Rabi‐summer‐produced (dry season, February–May) groundnut ( Arachis hypogaea L.) cv. GG 2 was dried using three different methods, viz. windrow (W), windrow‐shade (WS) and DOR (Directorate of Oilseeds Research) methods and stored in polyethylene lined gunny bags with or without desiccant (CaCl 2 or silica gel, 10gkg −1 pods). The seeds were analysed for the retentation of seed viability, seedling vigour, membrane integrity and Held emergence during storage, and crop stand and pod yield after 12 months of storage. The drying and storage method significantly affected the getminability, seedling vigour and field emergence. Both root length and seedling biomass were adversely affected due to windrow drying (W) The quick loss of viability in the W treatment was associated with an increase in electrical conductivity of the seed leachate. The retention of higher seed viabiliry and vigour in the seeds dried by DOR method and stored with CaCl 2 (DOR C) was due to lower drying remperarures and lower pod moisture during the initial storage period. The DOR C method was found to be an effective drying and storage method for retaining acceptable seed viability and vigour till the following rabi‐summer sowing of groundnut.
