P7034

P7034 is a very early maturity hybrid intended for favourable sites and warmer less favourable sites. Pioneer classifies P7034 as an ‘M3 ’ hybrid because in Pioneer research and PACTS testing it has produced starch of a very high rumen degradability. The high rumen degradability of P7034 is associated with its dent like starch texture.

P7034 has been extensively tested in PACTS trials on 33 favourable open locations and 39 less favourable open locations over the last four years. It has been tested under film over 29 locations. P7034 has flowered early and produced silage with a high starch content.

The highly degradable starch type of P7034 can lead to significantly faster starch degradation in the rumen compared to more flint grain textured hybrids. This is especially the case soon after ensiling and before silage acids have had the effect of degrading the protective protein that surrounds the starch in more flint type hybrids.

Where possible crops of P7034 should be clamped last and fed first. This ensiling sequence may aid the feeding transition from old to new crop maize silage, and it fully exploits the starch degradability characteristic of P7034. P7034 is a good partner hybrid to Pioneer hybrids such as P7179, P7326 and P7381 which have broadly similar maturity but more typical levels of rumen degradable starch.
