Red fescue is one of the main components of improving cultivated pastures and hayfields and expanding their areas - it is to ensure sufficient production of grass seeds.
By its biological characteristics, red fescue refers to crops with high potential seed productivity. On the one hand, its modern varieties are capable of providing seed yield at the level of 0.5-0.7 t / ha, on the other hand, for red fescue, a significant dependence of the level of seed productivity on environmental factors and agrotechnical conditions of cultivation, in particular, the
density of the agrocenosis, moisture, light and nutrients, depending on the stages of organogenesis Foliar top dressing in the phase of emergence of red fescue varieties Aira with a growth regulator "Amino Vix" (2 kg / ha) in combination with carbamide (5 kg / ha) against the background of the main fertilizer (N60P45K45) in the spring at the beginning of regrowth of seed crops contributed to the formation of the maximum productive stand (681 pcs / m2), 1000 seeds weight (1.20 g), which led to the formation of seed productivity of 480 kg / ha, this is 12 kg / ha higher in comparison with the background N60 and 164 kg / ha higher in comparison with unfertilized plots
Проведение внекорневой подкормки в фазу выхода в трубку овсяницы красной сорта Айра регулятором роста
«Амино Викс» (2 кг/га) в сочетании с карбамідом (5 кг/га) на фоне основного удобрения (N60P45K45) весной в начале
отрастания семенных посевов способствовало формированию максимального продуктивного стеблестоя (681 шт./м2), массы
1000 семян (1,20 г), что обусловило формирование семенной продуктивности 480 кг/га, это на 12 кг/га выше в сравнении с
фоном N60 и на 164 кг/га выше в сравнении с неудобренными делянками.
