dc.description.abstractThe present study entitled “Effect of fertility levels on growth, yield and quality of pearl millet [Pennisetum glaucum (L.). R. Br. Emened. Stuntz] hybrids” was conducted at Research farm, CCS Haryana Agricultural University, Hisar during the kharif season, 2005 with the objective to study the effect of different fertility levels on growth, yield and quality of pearl millet hybrids and work out the nitrogen, phosphorus and potassium uptake and economics of pearl millet cultivation under varying fertility levels. The experiment was conducted with three replications in factorial randomized block design. Though different pearl millet hybrids did not differ significantly in respect of plant population, but differed significantly in growth (plant height, LAI, LAD, number of tillers phant-1 and dry matter accumulation plant-1), yield attributing characters (effective tillers plant-1, tiller conversion index, ear length, ear girth and 1000-grain weight). Grain yield ha-1 did not differ significantly among hybrids. Interaction of pearl millet hybrids x N + P2O5 levels on grain yield was observed to be non significant. In order to compute the response of individual hybrids original grain yield data on interaction of pearl millet hybrids and levels of N + P2O5 was used. Response of various pearl millet hybrids except HHB-67 Improved to varying levels of N + P2O5 application was quadratic, economic optimum dose for HHB-94 and HHB-197 was computed to be 105.48 kg N + 26.33 kg P2O5 and 89.83 kg N + 22.29 kg P2O5 ha-1, respectively. Various levels of fertility did not influence the plant population of pearl millet significantly. However, plant growth in terms of height, tillers, leaf area index, leaf area duration and dry matter accumulation plant-1 increased significantly with increasing levels of fertility at most of the stages of observation. Similarly, yield attributing characters (effective tillers, ear length, ear girth and 1000 grain weight) and grain yield increased significantly with increasing levels of fertility. N, P and K content (%) and their uptake (kg ha-1) increased with increasing levels of fertility. Net returns increased with increasing levels of fertility up to 160 kg N + 80 kg P2O5 ha-1.en_US
