Conventional varieties were evaluated using a total of 185 lb of N applied in a three-way split with or without fungicide (8 oz Quadris plus 6 oz Tilt) at late
boot. Ratoon received 135 lb N in a single preflood application plus 8 oz Quadris and 2 oz Karate at late boot.
2
Hybrids were evaluated using either 90 or 120 lb N applied all preflood and supplemented with 60 lb N at late boot to early heading. Hybrids received no
fungicide. Hybrid ratoon received 135 lb N in a single preflood application.
