The second factor was delima corn. The variables observed for compost quality were C/N ratio, mineral content N, P, K, Ca, Mg, Fe, and  initial macro and micro nutrient of soil. Height and leaf area of plant, length, weigh, diameter of corn ear and weight of dry shelled were observed for growth and production of plant. The results proved that C-organic content, macro and micro nutrient in compost can increase organic substance, macro and micro nutrient of soil,improving plant growth and local corn production. Ela sagu compost can remedied sandy soil. The higher dosage until 15 ton per hectare of the compost the higher of growth and productionof corn.
