摘要：A field experiment was conducted during kharif season of 2013 to find out the effect of mulching andNPK levels on pearl millet (Pennisetum glaucum) in bael (Aegle marmelos) based agri-horti systemunder rainfed condition of Vindhyan region. There were twelve treatment combinations comprised ofthree 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 ofleaves per plant, number of tillers per plant, dry matter accumulation per plant, number of ears perplant, 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) wasobserved in the plot that received 125% RDF, which was found at par with the 100% RDF and in caseof 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-hortisystem and more suitable for moisture conservation practice in pearl millet.
