Growth Stages and Tuber Development of FL1867 Potato under Full and Reduced Irrigation Scheduling

Figure 1. Whole plant samples of FL 1867 during the 2012 growing season at 41 DAP (A), 48 DAP (B), 54 DAP (C), 61 DAP (D), 75 DAP (E), and 90 DAP (F).The potato cultivar ‘Frito Lay 1867’ (‘FL 1867’) is a popular chipping variety grown across Florida and the southern United States. Knowledge of the timing and duration of the tuber initiation and tuber bulking stages for ‘FL 1867’ is critical for timing fertilizer and irrigation applications. So to evaluate the start and length of the tuber initiation and tuber bulking stages under Florida growing conditions, ‘FL 1867’ plants were dug up and photographed on a weekly basis from a commercial field near Live Oak, FL in 2012. This 3-page fact sheet was written by Seth A. Byrd, Diane L. Rowland, and Lincoln Zotarelli, and published by the UF Department of Agronomy, September 2014.
