A recent study published in Vegetos by researchers from Chaudhary Charan Singh Haryana Agricultural University, Hisar, India, unveils novel microbial strains with exceptional biofertilizer potential.
The study, titled “Evaluation of Plant Growth-Promoting Traits in Azotobacter and Trichoderma Strains Isolated from Natural Farms in India,” focuses on isolating beneficial microbes from organically managed farms—an underexplored agroecological niche.
From the collected samples, 22 bacterial and 16 fungal isolates were screened. The researchers identified 12 Azotobacter and 8 Trichoderma strains as strong candidates after a rigorous two-step morphological and biochemical evaluation. Key plant growth-promoting traits such as indole acetic acid (IAA), ammonia, hydrogen cyanide (HCN), siderophore production, and mineral solubilization were analyzed.
Among the isolates, Azo 11 and Azo 12 were identified as Azotobacter chroococcum, and BNT 2 and BNT 8 were identified as Trichoderma asperellum and T. harzianum, respectively. These strains demonstrated multiple beneficial traits, including nutrient solubilization, enzyme production (amylase, lipase, laccase, cellulase), and biocontrol potential.
The multifunctional nature of these microbes highlights their suitability as eco-friendly biofertilizers capable of enhancing soil fertility, nutrient uptake, and plant resilience—critical for low-input sustainable farming. The authors emphasize their application in natural farming systems to reduce dependence on synthetic fertilizers and pesticides.
This research offers a significant step toward integrating microbial biotechnology into mainstream organic agriculture, marking a promising direction for India’s sustainable food security initiatives.
