چکیده

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.‎
