Seepage irrigation is the most common irrigation system for potato production in Florida, which relies on control of the water table to irrigate the crop. A 2-year trial was established to evaluate the feasibility of drip irrigation as an alternative to seepage for potato production. The performance of 'Atlantic', 'Fabula', and 'Red LaSoda' varieties were evaluated by comparing two drip tape installation depths, surface (SUR) and subsurface (SUB) with seepage (SEP). The overall potato total yield was 25.3; 19.2 and 29.9 Mg ha(-1) for SUR, SUB and SEP, respectively. The SUR and SEP treatments yielded similarly for 'Fabula' in both years and 'Atlantic' in 2011. The 'Red LaSoda' consistently obtained lower yields under both drip treatments compared to SEP. Conversely, drip irrigation promoted significant reduction of the incidence of tuber physiological disorders such as brown center, hollow heart, and internal heat necrosis.
