields declined sharply when corn herbicides were not used at all. Depending on the structure of the grain, it showed low yields. The reason can be said to be an overgrowth of weeds, as mentioned above.
Highest results Super stomp, 33% em.k. Determined when applied to 3 l / ha. FAO 190 early maturing variety, silage yield 430 ts / ha, grain yield 63 ts / ha compared to control, Kubanskaya konservnaya - 148 fast- ripening varieties, silage yield was 427 ts / ha and grain yield was 64 ts / ha more than the control.
with FAO 190 early ripening variety, Kubanskaya konservnaya - 148 early ripening varieties, high yield was found when using Elyumis105 1 l / ha during the growing season, ie silage yield was 440 ts / ha, grain yield was 67 ts / ha compared to control. Kubanskaya konservnaya - 148 fast- ripening varieties, silage yield is 437 ts / ha, grain yield is 66 ts / ha. increased i.
Yields also did not show excessively high when herbicides were unreasonably increased, on the contrary, a significant decrease was observed. Yields showed high results in proportion to both varieties when herbicides were applied during the growing season.
