The response of chickpea to 4 available soil moisture depletion levels (ASMDL1-50%, ASMDL2-65%, ASMDL3-80% and ASMDL4-95%) and 4 topping treatments (T1-nipping at 5 cm from ground level, T2-nipping at 10 cm from ground level, T3-removal of 2 cm growing tips, T4-control) were studied in Pakistan, during the 2004/05 and 2005/06 cropping seasons. Crop growth rate and total dry biomass was significantly affected by ASMDL and topping treatments. Maximum plant height was recorded in ASMDL1 (68.93 cm) and decreased by 25% by severe cutting (T1). Number of pod-bearing branches per plant was maximum (19.61) in ASMDL3 × T3, which was declared by 50% in ASMDL1 × T1. T1 delayed maturity and reduced 34% flower duration. Water deficit (ASMDL4) decreased by 23% the total dry biomass and maximum water use efficiency (48.18 kg/ha/mm) for total dry matter was recorded in ASMDL3. Biological yield was decreased by 22% severe topping (T1). Maximum crop growth rate (14.10 g/m2/day) was recorded in ASMDL3 × T3 during 2005-06. It was concluded that 80% available soil moisture depletion level (ASMDL3) with mild topping (T3) proved to be the best for higher CGR (11.77 g/m2/day) and total dry matter (7644.22 kg/ha) in chickpea.
