Abstract: A field experiment was carried out during 2015 at IARI, New Delhi to study the effect of planting density and nitrogen management practices on growth, micronutrient content and soil fertility under conservation agriculture based pearlmillet (Pennisetum glaucum L. R. Br. emend Stuntz). The experiment comprised of three main-plot treatments viz. normal distance sowing, high density sowing fb alternate row harvesting for fodder at 35 DAS and high density sowing fb alternate row harvesting for fodder at 45 DAS and five sub-plot treatments viz. control, 60 kg N/ha as basal, 30 kg N/ha as basal + 30 kg N/ha as side dressing, 75 kg N/ha as basal, and 37.5 kg N/ha as basal + 37.5 kg N/ha as side dressing. High density planting resulted in significant improvement in growth parameters (plant height, dry matter accumulation and leaf area index) at initial stage. But at later stages, these parameters along with no. of tillers were significantly higher in normal distance sowing. Higher growth was obtained with basal application of 75 and 60 kg N/ha over split application and control. Whereas, all the above growth parameters and total no. of tillers during later stages (60 DAS and at harvest), were improved significantly by 37.5 kg N/ha as basal + 37.5 kg N/ha as side dressing and remained equivalent to basal application of 75 kg N/ha. Similarly, micronutrient uptake was also higher under normal distance sowing. In pearlmillet, micronutrients content and total uptake, available N, P and K and soil microbial biomass carbon and enzymatic activities were increased significantly with the application of 75 kg N/ha either as basal or in splits.
