Influence of Decapitations and PGR'S on Plant Growth, Seed Yield and Quality of Seed of Cluster Bean (Cyamopsis tetragonoloba L, Taub.) Variety Pusa Navbahar in Summer

摘要

A field experiment was conducted to find out the influence of decapitation and plant growth regulators on seed yield and quality of cluster bean seed cv Pusa Navbahar with three decapitation treatments and three plant growth regulators each at two concentrations with water sprays control in factorial randomized design with three replications during summer season 2013. The results observed that decapitation at 75 DAS significantly recorded maximum seed yield parameters with better quality. Plant growth regulators treatments also recorded significant result. Application of thiourea 500 mg/l at flowering stage recorded maximum yield parameters as well as seed yield (973.78 kg/ha), which was at par with GA_3 400 ppm. Combinations of decapitation at 75 DAS and spraying of thiourea 500 mg/l registered significantly higher values for all seed quality parameters except germination percentage.
