The blind use of fertilisers have made the soil dilapidated to such an extent that it would take 3 years of no cultivation and continuous fixing of minerals by organic methods, to convert the soil for the purpose of organic farming. Chemical fertilisers are like a drug to the soil, the more we use the more will be required. In order to bring a change and to make organic method more demanding and handy, a set of trials were done. The experiments were conducted inside the college campus using different type of manures, farm yard manure (made by cow dung straw and cow urine), garden manure (made by dry shredded leaves, kitchen waste and thrown flowers) and vermicompost (using Eisenia fetida earthworms) made by easy composting in normal pressure and temperature and were tested on mangifera indica (mango) plants. Significant effects were observed on the plant yield. The use of lactobacillus serum alone has increased the yield significantly. Field studies evaluated the use of leachate along with the green manure. The study was done on the optimum use of manure for the nutrition requirement of plant.
