Abstract

This research was carried out to investigate the effect of using seed treatment by Carboxin Thiram, Imidacloprid, polymer, GA3 and Trichoderma (Wild and Mutant with 250gy gamma rays) on Germination Rate, Final Germination Percentage, Seedling length and Vigor index performed at the Seed Technology Laboratory of Sugar Beet Seed Institute(SBSI). GA3 alone or with chemical treatments and Trichoderma in seed coating increased the germination. Seeds coated with 2g Carboxin Thiram, 2g Imidacloprid , 2g polymerand 1000ppm GA3 showed the highest percentage of germination (99%).The result showed that the use of polymer increased the germination percentage, vigor index and seedling length. Furthermore, application of seed treatment did not show any adverse effects on germination traits. On the other hand, the use of wild species of Trichoderma reduced germination traits. Reduced effect of seed coating by Trichoderma moderated with mutant species, but there was a germination reduction when compared to the control treatment.
