Abstract: Breaking of dormancy in seeds of Centrosema pubescens was investigated through laboratory experiment to elucidate the best method that can be used to enhance germination of the seed. The treatment were: 1) control, 2) scarification with sand paper, 3) immersion in hot water (80oC) for 2, 4, 6, 8 and 10 minutes and 4) immersion in sulfuric acid for 3, 6, 9, 12, 15, 18, 21 and 24 minutes. The results showed that regardless of immersion time, sulfuric acid scarification had the highest germination percentage, followed by scarification with sand paper and immersion in hot water. The lowest germination percentage was obtained in control. Scarifications with sulfuric acid for 18 minutes was the best method for breaking dormancy of Centrosema pubescens which resulted in an increased total germination to 100% , the highest germination speed and the lowest germination time.
