Abstract

The experiment was conducted during summer seasons of 2007 to 2009 with three sowing dates (20 March, 5 April and 20 April) and four termination of last irrigation (45, 50, 55 and 60 days after sowing) to study the growth and yield of mungbean as influenced by thermal and moisture regimes at Ludhiana. The highest grain yield (1474 kg ha-1) was recorded in April 5 sowing date. The delayed
sowing caused early maturity but increased water use. The maximum heat accumulation as well as heat use efficiency was reduced after April 5 sowing. Among the irrigation treatments, the delay in termination of last irrigation had increased crop duration, yield as well as water and heat use efficiencies.
