Abstract
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.
