In order to study the response of mungbean varieties to irrigation at various stages (continuous, vegetative and flowering), an experiment was conducted at Bundelkhand region, Jhansi during summer session 2010 and 2011. Continuous irrigation, irrigation at vegetative stage and irrigation at flowering stages had significant effect on yield and yield components. Irrigation at the vegetative or flowering stage reduced plant height, number of pods plant, leaf area index, no. of seeds pod, straw and seed yield. There were significant differences among genotypes. Also, irrigation × genotype interactions showed significant difference on plant height, number of pods per plant, leaf area index, number of seeds pod, and seed yield while, non-significant days to 50% flowering, days to maturity and straw yield. Among five varieties of mungbean, variety SML-668, gave significantly higher number of pods per plant, number of seeds pod and seed yield. The highest seed yield was recorded in continuous irrigation.
