P8666 Maize Silage Hybrid

Grows well, yields very well and feeds even better.

A bulky plant with superior early growth, drought tolerance and strong all-round agronomics.

  • Produces silage with high grain content that cows will thrive on.
  • Plant to establish 100,00 to 115,000 plants per hectare.
  • Companion with P8532.

Widely adapted from Ashburton to Dargaville.

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.
