This study was conducted to evaluate the effect of Municipal waste compost leachate (MWCL) on Capsicum annum plant and chemical properties of a clay loam soil with five ratios of MWCL to irrigation water (0, 20, 40, 60 and 100 percent) treatments each with three replications by using a completely randomized factorial design under greenhouse condition. Electrical conductivity, organic matter and concentration of available nutrients of N, P, K, Ca and Mg in soil increased with increasing percentage of MWCL, but pH of the soil was decreased. Increased concentrations of MWCL caused drastic decreases in plant growth. The MWCL of 100 percent treatment caused the seedlings to be died off. The treatment with 20 percent MWCL increased plant fresh and dry weight, fresh and dry weight of green chili. Plant content of N, P and K increased with increasing concentrations of MWCL. The use of 20 percent MWCL seems to cause increasing green chili yield. A application of high concentrations of MCWL to soil is not recommended due to increase of EC of soil solution.
