Jessica G. Davis

davisDepartment Head

115 Shepardson


As department head, I am responsible for all strategic, operational, financial and human resource activities of the Department of Horticulture and Landscape Architecture (HLA), as well as serving as a contributing member of the leadership team for the College of Agricultural Sciences.

Research Interests:

My research focuses on development of fertilizers and soil fertility management approaches that optimize plant and human nutrition while protecting environmental quality. Nitrogen fertilizer is estimated to contribute about two-thirds of greenhouse gas emissions attributed to crop production. But without fertilizers, crop yields would be halved, a loss that humanity cannot afford. Therefore, we have been working towards development of fertilizers that can be produced locally, moving towards a truly local agriculture and avoidance of fossil fuel usage during shipping. Current research is focused on tree fruit and vegetable production systems.

Courses I Teach:

I am currently revising AGRI 192/292 and conducting a series of tours for our new undergraduate students to get to know the People and Places of HLA.

I coordinate HORT 792 Graduate Seminar.

In addition, I am the Coordinator of the Peace Corps Masters International Program for the College of Agricultural Sciences. This Master of Agriculture degree program combines coursework with 2 years in the Peace Corps to provide students with applied international experience while pursuing a graduate degree.

Extension and Outreach:

The HLA department has a diverse group of stakeholders. I am developing a Stakeholder Advisory Team with whom I will meet regularly in order to guide our teaching, research, and outreach activities.
