P7647
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.
- 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.

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.
