ABSTRACT:

Microorganisms associated with the production of compost from cocoa pod wastes and animal dung was investigated for nine weeks. Cocoa pods were decomposed using animal dung (poultry droppings, pig and cow dung) in ratio 3:1 of cocoa pod to each of the animal dung. Cocoa pod and poultry droppings mixture has the highest bacterial, fungal and yeast population of 2.6 x106 – 2.9 x 106 (cfu/ml), 8.4 x105 – 9.2 x 105 (cfu/ml) and 4.0 x104 – 12.0 x 104 (cfu/ml). It also had the highest moisture content (88.81%) and temperature (350C) among the composting materials. The pH of decomposing samples ranged from 6.10 to 7.81 at the initial stage of decomposition and pH of 7.79-9.07 at maturity.Bacillus spandEcherichia coli had the highest percentage frequency of occurrence of 11.7% while Micrococcus sp and Lactobacillus sp had the lowest occurrence of 2.6% during decomposition. Poultry compost has the highest NPK (nitrogen, phosphorus and potassium) content of 1.345, 7.955 and 23.016 (mg/kg) respectively. Using the cocoa pod and animals dung wastes for the production of compost helps to reduce environmental pollution.
