Soybean Planting Time Research Earns Kentucky State Graduate Student Second-place Honor At ASA Southern Section Meeting

With Kentucky farmers weighing tighter planting windows and shifting growing conditions, graduate student Anjan Timilsina is helping refine management decisions that can shape both yield and seed quality.

Timilsina, a Kentucky State University graduate student, earned second place in the master’s student poster competition at the American Society of Agronomy’s Southern Section annual meeting, held Jan. 31–Feb. 3 in Louisville, Kentucky.

His poster, “Identifying optimal planting date for different maturity groups for soybean cultivars in Kentucky,” examined how planting date and maturity group influence yield and seed composition under Kentucky growing conditions. The work supports improved recommendations for producers as weather patterns and production conditions continue to evolve.

“This experience provided a valuable opportunity to present my research to agricultural professionals and receive constructive feedback,” Timilsina said. “I am very grateful for the mentorship and continuous support of my advisor, Dr. Anuj Chiluwal, and for the research environment at Kentucky State University.”

A second-year master’s student in Environmental Studies, Timilsina, joined Kentucky State in January 2025 under the supervision of Dr. Chiluwal. He earned a Bachelor of Science in agriculture from Tribhuvan University and previously worked as an agriculture instructor and farm manager in Nepal, gaining more than three years of hands-on experience. He is dedicated to field-based research aimed at supporting rural communities, addressing climate challenges in agriculture, and strengthening food security.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
