Fig. 1. The effects of various fertilizer treatments on total dry matter (DM) yield of stargrass in 1998, 1999, and 2000. Total DM yields in a specific year with letters in common are not significantly different (P > 0.05). Minimum significant differences (MSD) are 0.415, 0.466, and 0.639 for years 1998, 1999, and 2000, respectively.
