Abstract:
Winged bean (Psophocarpus tetragonolobus (L.) DC.) is a versatile and underutilized leguminous crop primarily found in tropical regions. It boasts high protein and mineral content. This study focused on examining the “"Growth and Yields of Winged Bean (Psophocarpus tetragonolobus L.) Genotypes in the New Alluvial Zone of West Bengal”. The present investigation was conducted at the Horticultural Research Station, Mondouri, Nadia under Department of Vegetable Science, Faculty of Horticulture at Bidhan Chandra Krishi Viswavidyalaya. The experiment employed a Randomized Block Design with three replications and duration spanning from July 2019 to February 2020. The treatments consist of 20 genotypes (viz.- VRWB-17, VRWB-23, VRWB-13-1, VRWB-84, VRWB-21, VRWB-09, VRWB-95, VRWB-18, VRWB-4A, VRWB-13, VRWB-83, VRWB-20, VRWB-12, VRWB-60, VRWB-22, VRWB-11-2, VRWB-26, VRWB-4B, VRWB-11, VRWB-13-6). Amongst the genotypes VRWB-09, VRWB-11-2, and VRWB-17 demonstrated superiority over others. Among the 20 genotypes evaluated, VRWB-84, VRWB-09, VRWB-22, and VRWB-18 exhibited early flowering (68.66, 69.33, 69.33, and 70.33 days, respectively), while VRWB-23 and VRWB-13-1 were categorized as late flowering (83.33 and 82 days, respectively). The highest number of pods, 151.66 per plant, was observed in genotype VRWB-09. Genotype VRWB-95 exhibited the highest pod weight of 31.98 g. The Genotype VRWB-11-2 achieved the highest green pod yield per plant of 3.56 kg and the number of seeds per pod varied among the genotypes, with the highest number observed in VRWB-13 (12.17), followed by VRWB-26 (12.00) and VRWB-18 (11.50). Furthermore, genotypes with a higher number of seeds per pod and greater bearing capacity per plant generally yielded higher seed production.
