A laboratory experiment was conducted to study the influence of seed hardening techniques on germination and seedling characters of green gram at Department of Agronomy, Faculty of Agriculture, Annamalai University during 2021. The present investigation was carried out in completely randomized design which consists of 8 treatments and replicated thrice. Seeds of green gram variety CO-3 were treated with various pre sowing seed priming chemicals viz., 2% KCl, 2% CaCl2, 2% KNO3, 100 ppm ZnSO4, 100 ppm MnSO4 and 5 % nochi (Vitex sp.) leaf extract, distilled water and control. The study revealed that seed hardening with 2% CaCl2 improved the germination percentage (98 %), root length (14.80 cm). shoot length (16.31 cm), seedling length (31.11 cm), seedling fresh weight (5.743g), seedling dry weight (0.320g), vigour index I (3071) and vigour index II (31). Lower germination percentage, seedling character recorded in control (T1) treatment.
