P9978
P9978 Maize Silage Hybrid
Very productive. Very stable. Very defensive.
P9978 delivers a great all-round package with superior foliar health and silage eye-appeal.
- Tall plant with low ear placement, strong roots and stalks, superior drought tolerance and staygreen.
- Provides comparable silage yields to P9911, however, P9978 is slightly quicker to harvest, has better standability, Northern Leaf Blight and Rust resistances.
- Delivers silage with higher energy and digestibility than P9911.
- When planting early into cold wet soils consider planting P9650 or P9911.
Widely adapted to all North Island growing regions where this maturity is required.

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.
