The effect of bioactivator formulation on nutritional quality and functional microbial content in goat feces biofertilizer

Abstract

Changes in lifestyle and the negative impact of chemicals make people aware of the dangers of consuming food products containing chemical residues so many people switch consuming organic food. Black rice is one of the kinds of rice that is widely consumed as an organic functional food because of its antioxidant and dietary fiber content. Black rice has been rarely cultivated because it longer harvests age and lower productivity than white rice. The way to increase the production and quality of black rice is by applying manure or biofertilizer, which contains the nutrients needed by plants. This study aimed to find bioactivator formulation that has the highest nutrients and functional microbes’ content in biofertilizer. This study used a completely randomized design with five bio activator treatments: Bacillus, Trichoderma, Saccharomyces, Bacillus + Trichoderma, Bacillus + Saccharomyces, which have replicated three times. The results showed that the bio activator formulation had a significant effect on the total bacteria, very significant effect on the organic C content, total N-fixing bacteria, P solubilizing microbes, N and P content.
