In the agro-climatic conditions of the Non-Chernozem zone, the grass stands of red clover allow for at least two full-fledged mowing of the fodder mass. The analysis of scientific literature and the experience of cultivating crops in the region show the possibility of obtaining three or more mowings. More intensive use of grasslands expands the possibilities of using red clover in the system of regional field forage production. The purpose is to substantiate recommendations on the selection of varieties of red clover for intensive (three–cut) grass management in the soil and climatic conditions of the south-west of the Central region. Research methods: field and laboratory. The experiment was conducted in 2022-2024 in the conditions of the experimental field of the Bryansk State Agricultural University. It was revealed that according to the growth dynamics, the varieties Kretunovsky, Krynia, Milena and Blizard were distinguished. It is noted that the varieties VIC-7, Krynia, Dayana, Milena and Blizard are suitable for earlier economic use, and the varieties Trifon, Chance, Kretunovsky and Dymkovsky can be planned to start harvesting 7-10 days later. Quite significant varietal differences in the content of absolutely dry matter in the first and subsequent mowing were found out. It has been established that in the agro-climatic conditions of gray forest soils of the Bryansk region, it is possible to use a three-cut scheme of grass management. For intensive (three-cut) use, red clover varieties Dayana, Kretunovsky, Milena and Blizard should be recommended, which form at least three mowing over a two-year period, while providing yields of over 50 t/ha of green mass and more than 11 t/ha of dry matter.
