Abstract:

Present research was conducted to assess the performance of four cowpea genotypes (Fodder cowpea-1, konkan sadabahar, ACP-109, PCP-9702-1) under moisture stress conditions, at research farm Department of Agricultural Botany, COA, Dapoli, DBSKKV, Dapoli (M.S.). At harvest, the highest relative water content was found in genotype Konkan sadabahar (83.54), which was significantly superior over all the genotypes. The lowest relative water content was found in genotype PCP-9702-1 (76.20). Relative water content of leaf (RWC) indicates the actual water content to its maximum turgidity. From 45 DAS onwards, the difference in relative water content in all varieties due to water stress treatments became more and more prominent. Relative water content of leaf (RWC) indicates the actual water content to its maximum turgidity. It was observed that, plants under zero stressed condition had maintained higher RWC throughout the course than strong stressed and severe stressed plants. At 90 DAS, genotypes fodder cowpea-1 and ACP-109 showed less reduction in RWC under strong (4.23 %), (5.09 %) and severe (13.72 %), (14.81 %) stressed conditions than all other genotypes studied. These genotypes showed better maintenance of higher RWC ensuring better hydration and more favourable internal water relations of tissue with a possibly higher pressure potential and showed better drought tolerance capacity.
