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

star 1 star 2 star 3 = very highly significant yield advantage to Pioneer

star 1 star 2 = highly significant yield advantage to Pioneer

star 1 = 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.
