The research objective was to determine the interaction effect of water hyacinth compost and sewage water on the growth and production of mustard greens. This research was carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jalan Kaharuddin Nasution No. 113 Air Cold Village, Bukit Raya District, Pekanbaru City. This research was conducted for 2 months from October – November 2022.

The treatment combination was repeated 3 times. Thus, there will be 48 experimental units. Each experimental unit contained 6 plants and all of them were used as observation samples. So that the number of plants used for the entire experimental unit is 288 plants. Based on the results of the research that has been done, it can be concluded as follows: The interaction of water hyacinth compost and sewage water is significant for all observation parameters. The best treatment is the dose of water hyacinth compost 180 g/plant and 100% sewer water. The main effect of water hyacinth compost was significant on all observation parameters, where the best treatment was a dose of 180 g/plant. The main effect of real sewer water on all observation parameters. The best treatment is 100% sewer water. Keywords: Water hyacinth compost, sewer water, mustard greens
