Mangoes are called the “King of Fruits" for its taste, nutrients and uses. The solid waste comprised of mango peel, stones, stalk, trimmings and fibrous materials constitute about 40-50 percent of total fruits waste of which 12-15 percent is peel, 5-10 percent is pulper waste and 15-20 percent is kernel. Significant quantities of mango peel are to be composted in a hot composting system is recommended by using fresh cow dung (3:1 ratio; 3 parts mango peel or waste : one part water) and 2.5% Urea dissolved in water. The compost heap is turned once in a week and should maintain 50% moisture. The manurial value of mango waste compost shows around 1.5% Nitrogen, 0.40% Phosphorus and 1.4% Potassium.
