Abstract

                                The response of Dolichos bean genotypes to different seasons in relation to physiological parameters and yield was studied during 2009-2010. Leaf area, light interception, specific leaf weight, chlorophyll content, chlorophyll stability index and relative water content differed with genotypes and seasons. With respect to genotypes, Dbp-3 recorded the highest leaf area, total dry matter production, light interception, specific leaf weight, chlorophyll content, chlorophyll stability index and relative water content which in turn reflected on yield. The early sown crop i.e. crop sown at July-August season resulted in good development of physiological characters as well as yield. Among the treatment combinations, the highest value of physiological parameters and yield was recorded in Dbp-3 sown during July-August season.
