Abstract:
This study was designed in order to evaluate the growth and yield performance of some winged bean genotypes (Psophocarpus tetragonolobus) i.e. EC178335, IC026946, PWB 17-1, AKWB-1, Indira Winged bean -1, RMDWB-1 and PWB-11-2 and their responses to different levels of NPK fertilization. The seven mentioned genotypes were fertilized with four NPK levels i.e. control (no fertilizer), 75% RDF, RDF(20:40:20) and 125% RDF. Data showed that Amongst the growth parameters, significantly higher days to 50% flowering and days to pod setting was recorded with PWB17-1 and AKWB-1 respectively while lowest in EC178335 in both growth parameters however significantly higher days to 50% flowering was recorded with application of 125% RDF and lowest in control while days to pod setting and pod length was not significantly influenced due to fertilizer levels, significantly higher pod length was recorded with RMDWB-1. Amongst the yield attributes, number of pods per plant, number seeds per pod was significantly higher with genotype AKWB-1 while significantly higher 100 seed weight was recorded with genotype IC026946 however fertilizer levels was not significantly influenced the any yield attribute, significantly higher grain yield, gross returns, net returns and B:C ratio were found in genotype AKWB-1 and least was observed in the genotype Indira winged bean-1 and in fertilizer RDF(20:40:20) and 75% RDF as compared to control.
