Abstract: A field experiment to study the nutrient management practices through organics in sesame was conducted at the ARS, Hanumanamatti (Ranebennur), University of Agricultural Sciences, Dharwad on Alfisols during kharif 2007. The experiment comprised of five main plot treatments mainly, Beejamrut + Jeevamrut + mulching, with organic pest management (NM1), FYM (1/3) + Vermicompost (1/3) + Green manuring (1/3) equivalent to RDN +organic pest management (NM2), FYM (1/3) +Vermicompost (1/3) + Green manuring (1/3) equivalent to RDN + FYM + organic pest management (NM3), RDF + FYM + Azospirillum + Trichoderma with IPM (NM4), RDF alone with chemical plant protection (NM5), and three sub plot treatments mainly, one spray of panchagavya at 30 DAS (PS2), two sprays of panchagavya at 30 DAS and flowering stage (PS3), and a control. The treatments were replicated thrice and experiment laid out in a split plot design. Integrated nutrient management (NM4) recorded significantly higher sesame yield (296.52 kg/ha) over rest of the manurial treatments. Among liquid manures, treatment PS3 recorded significantly higher sesame yield (239 kg/ha) over control (231.61 kg/ha). The values for growth and other yield parameters were also significantly higher in these treatments. Among manurial treatments, NM3 recorded significantly higher microbial population and available N, P2O5 and K2O content in the soil. Among liquid manures, PS3 recorded higher microbial population and available N, P2O5 and K2O content in the soil. Economic analysis clearly indicated that net returns in sesame were significantly higher (Rs.4860/ha) with NM5 over rest of the treatments, whereas B: C ratio was significantly higher with NM1 over rest of the treatments. As this is the first year trial, organics alone could not achieve the higher yield of sesame although it has beneficial effects on soil fertility and microbial activity. Hence, the integrated nutrient supply system provided an ideal nutrition for crop and produced higher yield in sesame.
