P8333 Maize Grain Hybrid

Highly productive option for cooler regions.

P8333 is a tall plant with a long ear, good husk cover, supported by strong all-round agronomics, superior drought tolerance and staygreen.

  • Has fast drydown, good test weight and raises the yield bar in this maturity.
  • While slightly earlier than P8666 it has similar inpaddock appearance.
  • An important mid-maturity option between P8000 and P8500.

Delivers much higher grain yields than P8000 in the cooler regions of the lower North Island and South Island 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 HM differences means the bolded hybrid was drier at harvest, negative HM 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.
