P9978 Maize Silage Hybrid

Defensive. Stable. Productive.

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, staygreen and Northern Leaf Blight resistance.
  • Delivers top silage yields, in this maturity, with excellent feed quality.
  • When planting early or into cold wet soils switch to P9650 or P9911.

Now widely grown in 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.
