Abstract:
Two field experiments were carried out at Adhiparasakthi Agriculture College, Kalavai during winter and summer season to study the effect of seasonal variations on growth parameters, physiology attributes and yield parameters of different cluster bean cultivars. The genotypes viz., Ankur Rani, super11, Krishna 41, Mansi, Kallakurchi, Thiyagadurgam, Cheyyar, Cuddalore, Lakshmi, Needamangalam, Poigai and Pusa Navbahar were taken up for the study. The result reveled that among the two seasons, summer sowing recorded the higher plant height (95.98 cm), root length (12.43), number of branches per plant (11.59 nos), leaf area index (1.37), total dry mater (26.11g/plant), net assimilate rate (0.254), crop growth rate (0.040) in the genotype Pusa Navbahar followed by Ankur Rani. The green pod yield is (756 q/ha.) and benefit cost ratio (3.83) was also recorded high in genotype Pusa Navbahar.
