Tea (Camellia sinensis) and Arabica coffee (Coffea arabica) are main economic
crops in the northern region of Vietnam, contributing for improving income of local
farmers. However, the production activities of these crops in Vietnam are depended on
agrochemical to maintain crop productivity that has led to many unexpected consequences
on the environment, ecosystem, and human health. The potent enzymatic producing fungi
were found, screened and developed to be biofertilizer product and used for tea and arabica
coffee cultivation. Chaetomium PT2, Trichoderma DB, Mucor PT1, Cunninghamella SL2,
Penicillum TN1, AspergillusPT were selected and all tested isolates produced cellulase,
xylanase, and ligninase to degrade organic materials. Those isolates were developed to be
organic biofertilizer product (BFP). In vivo trial, results in a greenhouse experiments
showed that the bio-fertilizer product not only gave significant effects on growth of tea and
coffee plants but also increased the organic matter in soil. The bio-fertilizer product could
provide a good choice to apply on tea and coffee plants in Vietnam to decrease the
application of chemical fertilizers.
