Abstract

Sorghum (Sorghum bocolor L. Moench) is a species of cereals that can be used for food, animal feed and raw materials for industry such as liquid sugar, beer and bioethanol. Sorgum has wide adaptability so that it is an appropriate comodity to be developed in coastal lands. Using soil amendments will improve the quality of soil from coastal areas using for growing sorghum. The research was done in the village of Sungai Hitam, District of Muara Bangkahulu, Bengkulu, Indonesia, from June to October, 2016. The objectives were to study early growth response of sorghum grown in polybag using coastal soil as growing media with the addition of soil amendments including compost of oil palm empty fruit bunches (EFB) and Wedelia. The doses of each compost were 0.0, 2.5, 5.0, 7.5, 10.0, 12.5, and 15.0 ton ha -1. The experiment was arranged in completely randomized design with four replications. The results showed a linear response of the early growth of sorghum to the doses of EFB and Wedelia composts in term of plant height and stem diameter at 2, 4, 6, and 8 weeks after planting (WAP). Similar responses were observed on the leaf areas, dry weight of above ground biomass and root biomass of sorgum at 8 WAP. Overall, green organic compost affected the early growth of sorghum significantly, and the highest effect was observed at the highest dose of compost which was 15.0 ton ha-1. The effect of Wedelia compost on early growth of sorghum was better than EFB compost. Key words: coastal soil, compost, EFB, sorghum, Wedelia.
