Soils in arid regions are very poor in organic matter content. The application of , municipal compost enhances crop yield by improving soil physical and chemical Conditions. A field study using a completed randomized block design in four replicates was conducted. The factorial combination of 0, 25, 50 ton/ha municipal compost and 0, 60, 120 kg/ha Nitrogen was used with sugarbeet- . wheat rotation in permanent plots for two years. Compost analysis showed that the lead level was higher than the permissible level. The effect of compost treatment especially in the second years was significant on sugarbeet and wheat yield (p 0.01). Due tohighN-N03 in irrigation water, the effect of Nitrogen levels on yield was not signified. The effect of municipal compost on availability of P, K, Fe, Zn, Cu and Pb in soil were significant
