Chickpea, date of sowing, irrigation, water useAbstract
A field experiment was conducted during the post-monsoon season for two consecutive years 2005-06 and 2006-07 to study the effect of date of sowing and irrigation regime on yield and water use in chickpea (Cicer arietinum L.). The results revealed that 1st date of sowing (20 November) recorded the maximum seed yield (1474.24 and 1442.58 kg ha-1 during 1st and 2nd year, respectively) as well as plant height and dry matter accumulation. The daily moisture use rate of chickpea during early vegetative stage was slightly higher with earlier sowing as compared to that of late sowing in both the experimental years. But during reproductive stage i. e. after flowering, late sown crop recorded higher moisture use. But the overall consumptive use was higher under late sown condition. Application of two irrigations at branching and pod formation resulted in higher seed yield, whereas the consumptive use was higher when the irrigation was applied at branching and flower initiation. Total moisture use was lowest under rainfed condition that led to lower seed as well as biomass yield. However, the chance of rainfall (Kal Baisakhi) during March in the new alluvial zone of West Bengal must be taken into consideration while scheduling irrigation during pod formation.
