In a major stride toward sustainable agricultural innovation, Gift Maureen Obunukwu, a plant pathologist and microbiologist, has emerged as a pivotal figure behind a transformative fertilizer initiative at Nigeria’s Federal Institute of Industrial Research, Oshodi, (FIIRO). Her leadership in the development and pilot deployment of a bio-enhanced fertilizer blend is not only improving soil health but also significantly boosting yields for smallholder farmers across Nigeria.

Under Ms. Obunukwu’s direction, the project focused on creating a cost-effective, eco-friendly fertilizer fortified with plant-growth-promoting rhizobacteria (PGPR) and organic inputs. Designed for use in both staple and horticultural crops, the fertilizer has shown promising results in experimental trials across key agricultural belts in Nigeria.

Indeed, pilot programs in Kaduna, Ogun, and Enugu states revealed a 25–35% increase in maize and tomato yields, as well as improved soil microbial activity. For resource-poor farmers, this translated into shorter crop cycles, better resistance to disease, and lower input costs due to reduced chemical fertilizer dependence.

Ms. Obunukwu’s background in endophyte-microbe interactions and plant pathology was critical in tailoring the bio-fertilizer to Nigerian soil conditions. Her approach ensured that the formulation was compatible with indigenous cropping systems and could be locally produced, cutting down the need for costly imports.

Farmers have already begun to see the difference. Mrs. Amaka Eze, a tomato farmer in Nsukka, shared:

“Before using the FIIRO blend, my yield barely supported my family. This last harvest, I sold over 30% more produce than usual. I’m now able to save and plan for the next season.”

The success of the fertilizer initiative has also drawn the attention of government stakeholders. Talks are underway to scale production through public-private partnerships, and the National Agricultural Seeds Council has commended the work for aligning with Nigeria’s Food Security Roadmap.

Beyond the lab and test plots, Ms. Obunukwu continues to advocate for sustainable, science-based farming solutions. She regularly trains extension agents and collaborates with university researchers to refine biotechnological applications in agriculture.

As Nigeria works to secure its food systems in the face of climate change, soil degradation, and population pressure, innovations like this fertilizer blend—led by young scientists like Gift Maureen Obunukwu—are proving that homegrown solutions are not only possible but powerful.
