OAR@ICRISATEvaluation of groundnut response to early moisture stress during the rainy and the post-rainy seasonsP SSarmaauthorM V KSivakumarauthorThe response of groundnut (Arachis hypogaea L.) to early moisture stress (EMS), imposed from emergence to initiation of pegs, was evaluated during the 1982 rainy season at the ICRISAT Research Center, Patancheru, India on a medium deep Alfisol, and was compared with the treatment responses during the 1982–1983 post-rainy season. EMS was imposed during the rainy season by covering the plots with black plastic film to keep off the rain while during the post-rainy season a line source sprinkler irrigation system was used. EMS reduced evapotranspiration with no apparent reduction in LAI, and pod and kernel growth during the rainy as well as the post-rainy seasons. Hence water-use efficiency was substantially higher for the EMS treatment as compared with the control during the two seasons. Despite the contrasting climatic conditions during the rainy and post-rainy seasons, groundnut response to EMS was fairly similar. The implications of these results for developing improved water management strategies for groundnut are discussedGroundnut1990ElsevierArticle
