The present study was conducted during kharif, 2012 and 2013 at ICAR-Indian Agricultural Research Institute, New Delhi to find out the effect of moisture management and zinc fertilization on performance of pearlmillet under rainfed conditions. Results of two year study showed considerable improvement in growth and productivity of pearlmillet. Flat bed with 5.0 t/ha crop residue recorded significantly higher plant height, dry matter accumulation, number of earheads, grain weight per earhead, yield and profitability as compared to flat bed without crop residue and flat bed with 2.5 t/ha crop residue. In terms of total number of tillers, length of earhead, 1,000 grain weight and returns per rupee invested flat bed with 2.5 and 5.0 t/ha crop residue and narrow bed and furrow with 2.5 t/ha crop residue remained statistically similar with each other. However, significantly higher values of root parameters viz., root length, root volume and root dry weight were observed with flat bed without crop residue. Under zinc fertilization treatments application of 5.0 and 2.5 kg Zn/ha being at par with each other and proved significantly better over control in terms of growth parameters except dry matter, yield attributes, stover yield, harvest index and returns per rupee invested of pearlmillet. Whereas, fertilization of pearlmillet with 5.0 kg Zn/ha resulted significantly higher dry matter accumulation, grain and biological yield and profitability over lower levels of zinc. Residual effect of zinc fertilization was also found to be significant in pearlmillet. Most of the parameters of pearlmillet showed significant response only up to 2.5 kg Zn/ha. Final results revealed that pearlmillet shown under flat bed with 5.0 t/ha crop residue or narrow bed and furrow with 2.5 t/ha crop residue and application of 2.5 kg Zn/ha to pearlmillet or chickpea were proved to be better.
