Abstract: The term bio-fertilizer is made up of two words “Bio” means living and “Fertilizer” means a product that provides nutrients in usable form. But as a product Bio-fertilizer does not contain any significant quantity of nutrients itself. It contains mainly live bacterial or fungal cells, which on application helps in fixing or solubilizing the nutrients present in air or in soil. These are natural fertilizers.
Keywords : Bio-fertilizers, Horticultural crops
