Abstract

The National Institute of Fundamental Studies (NIFS) developed Biofilm Biofertilizer (BFBF) in-vitro and it was tested for efficacy in paddy cultivation, progressing from controlled greenhouse experiments to large-scale field trials, conducted in collaboration with the Department of Agriculture (DoA) and other stakeholders. The outcomes of this research program have proven a substantial reduction of Chemical Fertilizer (CF) usage up to ca. 50% when combined with the BFBF applied at the rate of only 2.5 L/ha. With this fertilizer combination, the BFBF demonstrated the real and significant (p<0.05) crop yield improvement effects, boosting the yields on average ca. 25% compared to DoA's CF practices in the long-term extensive research. The widespread adoption of the BFBF across ca. 0.11 Mha of paddy cultivation in Sri Lanka revealed the practicality of its use. In conclusion, the BFBF integrated an eco-friendly fertilizer technology into commercial-scale paddy cultivation. As such, the BFBF stands out as a sustainable and transformative solution, providing a blueprint for future agricultural innovations with global implications. This research program serves as a testament to the vital role played by fundamental research in driving a meaningful change for the benefit of agriculture.
