Abstract: The seed quality of chickpea is deteriorated during ambient storage by various factors viz.; abiotic (Temperature, moisture and humidity) and biotic (insects and fungi etc.). Use of seed protectants is rapid and effective method for destroying life of insects during seed storage as well as reducingseed damage. In view of above facts in present investigation bio-efficacy (Seed moisture content, seed germination and vigour index) of botanicals were tested in seed entomology laboratory under ambient storage condition. In present investigation germination percent was found significantly above the IMSCS (Indian Minimum Seed certification Standard) level up to 6 months of storage when seed was treated with Deltamethrin 2.8 EC @ 0.04 ml kg ^-1 seed followed by Nimbecidine @ 5 ml kg^-1 seed and Karanj oil @ 5 ml kg^-1 whereas percent seed moisture was depends on nature of seed protectants. Seed vigour index was found significantly higher up to 6 months of storage when seed was treated with Deltamethrin 2.8 EC @ 0.04 ml kg ^-1 followed by Nimbecidine @ 5 ml kg-1 and Karanj oil @ 5 ml kg^-1. The present investigation advocated that botanicals,;Nimbecidine @ 5 ml kg^-1 and Karanj oil @ 5 ml kg^-1 may be utilized as suitable and safe seed protectants to maintain the seed quality above IMSCS level for a long period of 6 months.
