They are few reports on the effect of municiple compost on the soil properties, quality and quantity of sugarbeet. The aim of this study was to obtain information about municipile compost on the soil properties , quality & quantity of of sugarbeet. A field study was conducted at Baraan Rsearch Station with sugarbeet-wheat rotation in permanent plots. The experimental design was factorial combination with 0, 25 & 50 ton/ha municiple compost and 0, 60 & 120 kg/ha nitrogen at four replication. Compost chemical analysis showed that the lead level was higher than the permissible level. The effect of municiple compost was significant on P, K, Fe, Zn, Cu & Pb in soil. At the second years the effect of nitrogen wasn’t significant on root and sugar yield, because of high N-NO3 in irrigation water. Application of municiple compost is not recommended befor planting of sugarbeet ,because of increase soil nitrate content decrease of sugar yield.
