Fig. 2. Effect of preflood N rate, averaged across midseason N rates, on the (A) incidence and (B) severity of kernel smut of Cocodrie or LaGrue rice in five studies conducted at the Pine Tree Branch Station (PTBS) and Rice Research Extension Center (RREC) during 2001 (01) and 2002 (02). For the environment x preflood N rate interaction on incidence (A), the LSD(0.05) values to compare incidence among preflood N rates within an environment = 8.5% and between environments = 10.5%. For the environment x preflood N rate interaction on severity (B), the LSD(0.05) values to compare severity among preflood N rates within an environment = 0.5% and between environments = 0.7%.
