Choudhary and J. M. SutaliyaAbstract This study was conducted to investigate the response of pearl millet genotypes to rainfed and irrigated conditions. The experiment was laid out in a factorial randomized block design under rainfed and irrigated conditions with four pearl millet genotypes i.e. HHB 67 (Improved), HHB 197, HHB 223 and HHB 234. The maximum plant height (216.3 cm), root weight (19.13 g plant-1), yield attributing characters and yield (31.19 q ha-1) were higher under irrigated condition by maintaining higher leaf water potential, relative water content (RWC) and canopy temperature depression. Root length was higher (97.9 cm) in rainfed condition. Early panicle initiation, 50% flowering and physiological maturity were recorded in rainfed condition than irrigated condition. Genotype HHB 234 recorded higher plant height while higher ear head girth (2.6 cm) and test weight (11.16 g) were observed by HHB 223 genotype. Genotype HHB 67 (Improved) showed early panicle initiation, 50 % flowering and physiological maturity than other genotypes. Interaction effect was found significant and genotype HHB 223 recorded higher plant height, root length, root dry weight, leaf water potential, relative water content, canopy temperature depression, yield attributes and yield under irrigated condition but under rainfed condition these were higher in HHB 234.
