Abstract: A field experiment was conducted at the experimental field twelve blackgram genotypes under moisture stress condition. A wide diversity among the genotypes in their growth parameters was recorded. Genotypes varied from genotypes TBG-104, KU-12-13 and KU-12-37 showed higher values of Crop growth rate, Net assimilation rate, leaf area index and leaf area duration during moisture stress condition than irrigated condition. TBG-104 and KU-12-13 recorded significantly higher values in both irrigated as well as stress conditions, which denotes the ability of these genotypes was sustained under severe moisture stress at pod filling stage of crop. Whereas LBG-752 and LBG 20 recorded lower values of CGR and NAR as well as NDU 12-300 and KU 12-14 showed lowest values of LAI and LAD during both rabi 2015-16 and rabi 2016-17.
