Abstract

                                Determination of physiological maturity is essential to harvest the seeds with high quality. The study on these aspects in cluster bean (Cyamopsis tetragonoloba) cv. Pusa Navbhagar revealed that, based on physical (fresh and dry weight of pod and seed, length and width of pod and seed), physiological (germination, root length, shoot length, drymatter production and vigour index), biochemical (protein) and visual (pod and seed coat colour) indices, the cluster bean seeds reached their physiological maturity at 50 DAA where the moisture content of seed was 18.2 per cent

Key words : Cluster bean, physiological maturity, seed vigour
