An experiment was conducted at SRM College of Agricultural Sciences Vendhar Nagar, Baburayanpettai, Chengalpattu District,Tamil Nadu to study the ““Effect of presowing treatment on seed germination of Adenanthera pavonina”. The experiment was laid out in Completely Randomized Design (CRD) with three replications. The experiment involved seed scarification method. There were nine treatments, viz.,T1- Conc. Sulphuric acid (5 min.)  + 12 hours water soaking, T2 - Conc. Sulphuric acid (5 min.)  + 24 hours water soaking, T3 - Conc. Sulphuric acid (10 min.)  + 12 hours water soaking, T4 - Conc. Sulphuric acid (10 min.)  + 24 hours water soaking, T5 - Hot water + 12 hours water soaking, T6 - Hot water + 24 hours water soaking, T7 - Water soaking (12 hours), T8 - Water soaking (24 hours), T9 - Control (Without treatment).The observations were recorded for the seedling characters like Days for germination (Days), Germination percentage (%), No. of leaves, Root length (cm), Shoot length (cm), Vigour index. Soaking the seeds in water for 24 hrs was the most effective for inducing better seed germination in Adenanthera pavonina.
