Ultra Early Maize - P7034

P7034 is a very early maturity hybrid with dent grain texture. FAO 180. Primary end use: forage, grain and biogas. P7034 is the first Pioneer hybrid of this maturity that has dent type grain.

It has been bred specifically for the cool maritime locations found in the UK. This hybrid flowers early and produces silage with a very high starch content and starch yield. P7034 is typical of dent hybrids which invariably yield more starch than traditional flint type hybrids.

Dent type starch degrades at a significantly faster rate in the rumen than flint type starch, especially just after ensiling. Due to its faster ruminal starch degradation rate silage crops of P7034 should be clamped last and fed first thereby improving the feeding transition from any old to new crop maize silage.

Hybrid characteristics:

  • Dent grain texture with fast ruminal starch degradability
  • Very high whole plant digestibility
  • Very high starch content
  • Early flowering

Grown in the open

  • Widely adapted to all but the coldest maize growing areas of the UK, Ireland, Denmark and Sweden.
  • Ensile last and feed first.

Grown using the Samco System

  • P7034 will produce silage of a very high starch content and a very high starch yield.
  • P7034 can br grown in southern Finland using the Samco System.
  • On favourable sites where a high starch yield and content is sought and on less favourable sites where earliness is required.
