| a Total yield represents three harvest dates in 2009 | ||||||||||||
| b Stands were greatly reduced over the past season due to a hard winter and very wet spring. | ||||||||||||
| c PLH Injury scale 1=slight to 5=severe. | ||||||||||||
| Note: No insecticide was applied to this trial in 2011. Variety means are LSMEANS derived from nearest neighbor statistical analysis. | ||||||||||||
