P8333 Maize Silage Hybrid

Highly productive mid-maturity option.

P8333 is a tall bulky plant with a long grain filled ear, supported by strong all-round agronomics, superior drought tolerance and staygreen.

  • Delivers top silage yields for maturity, with impressive energy and digestibility.
  • While earlier than P8666 it has similar in-paddock appearance.
  • An important mid-maturity option between P8000 and P8500.
  • P8333 is a tall leafy plant, so optimum established populations should be approximately 5,000 per hectare less than applied for P8000 and P8500.

Yields particularly well in the South Island and in the cooler regions of the Lower North 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 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.
