\textbf{Abstract}
\begin{abstract}
\normalsize{
In recent years disregard for sustainable agriculture caused a sharp decline in soil organic matter content in Iran, as in most parts of the country soil organic matter is less than one percent. On the other hand the large volumes of urban waste and the high disposal costs of it would be a big challenge for the future. Therefore, using municipal solid waste compost in agriculture could be a major step forward in achieving sustainable agriculture and reduction of the adverse effects of chemical fertiliser and conventional agriculture methods in Iran.



This experiment was conducted in order to study the influence of municipal solid waste compost and nitrogen on grain quality and quantity of sweet corn and some soil properties and also to find the best combination of chemical and organic fertiliser on sweet corn at Marvdasht district.



The results showed that the effect of compost was additive and significant on soil nitrogen, phosphorus, potassium and soil organic matter, as these results reflect the positive effects of municipal solid waste compost on chemical properties and soil organic matter, also these positive effects can justify the negative impacts resulting from the use of compost such as increase of soil electrical conductivity and accumulation of heavy metals. 



Other results were indicative of positive effects of compost on ear and grain yield, as the yield was increased by adding the amount of compost from 10 to 40 tons per hectare in low levels of nitrogen. It was found that, with regard to the results, to achieve to an optimum yield of sweet corn, we can reduce \mbox{100\,kg} of nitrogen by using 40 tons of compost per hectare, as the yield in treatment of \mbox{200\,kg} nitrogen plus 40 tons of compost had no significant difference in comparison to the yield of treatment of \mbox{300\,kg} nitrogen per hectare (the recommended nitrogen based on the soil analysis). The total result of the experiment is representative of the high ability of municipal solid waste compost in providing soil organic matter content and essential nutrients to plants growing.
