Abstract

A field experiment was conducted during khanfseasons of 2005 and 2006 to study the effect of bio-organics and inorganic sources of nutrient supply on quality seed production of groundnut in midhill altitude of Meghalaya. Treatments comprised off our biofertilizers andseven organo-inorganic sources of nutrient supply were tested in split-plot design with three replications. Maximum seed yield and seed quality were recorded with combined inoculation of Rhizobium + PSM followed by individual inoculation of Rhizobium and PSM. Application of lime @ 500 kg/ha + FYM @ 10 tonnes/ha + 50% NPK recorded highest seed yield and seed quality attributes. Seed inoculation with Rhizobium + PSM in the presence of lime + FYM and 50% NPK improved seed yield and nutrient uptake of groundnut. Highest net return and benefit cost ratio was observed with combined application of Rhizobium + PSM and lime + FYM + 50% NPK
