SL346: A Summary of N, P, and K Research with Potato in Florida

Figure 9. Potato yield versus N rate for more recent studies that included at least 3 levels of N, with other nutrients held constant. These values are the same data as in Figure 7, but here the actual yield in cwt/acre instead of the percent relative yield are presented. The first 11 studies were Hochmuth et al., 1993b; Other reports are Chen and Hutchinson, 2008; Pack et al., 2006; Hutchinson, 2005; Hutchinson et al., 2003; and Munoz, 2004.
