Dr. Torres current emphasis is the evaluation of production practices that maximize plant yield and quality while minimizing the detrimental effects of abiotic stressors. Currently, his research efforts focus on water and nutrient management, and cultural practices for vegetables, soil fumigation practices, and integration of precision agriculture practices in vegetables, both in open field and under protective structures.


Dr. Torres extension philosophy is based on the idea that an extension program should do more than just share knowledge; it also should bring about real changes in practice. To make sure this happens, his program follows the “SMART Objectives” framework: Specific, Measurable, Achievable, Relevant, and Timebound. Here’s how his lab does it: First, they survey farmers to understand their needs. Then, they set clear goals aimed at making a difference. After that, they create a detailed plan and timeline to achieve those goals, and finally, they check back with the farmers to see if their efforts have made a difference. This way, his program not only teaches but also helps improve farming practices.


Dr. Torres teaches the Vegetable Production Class (HS431 – Hybrid) every fall semester, which focuses on fundamental production practices for multiple vegetable crops (tomatoes, pepper, potatoes, cucurbits, leafy greens, brassicas, among others). The class delves into the specifics of the history of vegetable crops, plant physiology, production techniques, and water and nutrient management. Students will also learn about differences between open field production and protective (greenhouse, tunnels) production, precision ag applications to vegetables, and sustainability in horticulture. Throughout the course, emphasis is placed on hands-on learning, fieldwork, and practical applications to equip students with the necessary skills and knowledge for successful vegetable production.
