Publication Date : 24/06/2018
Environmental pollution is the major threat confronting the world and the rampant use of chemical fertilizers and pesticides can contribute to the deterioration of the environment. This ill-practice can lead to loss of soil fertility which may have a huge impact on agricultural productivity. Vegetable wastes provide a good amount of nutrients for inhabiting microbes and thus can be a potential alternative for transforming into an organic biofertilizer. Therefore the present research work was undertaken to formulate the vegetable waste compost in association with microorganisms (Rhizobium spp., Azotobacter spp. and Lactobacillus spp.) and Spirulina that can act as a potential biofertilizer and its comparative assessment with synthetic fertilizer. The formulated compost mixtures were inoculated with variant combinations of organisms, Test Control and Control. These microbial cultures were combined with different combinations of vegetable wastes like corn and cabbage, cabbage and onion, corn and onion with soil which were utilized to formulate into a potential biofertilizer. It was observed that there was increase in shoot length (24.4cm) and root length (6.0cm) in the consortium treated plant in combination with corn+onion. The comparative assessment undertaken in the current study gave the major outcome that the formulated biofertilizer was better than the synthetic fertilizer and hence can serve as the potential substitute to the hazardous chemical or synthetic fertilizer. Towards the end the positive outcome substantiated that microbial biotechnology can be a powerful tool for the decomposition of kitchen waste into a value added material.
