Abstract. The purpose of the conducted research was to study the botanical composition, productivity and nutritional value of agrophytocenoses created on the basis of a rare annual crop of Sudan grass in the conditions of the Vologda region. Methods. The study was conducted in 2023–2024 and focused on the cultivation of annual crops for forage purposes, both in single-species and mixed crops. The location is the experimental field of the North-West Research Institute of the Vologda Scientific Center of the Russian Academy of Sciences. The field experiment scheme included 10 options, in 3-fold replication. The area of the accounting plot was 14 m2 . The following varieties of annual crops were selected for the formation of crops: Sudan grass of the Chishminskaya rannyaya variety, field pea Vologda usaty, spring vetch Lgovskaya-22, spring rape Bison and oats Yakov. The soil cultivation system complies with generally accepted regional standards. Scientific novelty. For the first time in the conditions of the Vologda region, the best grain mixtures are identified, created on the basis of a rare annual crop of Sudan grass in mono- and bi-crops with peas, vetch, spring rape and oats to obtain stable yields of green mass. Results. On average, the following mixtures showed the same dry matter yield per season as the control: 60 % Sudan grass + 40 % field pea (2), 60 % Sudan grass + 40 % spring vetch (4), 50 % Sudan grass + 30 % field pea + 20 % oats (7), and 40 % Sudan grass + 20 % field pea + 20 % spring vetch + 20 % oats (10). The remaining mixtures showed lower yields than the control. During the season, 3.8–6.0 thousand feed units, 0.63–1.06 tons of crude protein were obtained from 1 ha, and the exchange energy yield was 49.8–75.9 GJ. Scope: agricultural enterprises of the Vologda region.
Keywords: field peas, spring vetch, spring rape, oats, Sudan grass, productivity and nutrition of forage
