Mineral fertilizers as a factor in managing the productivity potential of the green mass of the seeded bluegrass herbage mixture, in conditions of superficially improved central floodplain

In the period from 2019 to 2021, in the conditions of the central meadow of the Iput River in the Novozybkovsky district of the Bryansk region, studies were conducted on the possibility of managing the productivity of a seeded bluegrass herbage mixture using mineral fertilizers. As a result of the research, it was found that the best conditions for obtaining consistently high yields of the green mass of the first and second mowing when cultivating a seeded bluegrass mixture are the use of mineral fertilizers in doses of N60P60K60 and N60K60, respectively. The maximum level of chemicalization creates the best conditions during the first and second mowing periods to adapt to changing environmental conditions. Our research substantiates the possibility of managing the yield of bluegrass herbage mixture in the conditions of the central floodplain of the Iput River in the Non-Chernozem zone of the Russian Federation through the selection of various types, doses, and combinations of nutrients in fertilizers under variable environmental conditions.
