A field experiment entitled, "Effect of inorganic and bio-fertilizers on growth and yield of summer groundnut (Arachis hypogaea L.)" was conducted at PG Research Farm, Agronomy Section, R.C.S.M. College of Agriculture, Kolhapur during summer, 2019. The experiment was laid out in factorial randomized block design (FRBD) with three replications and nine treatment combinations of three inorganic fertilizer levels viz., F1-75% RDF (18.75:37.5:0 kg ha -1 ), F2-100% RDF (25:50:0 kg ha -1 ), F3-125% RDF (31.25:62.5:0 kg ha -1 ) and three bio-fertilizers levels viz., B1-Control, B2-Rhizobium spp.+ PSB (Lignite based), B3-Rhizobium spp.+ PSB (Liquid based). The application of 100% of RDF ha -1 was found at par with 125% of RDF ha -1 and significantly superior over 75% RDF ha -1 in respect of recording higher value of the growth character and yield viz., plant height (cm), number of branches plant -1 , plant spread plant -1 (cm), dry matter plant -1 (g), number of nodule plant -1 ,weight of nodule plant -1 (g), dry pod yield (q ha -1 ), haulm yield (q ha -1 ), biological yield (q ha -1 ), and harvest index (%). The dual seed inoculation of Rhizobium spp. + PSB (Lignite based) significantly superior over control and at par with Rhizobium spp. + PSB (Liquid based) in respect of recording higher value of growth attributes and yield viz., mean plant height (cm), plant spread (cm), number of branches, dry matter plant -1 (g), number of nodule plant -1 , weight of nodule plant -1 (g), dry pod yield (q ha -1 ), haulm yield (q ha -1 ), biological yield (q ha -1 ) and harvest index (%).

A field experiment entitled, "Effect of inorganic and bio-fertilizers quality of summer groundnut (Arachis hypogaea L.)" was conducted at PG Research Farm, Agronomy Section, R.C.S.M. College of Agriculture, Kolhapur during summer, 2019. The experiment was laid out in factorial randomized block design (FRBD) with three replications and nine treatment combinations of three inorganic fertilizer levels F1-75% RDF (18.75:37.5:0 kg ha -1 ), F2-100% RDF (25:50:0 kg ha -1 ), F3-125% RDF (31.25:62.5:0 kg ha -1 ) and three bio-fertilizers levels B1-Control, B2-Rhizobium spp. + PSB (Lignite based), B3-Rhizobium spp.+ PSB (Liquid based). The crop was fertilized as per treatments by using urea and single super phosphate was given by placement method. The application of 100% of RDF ha -1 was comparable with 125% RDF ha -1 significantly over 75% RDF ha -1 in respect of recording higher value of quality attributes viz., oil content in kernel, oil yield, protein content in kernel and protein yield. The dual seed inoculation of Rhizobium spp. + PSB (Lignite based)as well as Rhizobium spp. + PSB (Liquid based) in respect of recording higher value of quality attributes viz., oil yield, oil content in kernel, protein content in kernel and protein yield. The quality attributes of groundnut were not influenced by the interaction effect of both the factors. This indicates that the both factors under study viz., inorganic and biofertilizer levels behaved independently in respect of quality of summer groundnut variety.
