Standardization of seed protectants for improving the seed quality of pigeonpea (Cajanus cajan L.) seed under the ambient storage

Abstract

Seven seed protectants viz., Emamectin benzoate (Proclaim 5SG) @2ppm (40.0 mg kg-1 seed), Deltamethrin 2.8 EC @1ppm (0.04 ml kg-1 seed), Tantani (Lantana camara) leaf powder @10mg kg-1 seed, Nirgundi (Vitex negundo) leaf powder @10g kg-1 seed, Citronella oil @5ml kg-1 seed), Sweet flag (Acrous Calamus) 10ml kg-1 seed, Neem (Azadiractica indica) 10g kg-1 seed were assessed for their effectiveness in which the minimum per cent damage and weight loss were observed when the seed treated with Emamectin benzoate [email protected] mg kg-1 followed by Deltamethrin 2.8 EC @0.04 ml kg-1 upto 9 months of storage under ambient condition. Germination percent was found significantly above the IMSCS level up to 9 months of storage when seed was treated with Emamectin benzoate [email protected] g kg-1 seed followed by Deltamethrin @0.04ml kg-1 seed. Percent seed moisture was depending on nature of seed protectants and storage environment. Seed vigour index was found significantly higher up to 9 months of storage when seed was treated with Emamectin benzoate [email protected] mg kg-1 followed by Deltamethrin @0.04ml kg-1 seed.
