Changes in colour and temperature during vermicomposting of different organic wastage

Abstract

In normal vermicomposting black colour indicated in vegetable market waste, very dark brown in soybean straw, dark grey in sugarcane trash and very dark brown in sugarcane trash + soybean straw. While in case of the modified vermicomposting black colour of vermicompost indicated in vegetable market waste, very dark grey in soybean straw, very dark grey in sugarcane trash and very dark grey in sugarcane trash + soybean straw. The result indicated that the temperature was recorded significantly higher in normal vermicomposting (M1) than modified vermicomposting (M2) at 15 to 60 days. In treatment the maximum reduction of temperature was recorded with vegetable market waste (T3) 24.83 0C over to soybean straw (T2) 27.17 0C, sugarcane trash + soybean straw (T4) 27.67 0C and sugarcane trash (T1) 28.67 0C at all days.
