Sowing qualities and formation of yield of red fescue depending on foliar fertilizing

Abstract

The article presents the data of a scientific research aimed at increasing the seed productivity of the red fescue by optimizing the conditions of its nutrition at the critical phases of growth and development. It is established that foliar dressing in the phase of stem elongation of the red fescue of Ayra variety with the growth regulator “Amino Viks” (0.5 kg / ha) in combination with carbamide (5 kg/ ha) against the background of the basic fertilizer (N60,P45, K45) in the spring at the beginning of aftergrowing of seed sowings enable the formation of maximum productive plant stand (681 pieces / m2), the largest number of seeds on 10 shoots (945 pieces), the mass of 1000 seeds (1.22g). This led to the formation of seed productivity of 480 kg/ha, which is 12 kg/ha higher in comparison with the N60 background and 164 kg/ha higher in comparison with the unfertilized plots.
