Abstract

This research was conducted with four treatments ; 1: control , 2:USW compost (20 ton/ha) , 3: sulfur (1 ton/ha) ,4:mixture of USW compost and sulfur (sulfur10% of compost used), each treatment with four replications to study the effect of urban solid waste compost (USWC) and sulfur on soil chemical and yield of sugar beet under field condition .Data collected was analyzed in Randomized block design (RBD) and treatment means compared by using Duncan test at p =0.05 . Results indicated that crop biomass yield in USWC treatment was highest. Maximum root yield was obtained in USWC, sulfur, USWC + sulfur and control respectively .Soil pH in USWC + sulfur and sulfur treatments were minimum, probably, due to the acidic nature of both materials used. EC of soil in USWC + sulfur treatment was highest compared to other treatments. Organic carbon of soil in USWC and USWC + sulfur treatments were highest. Soluble cations of potassium, calcium and magnesium in USWC + sulfur and sulfur treatments were found maximum, but soluble sodium was highest in USWC treatment. Soluble anions of sulphate and chloride were highest in USWC + sulfur and sulfur treatments. Soil total nitrogen was highest in USWC + sulfur and sulfur treatments compared to others.
Soil phosphorus was highest in USWC, sulfur and USWC + sulfur, respectively. USWC + sulfur and sulfur treatments enhanced plant macro nutrient elements availability and uptake.
