Emmanuel Torres Quezada
Dr. Emmanuel Torres Quezada is the Assistant Professor of Horticulture at the Eastern Shore Agricultural Research and Extension Center. He earned his bachelor's in Agriculture from the Universidad Nacional Pedro Henríquez Ureña in the Dominican Republic. Additionally, he received his MSc and PhD in Horticultural Sciences from the University of Florida, where he worked extensively on water management practice for strawberry. He also worked as an associate professor at the Pan-American Agricultural School Zamorano in Honduras, where he integrated his teaching and research program to promote innovative management practices for vegetables in Central America. His research focuses on production practices for vegetable crops in both open field and protective systems, with an emphasis on water management. Additionally, he is identifying potential applications of precision agriculture technologies to vegetable production systems.

My goal at the Eastern Shore Agricultural Research and Extension Center of Virginia Tech is to improve the efficiency and productivity of vegetables and small fruit systems in the Commonwealth of Virginia. The current emphasis of my laboratory is the evaluation of production practices that maximize plant yield and quality while minimizing the detrimental effects of abiotic stressors. Currently, my research efforts are divided into three categories with multiple projects within each group: 1. Conventional production systems for vegetables and small fruits, 2. Precision agriculture applications to vegetable systems, and 3. New specialty crops and production systems.
- Conventional production systems for vegetables and small fruits:
Determination of crop coefficients for potatoes, tomatoes, and green beans in the Eastern Shore of Virginia.
Kaolin clay applications for heat mitigation in summer-grown tomatoes in Virginia.
Planting dates and N-rates interactions for potato production.
Evaluation of potato cultivars for the northeast USA.
Cover crop mixes for nematode management in potato production.
- Precision agriculture applications to vegetable systems:
Evaluation of crop indexes for determination of N rates in potatoes under different irrigation regimes.
Evaluation of Eddy covariance method and soil moisture sensors as determination methods for irrigation requirements in early spring tomatoes.
- New specialty crops and production systems:
Green tea: a new specialty crop in Virginia.
Determination of plant densities for tomatoes under open high tunnels in Virginia.
Compost applications for bell pepper production under high tunnels
New bed architectures for tomato and strawberry production in the southeast.
Integration of vegetable system and photovoltaic cells
The dissemination of information and improvement of farmers, Extension agents, and stakeholders’ production practices is essential to having a relevant and impactful Extension program. My extension philosophy is based on the idea that programs that result in increased knowledge without actual change in practice are compared to programs that do not increase knowledge at all. To achieve true changes in practice, my program follows the framework of "SMART Objectives": Specific, Measurable, Achievable, Relevant, and Timebound. We survey our farmers to understand the needs of the industry, we set specific goals that aim to create a change, we develop an execution plan designed to achieve the proposed goals, and we proceed to survey our farmers once more to measure the impact of our efforts.
