ABSTRACT
Brinjal farming appears to be benefiting from Integrated Nutrient Management, that utilizes integrated application of chemical fertilizers and organic fertilizers produced from agricultural waste. In the present study, probiotic microorganisms Lactobacillus and Saccharomyces were used to ferment nitrogen, phosphorous, and potassium-rich agricultural residue into organic liquid NPK fertilizer. The effectiveness of this process was tested on brinjal under field conditions. Nine distinct agricultural wastes were combined to create 27 factorial formulations that had one N, P, and K-rich substrate and subjected to microbial fermentation in 1 L flasks.
