The Maize Variety Selection Guide

Maize variety choice simplified Independent data from BSPB/NIAB maize trials Getting maize variety choice wrong can be costly in terms of missed opportunity to produce the maximum feed energy from the crop. The LG Variety Selection Guide aims to make it easier for you to interpret the valuable independent data available to help you make the correct variety choice. This guide uses the Descriptive List data which is created from independent trials jointly carried out by NIAB and the British Society of Plant Breeders (BSPB). Varieties usually complete five years of testing, at up to nine...

What do you want from your maize? GO TO Maximum fresh crop yield for biogas MAIZE FOR ANAEROBIC DIGESTION High yielding crops that maximise yield per hectare, typically later maturing varieties suitable for high potential sites. MAIZE FOR LESS FAVOURABLE SITES Early maturing crops that reduce the risk of a late harvest, providing a secure performance from a limited area of maize grown. MAIZE FOR FAVOURABLE SITES Crops that offer improved feeding efficiency that reduce purchased-in feed costs. MAIZE FOR CRIMPING OR UNDER PLASTIC Crops that can utilise plastic cover to advance maturity in...

Relative Dry Matter Yield Maize for Anaerobic Digestion - BSPB/NIAB 2018 List The 'Maize for Anaerobic Digestion List' is available to provide anaerobic digestion (AD) plant operators and growers with independent data to use when selecting varieties to maximise biogas (methane) production. This List has been compiled from over five years of independent BSPB/NIAB trial data and recognises that the selection criteria for anaerobic digesters are different from those for livestock feeding. Further information for Less Favourable sites can be found at www.lgseeds.co.uk/maize GATSBY • BONNIE Mean...

Maize variety selection for AD production Maize can be successfully grown in most areas of the UK, but it is important to choose varieties suited to the growing conditions of your farm and can achieve a dry matter content of 30-32%. As large areas of maize are needed to feed an AD plant, a range of varieties with different maturities should be sown. This enables harvesting before wet weather sets in and helps to avoid soil structure damage. Recommended LG maize varieties The extensive UK-based LG research programme has tested potential new varieties against current commercial ones at trial...

Varieties are ranked by relative starch yield to easily evaluate performance for this characteristic. Starch % at harvest Varieties with a high starch content are especially important in rations with a lower percentage of maize fed (<50%). Maize starch balances the rapidly available energy and higher protein levels found in the...
