The University of Florida, Institute of Food and Agricultural Sciences (UF/IFAS) is one of the Land Grant Universities in Florida, the other being Florida A&M University. The Land Grant Universities throughout the country have the mission to conduct teaching, research and Extension functions. The partnership between UF/IFAS and Florida Watermelon Association (FWA) has been strengthened in the past few years as evidenced by the increase in active watermelon research projects and the increase in educational opportunities at the FWA Annual Conference and other meetings throughout the state such as the Suwannee Valley Watermelon Institute held in Gainesville and the Tri-county Cucurbit Meeting held in the Panhandle area. Several of the UF/IFAS Research and Education Centers (RECs) throughout the state are hosting research trials for a wide range of topics important to the watermelon industry in Florida. Major watermelon research projects are being conducted by faculty at RECs in Homestead, Immokalee, Balm, Live Oak, and Quincy as well as the UF/IFAS Plant Sciences Center at Citra. In most cases, as research projects are being developed, letters of support from FWA are submitted and strengthen the proposals knowing the industry is involved in the planning of the research and Extension activities. FWA has also directly funded research trials in recent years on topics such as vine decline, controlled release fertilizers, petiole sap testing, and developing in-field virus testing procedures and tools. FWA also offers a UF Research tab on the FWA website so members can easily find research trial results and the complete library of UF/IFAS electronic publications on watermelon.
The 17 research projects listed below and conducted over the past four years and upcoming years represent slightly more than $2.3 million in total funding from about 10 primary sources of funding.
Below is a summary of primary watermelon research projects conducted by University of Florida IFAS faculty over the past four years and updated January 2020 for the Florida Watermelon Association
