Growing Maize in the uk

In terms of the economics of the crop, for varieties grown for anaerobic digesters, yield should be expected to be 45 to 60 tonnes per hectare and contracts to supply digesters should be worth around £35 to £40 per tonne.

Over the past few years the area of maize in the UK has seen a steady increase. The total area in 2012 was thought to be about 160 kha. The area increase is expected to continue in 2013 as spring cropping will be more in demand. However with maize being grown widely across Europe and plenty of choice in terms of varieties, maize seed availability in 2013 is also not expected to be a problem.

Varieties

Selecting the correct variety is key and is dependent on the intended end use of the product. For anaerobic digestion varieties such as Fabregas, Ronaldinio and Barros should be used to ensure maximum yield as the main consideration, whereas starch content should be the main driver when growing as a forage crop. Varieties such as Kentaurus, Ambrosini and Kontender are more suitable for forage.

Drilling Considerations

Maize is generally sown mid-April time and harvesting is carried out towards the end of September or into October. When drilling be aware of soil temperatures. For light soils the temperature must be 8 degrees Celsius for 3-4 days and for heavier soils 10 degrees Celsius for 3 to 4 days should be observed. This ensures the best possible establishment of the crop.
