A field experiment was conducted during kharif season of 2013 to find out the effect of mulching and NPK levels on pearl millet (Pennisetum glaucum) in bael (Aegle marmelos) based agri-horti system under rainfed condition of Vindhyan region. There were twelve treatment combinations comprised of three levels of mulching (no mulch, wheat straw mulch and dust mulch) and four levels of RDF NPK (50%, 75%, 100%, 125%). The experiment was laid out under split-plot design with three replications. Significant improvement was recorded in growth and yield attributes viz., plant height, number of leaves per plant, number of tillers per plant, dry matter accumulation per plant, number of ears per plant, ear length, number of grains per ear, 1000-grain weight, grain yield, stover yield, harvest index (%), nutrient uptake and economic returns. Significantly higher yield of pearl millet (1908 kg/ha) was observed in the plot that received 125% RDF, which was found at par with the 100% RDF and in case of mulching, the maximum yield was observed with dust mulch (1942 kg/ha) than all other treatments. The application of dust mulch and 125% of the recommended dose of fertilizer (RDF) NPK (T12) treatment have distinct superiority as compared to all other treatments under bael based agri-horti system and more suitable for moisture conservation practice in pearl millet.
