Influence of abiotic factors of the Middle Cis-Urals on fodder and seed productivity of bird’s-foot trefoil

Abstract

The article analyzes the influence of the abiotic factors of the Middle Cis-Urals and the age of the grass stand on the fodder and seed productivity of the bird’s-foot trefoil (Lotus corniculatus L.) Solnyshko. It was revealed that in 2-4 years of use, the yield of dry matter reaches 5.3-6.4 t/ha. At the same time, bird’s-foot is able to provide a high collection of dry matter, both in arid conditions and with excessive moisture in the growing season. Seed productivity of bird’s foot was higher in the 1st and 2nd years of use – 304 and 163 kg/ha, respectively. Arid conditions of the growing season, especially in the phase of flowering -ripening of seeds, contribute to obtaining a high yield of seeds. Of the seven years of research, conditions close to those indicated were created in 43%.
