Energy Maize
First Class Mass
KWS launched a dedicated breeding program for energy maize in 2002. Since then yields per hectare have increased by some 20%.
What is the right variety for biogas production?
Variety choice for biogas production should be aimed at achieving the highest potential methane output and should take account of the following:
- Maturity
- Cost per tonne of fresh matter
- Harvest window
|
Requirements of maize: |
|
|
Cattle Feeding |
Biogas Output |
|
Minimum methane production in the rumen |
Maximum methane production |
|
Dwell time: 5 - 10 hours |
Dwell time: 50 - 100 days |
|
Maximum feed value (starch, digestibility) |
Maximum methane output (DM yield/ha) |
|
Sufficient dry matter for feed intake (30 - 35%) |
Sufficient dry matter for fermentation (27 - 31%) |
Characteristics
- Very high fresh yield potential (55 – 65 t/ha)
- Large structured hybrids with excellent standing
- Safe maturity for the majority of mainstream sites (28 – 31% DM)*
- Moderate stay green (recommended chop length 4 – 5mm)
Recommended varieties from KWS
FABREGAS – (Early – FAO 220)
Massive yields with early maturity – ideal for all areas of the UK
RONALDINIO (Mid Early – FAO 240)
Combines great yields with good maturity
FRANCISCO (Late – FAO 260)
For maximum yields and harvest spread
