Abstract: Data are presented on economically valuable indicators (green mass yield, air dry matter, plant leafiness, collection of air dry leaf matter) of the horned bridal bird in different phases of mowing. The purpose of the work is to compare the varieties of the horned bird for different phases of mowing and select the best in fodder productivity for a complex of economically useful traits. Studies were conducted from 2016–2018 according to generally accepted methods in breeding crop rotation and laboratory conditions, based on the Smolensk Institute of agriculture (ex Smolensk GOSHOS). The soil of the turf area is light loamy, medium acid, low in humus, high – mobile phosphorus, and medium mobile – potassium. Terms of mowing periods and yield distribution were determined by the climatic conditions of the Smolensk region. The best indicators of the variety show in the second and third phases (the beginning is mass flowering). The yield of air-dry matter in the average variety Smolensk 1 was 37.8–39.1 с/ha, green mass – 156.4–191.6 c/ha, collection of air-dry matter of leaves – 18.3–23.6 q/ha, foliarity – 51.1–53.9%, respectively, from the variety Sunny, 36.5–38.6 q/ha, 137.9–166,9 c/ha and 18.2–20.8 c/ha, 47.8–51.2 %. Mowing at an earlier date (budding) leads to a decrease in feed productivity by 35%. Evaluating fodder qualities, the Smolensky variety 1, in contrast to Sunny, is characterized by the highest productivity, which averaged in the third phase (mass flowering) 191.6 c/ha, air-dry substance – 39.1 c/ha, leaves yield – 23.6 c/ha, foliage – 53.9%. This variety was introduced in 1979 into the State Register of Breeding Achievements of the Russian Federation and is most environmentally adapted to the conditions of the Smolensk Region.
