A field experiment was conducted to assess the response of salicylic acid (SA) and brassinolide (BS) on quality and yield of groundnut kernels. Foliar spray of salicylic acid @ 300 and 500 ppm and brassinolide@10 and15 ppm was done at vegetative (20 days after sowing) and reproductive (40 days after sowing) stages of groundnut cultivar GG-7 in kharif season. Kernel quality improved with both the growth regulators (GR) as significant enhancement of total proteins, free amino acid, reducing sugar, non-reducing sugar, total carbohydrate, total soluble sugar, total phenol, free fatty acid and pod yield was observed. Treatment of brassinolide was more effective as compared to salicylic acid with respect to pod yield and quality attributes except free amino acid content. Maximum increase in free amino acid content was found with salicylic acid @300ppm. Brassinolide@10ppm was more effective with respect to total protein content and pod yield whereas the BS@15ppm was effective with respect to remaining quality attributes. Spray at reproductive stage elicited better response in terms of yield, total soluble sugars, free amino acids and free fatty acid content.
