A field experiment was conducted during rabi seasons of 2012-13 and 2013-14 to study the effect of moisture conservation and zinc fertilization on quality, nutrient uptake, profitability and moisture use indices of chickpea in pearlmillet-chickpea cropping sequence under limited moisture conditions. Moisture conservation and zinc fertilization brought considerable improvement in quality, nutrient uptake, profitability and moisture use indices of chickpea during both the years of study. Chickpea planted under flat bed with 5.0 t/ha crop residue recorded significantly higher protein yield and total uptake of N, P and K during both the years of study as compared to flat bed without crop residue and flat bed with 2.5 t/ha crop residue. However, in terms of protein content during 2012-13 and soil profile temperature during both the years all the treatments received crop residue remained at par with each other and proved significantly superior over flat bed without crop residue. Planting of chickpea under narrow bed and furrow fetched significantly higher net returns ( 55,871 and 55,263/ha) and production efficiency ( 372.5 and 337.0/ha/day) and moisture use efficiency (12.34 and 11.05 kg/ha-mm) during both the years of study over flat bed without crop residue and flat bed with 2.5 t/ha crop residue. Whereas, this treatment recorded significantly higher B:C ratio over flat bed with 5.0 t/ha crop residue. Under zinc fertilization, direct application of 5.0 kg Zn/ha significantly improved the protein content in grain during 2013-14 and protein yield, total uptake of N and P, net returns and production efficiency during both the years of investigation over lower levels. But application of 5.0 and 2.5 kg Zn/ha being at par with each other proved significantly better over control in terms of protein content during 2012-13 and total uptake of P, B:C ratio and moisture use efficiency of chickpea during both the years. Residual effect of zinc fertilization was also found to be significant on chickpea. The significant improvement in quality, nutrient uptake, profitability and moisture use efficiency were observed only up to 2.5 kg Zn/ha.
