Field experiments were conducted at the University of Florida Indian River Research and Education Center, Ft. Pierce, FL in the Spring 2001, Fall 2001, and Spring 2002 seasons. For each of these experiments, tomato transplants were grown from seeds in polystyrene trays. Approximately one month later, transplants were set into raised,plastic-mulched beds formed from Oldsmar fine sand soil on the research center farm. Beds were spaced 2.1 m apart center to center with seedlings 61 cm apart within rows. A seepage irrigation system was used in all tests. Transplants received an application of the insecticide imidacloprid in the transplant water at 0.42 kg a. i./ha, primarily for control of the whitefly, BemIsia argentifolii Bellows & Porring. An application of 4–16–4 (NPK) fertilizer was broadcast at 770 kg/ha and incorporated into beds. An additional 1537 kg/ha of 8–12–20 (NPK) fertilizer was applied as two bands near the shoulders of the bed just prior to coverage with plastic mulch. Dolomite (2.7 metric tonnes/ha) was applied as needed to help prevent fruit loss from blossom-end rot. Insect pests and interbed weeds were controlled as needed (POHRONEZNY et al.1986).
