Influence of decapitation and PGR's on yield of cluster bean seed

All physiological parameters observed higher values in combination of without decapitation and spraying of GA3 and thiourea at flower initiation. Yield and yield attributing parameters viz. number of seeds per pod and weight of 1000 seeds were the highest when cluster bean decapitate at 85 days after sowing and spraying of thiourea @ 500 mg/l. Whereas, Seed quality parameters like, seedling length, seedling dry weight and vigour index-I and II recorded the maximum values in combinations of decapitation at 70 days after sowing with treatments of GA3 and Thiourea spray. Maximum net return was obtained from decapitation at 70 days after sowing and spraying of thiourea 500 mg/l at flower initiation in cluster bean.
