The variety of fodder kale “Mozgovaya zelenaya Vologodskaya” is bred at the Vologda State Agricultural Experimental Station by multi-year mass selection. The authors of the variety are M.F. Svetenko, N.A. Gvozdikova, Z.I. Britvina. High and stable yields of green mass per 1 ha were obtained in the Vologda and adjacent oblasts, the average for the years of cultivation – 559 cwt (in some years – up to 1000 cwt). Seed yield on average – 8 cwt/ha, the maximum was obtained 18 cwt/ha. Fodder kale “Mozgovaya zelenaya vologodskaya” gives a highly nutritious balanced protein fodder for farm animals. The crop has a high coefficient of nutrient digestibility, and its increased succulence contributes to better digestibility of straw, concentrates and other forages in the diet. Digestibility of green fodder and silage on average: protein – 68 and 72%, fat – 57 and 72%, fiber – 70 and 67%, nitrogen-free extractive substances – 80 and 75%, respectively. In recent years, this crop has been undeservedly forgotten in Russia. Our research is aimed at adaptation of valuable old variety of fodder kale “Mozgovaya zelenaya vologodskaya” to modern climatic and agrotechnical conditions of its cultivation for fodder purposes. In 2022 at higher temperature regime on the background of rainfall deficit the yield of green mass was obtained 44.6 t/ha. In terms of productivity and nutrition, the green mass of fodder kale variety “Mozgovaya zelenaya vologodskaya” exceeded such silage crops as corn variety “Scandinav”, pasture ryegrass. Highly nutritious green mass of fodder kale with the content of EE up to 12.2 MJ was obtained
