Comparison of Bioproduct Quality from Vermiconversion of Spent Pleurotus sajor-caju Compost and Commercial Livestock Excreta

Vermiconversion study was conducted to compare the use of commercial livestock excreta i.e. cow dung (CD) and goat manure (GM) in the vermiconversion of spent mushroom compost (SMC) utilising red worms i.e. Lumbricus rubellus to obtain good quality compost with high nutrient content. This study was...

Noorlidah Abdullah, Vermiconversion study was conducted to compare the use of commercial livestock excreta i.e. cow dung (CD) and goat manure (GM) in the vermiconversion of spent mushroom compost (SMC) utilising red worms i.e. Lumbricus rubellus to obtain good quality compost with high nutrient content. This study was performed for 70 days after 21 days of pre-composting at different ratios of livestock excreta and SMC. The highest multiplication and growth of earthworms in number and biomass was recorded in TE with increment of +296.57 and +484.20%, respectively.

The results for non-mixed substrate showed, CD (TA) bioproduct obtained, contained the highest concentration in exchangeable K (1.98%).
