EFFECT OF ORGANIC MANURE AND BIOFERTILIZERS ON SEED QUALITY OF GROUNDNUT (ARACHIS HYPOGAEA L.)

Abstract

A field experiment was undertaken in the experimental field of Seed Technology Research Unit, Dr.PDKV, Akola (MS) during kharif season of 2010-2011 with a view to study the effect of four soil treatments viz. FYM (20t ha¹) + Rhizobium inoculation (5kg ha^-1), vermicompost (3t ha^-1) + Rhizobium inoculation (5kg ha^-1), green manuring (10t ha^-1) + Rhizobium inoculation (5kg ha^-1) and Control (RDF) combination with seed treatments viz. No seed treatments, Trichoderma viride (2g kg^-1 of seed) and PSB treatment (25g kg^-1 of seed) on seed quality of groundnut variety TAG-24. Application of vermicompost + Rhizobium in combination with Trichoderma seed treatment increase germination percentage (94.5%), seedling length (18.40cm), seedling dry weight (0.39g) and vigour index (1738.43), shelling percentage (76.40%), protein content (29%) and oil content (43.20%) in comparision to other treatments. Vermicompost (3 t/ha) + Rhizobium (5 kg/ha) in combination with Trichoderma viride (2 g/kg of seed) seed treatment was most beneficial for inhancing seed quality of groundnut because of increase in availability of nutrient, enhance nutrient uptake and activity of microbial agent.
