Abstract Most producing countries chickpea (Cicer arietinum L.), including Iran, are located in arid and semi-arid environments. Terminal drought stress during pod formation and grain filling is the most important factor limiting the plant yield. In order to examine the effect of time of terminal drought in chickpea, a factorial experiment based on randomized complete blocks design with four replications was conducted under greenhouse conditions at the Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran. Treatments consisted of two planting dates (5 Jan and 16 Feb 2004) and the time of beginning of terminal drought in flowering and 10 and 20 days after flowering and a well-watered treatment (control). Occurrence of terminal drought at flowering and 10 and 20 days later reduced water use by 36, 24 and 15%, respectively, and dry matter production by 31, 23 and 10%, respectively. In the first sowing date, terminal drought at flowering and 10 and 20 days later resulted in 79, 71 and 7% reduction in grain yield, respectively. In the second sowing date, the reductions were 57, 57 and 42%, respectively. In general, optimal sowing date and supplementary irrigation at reproductive stages could be a great management option to decrease the negative aspects of terminal drought stress.
