Effect of cutting management on seed yield and quality attributes of tetraploid berseem

Berseem is an important rabi fodder crop in India but its seed productivity is quite low compared to other countries. Tetraploid varieties have a margin in seed size and fodder quantity than diploid varieties however, their yield potential is low. The present study was conducted in the newly developed bold seeded tetraploid berseem variety, Bundel Berseem-3 (BB-3), to improve the seed yield through cutting management by taking differential date of last cut. Influence of last cut on various phenophases, yield parameters, seed yield and quality was studied. Significant differences were noted in the flowering period as well as yield attributes under various cutting regimes. Seed yield decreased with increased date of last cut. Seed quality measured in terms of germination and vigour also decreased with delay in date of last cut. February ending to March I week was found to be the more suitable period for last cut in Bundel Berseem-3 variety in areas where the temperature range is between 5-27 degrees C (Min.) and 22-41 degrees C (Max.) during February to May.
