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.

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.

IMPORTANT NOTE: Hybrid comparisons are only valid within a range of + or - 4 CRM. These descriptions mainly feature product strengths. When choosing hybrids, also review carefully the trait ratings found in the table here. Contact your local Pioneer Area Manager or merchant representative for further advice.
