Abstract :

This research was done in biosystem Lab of the Islamic Azad University, Science and Research Branch in 2013. All the exams were done by mixed statistic model. Different mixtures of three main groups were chosen to produce compost including fruit peels and vegetables, plant leafages and other organic materials exist in municipal solid wastes as the independent variable. Salinity, potassium and nitrogen content and also dill dried weight (grown in different compost product treatments) were considered as the dependent variables. The results showed that different mixtures of the raw materials in compost production have meaningful effects on the quality and chemical characteristics of compost and dill function. So the best scenario in the mixture of raw materials for dill with regards to the objectives of function optimization is nutritional elements in compost, mixture of all raw materials and the desirability of the object function and also minimization of the compost salinity from the mixture of 65.6% of fruit peels and vegetables with 34.4% of plant leafages produced from municipal solids.
