Weed control is a common practice in sorghum (Sorghum bicolor, L.) cultivation to prevent yield loss. The results showed that the most weed inhibition was observed in the treatment of rice straw mulch for 5 weeks after planting date (WAP) and at harvesting with a dry biomass weight of 13.49 g and 9.61 g, respectively. Nonetheless, the organic mulch had no prominent effect on sorghum yield. Keller variety had the highest biomass, but the yield was lower than the other two varieties. The result indicated that Keller variety was more suitable for animal feed, while Samurai and Super-2 varieties were prospective for human consumption. In addition, all tested sorghum varieties are potentially cultivated in the tropical coastal environment.
