P8666 Maize Silage Hybrid

Grows well, yields very well and feeds even better.

Delivers industry leading silage yields in this maturity.
 
  • Tall bulky plant with strong all-round agronomics, superior drought tolerance, Northern Leaf Blight resistance and eye catching staygreen.
  • Produces silage with high grain content and with optimal digestibility that cows will thrive on.
  • Established plant populations should be approximately 5,000 per hectare less than applied for P8500, P8711 and P8805.
Widely adapted from Ashburton to Dargaville, while delivering industry leading yields for maturity in the South Island.

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.

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.
