MANAGEMENT OF DIFFERENT TYPES OF WASTES BY VERMICOMPOSTING USING EARTHWORM VARIETIES.

Abstract :

Vermicompost is an eco-friendly fertilizer, have an important contribution to agriculture.It have higher level of available of macro and micro nutrients like as carbon, nitrogen, phosphorous, potassium, calcium and magnesium derived from the wastes. These wastes include industrial, agricultural plant debris and domestic waste such as paper waste, cattle dung. Hence the present study was planned by use of three varieties of earth worms were used such as Eisenia foetida, Eudrilus engeniae and Perionyxexcavates.The wastes namely paper cattle dung and plant debris are rich in carbon while deficient in nitrogen so Cow dung was mixed with it to make it suitable for three earthworms.A mixture of waste paper, plant debris and cattle dung mixed in the ratio of 1:1 and designed asT1, T2, T3, control. A significant difference was detected among weight and number of earthworms in the treatments, which the highest weight and population growth of worms occurred in T1-60% of paper waste, T2-50% of plant debris, T3-30% of cattle dung.After 90 days time excellent quality and quantity of compost was produced by the three earthworms. Physical and biochemical parameters were analyzed before and after treatment. After treatment the parameters like, total nitrogen (0.5-1.50%) Phosphorus (0.1-0.30%) and exchangeable potassium (0.15- 0.56%) was increased Compared with three earthworm varieties of Eisenia foetidashowed better degradation of all the three types of wastes, especially paperwaste. This study clearly indicated that vermicomposting is a suitable technology for bioconversion of newspaper waste, Cow dung and plant debris to valuable organic rich manure.
