P0640 Maize Silage Hybrid

Leaf disease champion delivering silage yield stability.

A balanced all-round hybrid with desirable leaf disease resistances.

  • Tall plant with sound standability, staygreen and drought tolerance.
  • Superior resistances to Northern Leaf Blight and Rust for notable mid to late-season plant appeal.
  • Produces silage with superior digestibility and energy content.
  • Provides yield stability in moderate to high yield environments from Northland to Waikato, Bay of Plenty and East Coast.

Plant with P0362, P0900 and P0937 depending on maturity requirements.

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.
