Abstract: Pre-sowing treatment of peanut seeds with antioxidant hydroquinone with 20 mM water solution for 12 h significantly decreased the incidence of seed-borne fungi viz., Aspergillus flavus, A. niger, Penicillium spp., Fusarium solani, F. oxysporum, Rhizoctonia solani, Sclerotium bataticola, Trichothicium sp. and Cladosporium sp. Cephalosporium sp. and Bipolaris sp., were completely inhibited. Hydroquinone also enhanced the growth parameters viz., plant height, root length, shoot length, plant weight, root weight, shoot weight, number of branches, pegs, pods and dry weight of plant producing a 50% increase in yield from 1080 to 1555 kg/acre.
