This experiment aims to establish the productivity and quality of several rapeseed hybrids grown for green fodder in the region of Central Southern Bulgaria. The experiment was conducted for three years (2017-2020) in the experimental field of the Department of Plant Growing at AU Plovdiv, by the block method, in 4 replications, with a harvest plot size of 20 m2. The subject of the experiment is the hybrids PT225, PT234, PR44W29, and PT271. Harvesting of rapeseed for green mass is done in the flowering phase. It was found that the best ratio of individual parts of plants combined with the highest content of crude protein and the lowest crude fiber was reported in the hybrid PT225. During the three years of the experiment and on average for the study period, the highest yield of green mass was obtained from the hybrid PT234 (69 250 kg/ha).
