Seeds of hairy indigo, a tropical legume cover crop, are dormant due to hard seed coats. Immersion of the seed in concentrated H2SO4 for 20 or 30 minutes or hot water at 70° to 80°C for 2 minutes, significantly increased the germination percentage and rate. H2SO4 was more effective than hot water. Redrying the seed after treatment improved the effectiveness of the treatments slightly.
