This study evaluates the economic viability of using ASD in tomato production drawing on data produced by two field experiments conducted at the University of Florida Southwest Florida Research and Education Center (SWFREC) in Immokalee and the Plant Science Research and Education Unit (PSREU) in Citra, FL in fall 2015. Each location had one CSF and two ASD treatments in a randomized complete block design. The CSF treatment used Pic-Clor 60 at the rate of 224 kg/ha at both locations. The two ASD treatments used different rates of molasses and CPL, 6.93 m3/ha molasses and 11 Mg/ha CPL were applied for ASD0.5, 13.86 m3/ha molasses and 22 Mg/ha CPL were applied for ASD1.0. The economic analysis focused on differences between the CSF and ASD treatments with regard to land preparation cost, gross return and net return. The land preparation cost per plant was $0.35- $0.38 in CSF and $0.74-$1.31 in ASD treatments. Two ASD treatments in Immokalee generated higher net return than the CSF treatment. Although the commercial viability on ASD in Citra was not obvious, we can still get profit if we sell the Citra’s tomato at Immokalee’s price. The planting date was not the most concerned factor. However the market tomato price changed a lot as time changing. In conclusion, ASD increased yields and can be an economically viable tomato field production method in Florida in most cases.
