Seed priming is a valuable agronomic practice for improving seed performance, establishment, and crop productivity. This research investigated the influence of different seed priming treatments on the growth, yield, and seed quality of groundnut variety VRI 2 through field and laboratory evaluations. The treatments included hydropriming, 1% CaCl2 , 1% ginger rhizome extract, 1% garlic bulb extract, and 1% Panchagavya, with an untreated control. Among the treatments, 1% Panchagavya (T6) demonstrated superior performance, achieving the highest field emergence (89%), plant height (61.92 cm), number of pods per plant (44.84), and seed yield per hectare (36.55 q/ha). Laboratory assessments also indicated that T6 recorded the best results in germination percentage (84%), root length (8.91 cm), shoot length (13.24 cm), and seedling vigour indices. Hydropriming (T1) showed moderate effectiveness, whereas the untreated control consistently yielded the lowest values across all parameters.
