Effect of Enriched TSP Polymer Seed Coating on Germination Physiology of Greengram Var. CO8

During 2023, the research was carried out under laboratory condition at the Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore, to find out the effect of TSP polymer seed coating on germination physiology of green gram. The seeds were coated with TSP polymer, TSP polymer with preservatives, TSP polymer with PGRs and TSP polymer with preservatives and PGRs @ 6 g/ kg of seeds. Among the various constituents of polymer, TSP polymer with preservative (0.1% Sodium sorbate) and PGR (1.5 ppm BRs) performed better with good speed of germination and seedling vigour.
