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 (.). At harvest, the highest relative water content was found in genotype Konkan sadabahar (), which was significantly superior over all the genotypes. The lowest relative water content was found in genotype PCP-9702-1 (). 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. | Effect of moisture stress on leaf relative water content (RWC) of four cowpea (Vigna unguiculata L. walp.) genotypes at different stages of growth
