Evaluation of ratio variation of water hyacinth (Eichhornia crassipes) on the production of pig dung biogas was investigated. Water hyacinth was blended and mixed with pig dung in different ratio. The blended water hyacinth and pig dung was weighed in ratio 1:1 and 1:3. These were mixed together separately in a sterile container with water to form slurry, they were then poured individually into two digesters. The temperature of the digesting materials and the environment was determined daily; also the pH was measured every two days. The temperature was between 27C 34C in the digesting materials while the environmental temperature was between 25C 32C. The pH was within the range 4.8 - 6.8. A total of twelve bacteria, five fungi and one yeast were isolated during digestion of materials. The chemical composition of the gases of water hyacinth and pig dung in ratio of 1:1 were 83.40% methane, 0.01% ammonia, 0.03% carbon dioxide, 1.86% carbon monoxide, 5.85% hydrogen sulphide and 8.89% other gasses. The ratio 1:3 were 88.3% methane, 0.04% ammonia, 0.02% carbon dioxide, 1.30% carbon monoxide, 4.10% hydrogen sulphide and 6.20% traces of other unknown gasses. There was increase in the percentage composition of the methane gas when the water hyacinth was just in ratio one and pig dung ratio three, that is the lower the water hyacinth the more will be the methane produced.
