A laboratory experiment was conducted to study the “Effect of Pre-Sowing Seed Enhancement Techniques in rice ADT 43 (Oryza sativa L.)” at Dept. of Agronomy, Annamalai University during 2021. The present investigation was carried out in completely randomized block design which consists of 16 treatments with 3 replications. The treatments contains soaking the seeds in various pre sowing seed priming chemicals viz., water,1% KCl, 3% ZnSO4, 40ppm GA3 and 1% Pungam leaf extract, were tested with different soaking duration (24, 30 and 36hr) and control. The results of the findings revealed that, the treatment T5-1% KCl (24hr) recorded higher germination percentage (95.23 %), speed of germination (29.03), seedling length (29.46 cm), dry matter production (0.43 g seedling-10), vigour index I (3029) and vigour index II (40). Lower seed quality and seedling characters were recorded in control (T1)treatment.
