P8666
P8666 Maize Silage Hybrid
Grows well, yields very well and feeds even better.
- Tall bulky plant with strong all-round agronomics, superior drought tolerance, Northern Leaf Blight resistance and eye catching staygreen.
- Produces silage with high grain content and with optimal digestibility that cows will thrive on.
- Established plant populations should be approximately 5,000 per hectare less than applied for P8500, P8711 and P8805.

Scientific Designation
= very highly significant yield advantage to Pioneer
= highly significant yield advantage to Pioneer
= significant yield advantage to Pioneer
NS = not significant
CA = commercially acceptable
1 Positive DM differences means the bolded hybrid was drier at harvest, negative DM differences mean it was wetter.
2 A positive yield advantage means the bolded hybrid produced more yield, a negative yield advantage means it produced less.
