Effect of inorganic and bio-fertilizers on quality of summer groundnut (Arachis hypogaea L.)

Abstract

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.
