A pot experiment was set to find the effect of compost prepared from water-hyacinth on the experimental soil properties and on rice (BR-11) yield. Two months were needed to stable C/N ratio to 8 of water-hyacinth by decomposing in gunny bags. The compost has a positive effect on the formation of microaggregate of the soil. Water holding capacity also increased significantly with increasing content of water-hyacinth in the soil. Tremendous changes in cation exchange capacity were found with increasing application of water- hyacinth compost and it found 23.75% higher than the control at highest content of water hyacinth compost treatment. On the other hand, non-significant changes in pH occur with the application of the compost. Grain yield of rice also increases with the application of water- hyacinth compost in the soil and the highest 8.13% yield increase was obtained.
