The fungicide, ceresan, at two levels, 0 and 0.4%, four growth hormones, 1-naph thyl acetic&amp;nbsp; acid&amp;nbsp; (NAA) ,&amp;nbsp; indole&amp;nbsp; acetic acid (IAA) , gibberellic acid (GA,)&amp;nbsp; and kinetin, with seven concentrations (0, 5, 10, l5, 20, 25 and 30 ppm) and four seed soaking periods (1, 3, 5 and 7 hours) were applied to mechanically extracted seeds from teak fruits before sowing. Presowing seed treatments significantly influenced germination of seeds&amp;nbsp; after&amp;nbsp; seven&amp;nbsp; days. Under fungicide application maximum&amp;nbsp; seed germination&amp;nbsp; was recorded&amp;nbsp; in NAA&amp;nbsp; at 25 ppm, with 3 hours soaking followed by GA, at 15 ppm, 5 hours&amp;nbsp; and&amp;nbsp; IAA&amp;nbsp; 5 ppm,&amp;nbsp; 5 hours. Longer soaking time (7 hours) did not favour seed germination. Relative cost/benefit ratio of hormone application and economics of seed treatment with fungicide and hormones showed that NAA and IAA, 5 ppm with fungicide were the best treatment, recovering the cost of seeds by a factor of 9.83 times over the control due to enhancement of seed germination. This seed treatment is found suitable for raising teak seedlings in root trainer in modern forest nursery.&lt;/p&gt;}, number={1}, journal={Journal of Tropical Forest Science (JTFS) }, author={R. K.
