P7647 Maize Silage Hybrid

Delivers superior yields of top-quality silage.

Expands the options for cooler maize growing regions.

  • Combines strong early growth and staygreen to deliver silage with excellent energy and digestibility ratings.
  • Trials show P7647 is quicker to reach harvest drymatter and is higher yielding than P7524 which it replaces.
  • Tall for maturity so should be planted to achieve plant populations between 105,000 and 115,000 plants per hectare depending on paddock yield expectation.

Important option for South Island growers looking for a hybrid maturity between P7364 and P8086.

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.
