ABSTRACT:

The study of water hyacinth was carried out at 4 aquatic types (river, canal, fish pond and irrigated pond). The experiment consisted of 3 plots of 4m2in each water-body, all parameters were determined weekly and continuously for 6 weeks. The results showed that water hyacinth grows best in fish ponds and lowest in the river. The growth of water hyacinth in canals was not significantly different from irrigated ponds (p > 0.05). The dry matter (DM) of water hyacinth in fish ponds, canal and irrigated ponds dramatically higher (542 - 572g DM/m2than in the river 104,46 gDM/m2. DM of water hyacinth in fish ponds was not different from the canal (p>0.05) but significantly different from irrigated ponds and river (p<0.05). Doubling time of water hyacinth in the fish ponds, canals and ditches was relatively short at about 11 days and 23 days for rivers. The results of the study are the basis to help the local agencies in planning water hyacinth farming area for handicraft or other purposes.
