Final seeding population: Population in 000s ppa that is the ideal target for this hybrid. Where conditions are less favourable, move to the lower range of the population recommendations. Position: This refers to the best fit in your crop rotation: R = rotated corn acres; C = continuous corn acres. Plant height: S = short; M = medium; T = tall; VT = very tall Kernel texture: VS = very soft; S = soft; M = medium; H = hard Starch amount: 1 = low; 9 = high Early starch availability at harvest: 1 = least readily available; 9 = most readily available Herbicide Sensitivity Caution: avoid post-emergent application of Group 27 & 28 herbicides (e.g., Converge®, Callisto®, or Impact™) on Leafy silage hybrids. Leafy hybrids have shown increased injury after post-emergent application of Group 27 & 28 herbicides in comparison to other hybrids.
