Graduate research assistant Akeza N. Germaine of Kentucky State University recently showcased her work on advanced lighting technologies for crop production at the CEA Ag World Conference in Durham, North Carolina.
Germaine presentation, “Lighting for Quality: Boosting Crop Nutrition and Efficiency with Advanced LED Strategies,” explored innovative methods to enhance both the nutritional value and market appeal of crops grown in controlled environment agriculture (CEA) systems.
Germaine’s research centers on the use of targeted LED light spectra, particularly red LEDs at 660 nanometers, to improve the nutrient content of tomatoes and leafy greens. She discussed techniques such as intra-canopy lighting and carefully balanced red and blue light combinations to increase phytonutrient levels, elevate crop quality, and maximize energy efficiency.
In addition to lighting strategies, Germaine highlighted the need to pair advanced illumination systems with precise irrigation and nutrient management. This integrated approach supports the production of premium, nutrient-rich crops while ensuring responsible resource use in greenhouse and indoor farming environments.
Working in Kentucky State University’s Urban Agriculture/Controlled Environment Agriculture Lab under the direction of Dr. Theoneste Nzaramyimana, Germaine studies how artificial lighting influences phytonutrient accumulation in dwarf tomatoes.
“Ms. Germaine is a highly dedicated young scientist whose work in my Urban Ag./CEA Lab continues to advance understanding of how LEDs light, nutrients, and crop physiology interact in indoor production systems,” said Dr. Theoneste Nzaramyimana.
“Her attention to detail, strong analytical skills, and commitment to producing meaningful, applied research make her an outstanding contributor to our lab and to the future of sustainable food production.”
Before presenting at the conference, Germaine attended the 4th Annual Controlled Environment Agriculture Summit East in Danville, Virginia, supported by the 2025 Cooperative Extension Scholarship.
“I’m grateful for the opportunity to share my work and learn from experts in the field,” Germaine said. “The Urban Ag/CEA Lab at Kentucky State University has been instrumental in guiding my research and professional growth.”
