P8240 Maize Silage Hybrid

Bulk and energy to fill the vat.

P8240 is a tall, high-yielding silage and grain hybrid backed by strong drought tolerance, staygreen and standability. 

  • Delivers top silage yields, with superior feed quality for optimal milk production.
  • P8240 has a balanced agronomic package while noting superior roots are a real asset in this maturity.
  • Established plant populations should be matched to assessed paddock yield potential. 
  • Plant with P8000 or P8333 depending on maturity requirements. 

Widely adapted to Central Plateau, Taranaki, Lower North Island and South Island growing regions.

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.
