Vegetable Crop Physiology and Production Systems

Welcome to the Vegetable Physiology and Production Systems Research Lab at Mississippi State University. We conduct studies that blend applied and basic research to provide science-based vegetable management recommendations to field and greenhouse growers in Mississippi and the southeastern U.S. Our research program focuses on examining plant physiology of vegetable crops with the ultimate goal of delivering novel and improved vegetable management strategies.

Specifically, our goals are to maximize nutrient and water use efficiency, increase the adaptation to environmental stress (light, temperature), maintain or improve the quality and nutrition for consumers, and ultimately enhance the economic return for farmers and industry in the ‘local and farm to table’ chain.

We have a number of great projects we are working on for our stakeholders. Feel free to contact us to discuss our activities or if you have any questions regarding our research and extension program. You can also follow our projects by clicking the research and extension menu, or by going straight to our lab Facebook pages and Twitter feed (links below).


  • Tomato Nitrogen Rate Study

    Introduction: The standard recommendation for tomatoes from the Mississippi State University Soil Testing Lab is 120lbs of actual Nitrogen per acre (N/ac). A number of Mississippi growers and extension agents have questioned if this was adequate. In the 2014 Vegetable Crop Handbook for Southeastern United States 200. 5lbs of N/ac is the recommended rate. This study was conducted to determine yield differences from the Nitrogen rates of 0, 50, 100, 150, and 200lbs N/ac applied in split applications to 3 tomato varieties, field grown in north Mississippi.
