Abstract: This study aimed at assessing the effect of planting date on the growth and yield of chickpea. Two field experiments were undertaken using a split plot design with planting dates (1, 14 and 28 May 2014; early, medium and late, respectively) as main plots and chickpea cultivar (Range 1, Range 3, Range 4 and Range 5) as subplots. Experiment I was well watered (weekly irrigation) while Experiment II was irrigated on three occasions: at planting, flowering and podding. Soil moisture content was determined at 7-day interval using a neutron probe, and crop biomass and grain yield determined at harvest maturity. Grain yield was greater with early than medium and late planting probably due to longer duration of vegetative growth and seed filling period with early planting. Soil moisture content at 30-90 cm depth varied with planting date. Clearly, planting date affects chickpea productivity in the study site.
