Under shed at Biogas Research and Extension Centre, Gujarat Vidyapith, Sadara, District- Gandhinagar, Gujarat, India, a composting pit was prepared by bricks and filled with mixture of 10 kg dung (2.5 kg each of cow, buffalo, sheep and goat) and 2 kg leaves of Calotropis gigantea. The mixture was well mixed at 15 days interval and samples were analysed for various physico-chemical properties at monthly interval of composting upto 90 days. Results show that compared to values of various physico-chemical parameters before composting the values of available phosphorus, available potassium and total nitrogen increased by 2.89, 2.18 and 3.15 times whereas content of pH, electrical conductivity, chloride, total organic carbon and ratio of C:N decreased by 1.12, 4.13, 2.68, 2.38 and 8.13 times after composting. The study highlights the conversion of leaves of C. gigantea into valuable compost.
