A field experiment was carried out during rabi, 2010-11 to study the growth, yield, moisture extraction pattern and nutrient uptake in chickpea as influenced by irrigation and sulphur levels. Scheduling irrigation based on IW/CPE ratio and application of sulphur significantly influenced the growth, yield, moisture extraction pattern, nutrient uptake and quality of chickpea. Higher values for all these parameters along with net return and B : C ratio were obtained with scheduling irrigation at IW/CPE ratio of 0.9 which was statistically at par with 0.7 IW/CPE ratio. The study revealed that higher amount of moisture was extracted from surface layers irrespective of irrigation schedule and depletion of soil moisture by the crop increased with increasing frequency of irrigation. The highest water use efficiency was recorded under farmer’s practice of irrigation schedule, while the lowest was recorded with IW/CPE ratio of 0.9. Among the three levels of sulphur i.e. 0, 20 and 40 kg ha-1, application of 40 kg S ha-1 being at par with 20 kg S ha-1 recorded higher grain yield, net return and B : C ratio. But interaction of irrigation scheduled at 0.7 IW/CPE ratio with application of 20 kg S ha-1 recorded 32 % higher grain yield and higher B : C ratio over other treatment combinations.
