In a significant stride towards sustainable agriculture, researchers from An Giang University in Vietnam are exploring the role of endophytic diazotrophic bacteria (EDB) in reducing nitrogen fertilizer use while boosting corn yields. Led by Nguyen Van Chuong from the Department of Crop Science, this study sheds light on how these beneficial bacteria can not only improve soil fertility but also enhance crop quality, paving the way for more environmentally friendly farming practices.
The research, conducted in the AGU greenhouse, tested two strains of EDB: Bacillus sp. NTLG2-20 and Bacillus arybhattai strain CM44. By examining the impact of these bacteria alongside varying ratios of urea fertilizer, the team discovered some promising results. “We found that the fresh cob yield from Bacillus A was 4% higher than Bacillus B, and a notable 12.7% higher compared to non-inoculated plants,” Nguyen noted. This suggests that incorporating these bacteria could be a game-changer for farmers looking to maximize their yields without over-relying on chemical fertilizers.
The findings are particularly relevant for those farming sandy loam soils, which often struggle with nutrient deficiencies. The study revealed that a 50% reduction in urea application, when combined with EDB inoculation, yielded results comparable to the full recommended dose of urea. “This indicates that we can maintain high productivity while cutting down on synthetic fertilizers, which is a win-win for both the environment and farmers’ wallets,” Nguyen added.
This research could have far-reaching implications for the agricultural sector. By reducing dependency on chemical fertilizers, farmers can lower their input costs and lessen the environmental impact associated with excessive fertilizer use. The potential for these bacteria to be developed into biological fertilizers opens up new avenues for commercialization. As farmers increasingly seek sustainable solutions, products derived from Bacillus strains could become a staple in modern farming practices.
The study, published in “Communications in Science and Technology,” underscores the importance of integrating biological solutions into traditional farming methods. As agriculture continues to face challenges from climate change and soil degradation, innovations like these could be crucial in shaping the future of food production. With ongoing research and development, we might soon see a shift in how crops are cultivated, leading to healthier soils and more resilient agricultural systems.
