Maize Descriptive list simplifies variety choice
The NIAB 2011 Forage Maize Descriptive List has a new look following changes aimed at simplifying the variety choice process for growers.
The most significant change is the amalgamation of the Medium Early List and the Favourable List followed by a more vigorous selection of first choice forage maize varieties, explains NIAB’s Herbage and Forage specialist Don Pendergrast.
"The modifications have been made in response to feedback from growers asking for fewer lists and a smaller number of first choice varieties. But they still wanted a good range of variety choice and lists that represent key UK growing conditions," says Mr Pendergrast.
Growers now have two lists of first choice varieties to consider:
• Marginal - for situations where reaching a good percentage dry matter is key; and
• Favourable - capable of growing a range of maturity classes, but key is the ability to drill a following crop and/or the percentage of maize in the ration.
With only one Favourable List variety selection will be more straightforward. In the past growers had to compare varieties, and their traits, across two different lists.
This year selection of first choice forage maize varieties has been more vigorous than ever; falling to 35 varieties on the Less Favourable List and 40 on the Favourable List. This is a drop of 40% compared to 2008 when there were 58 first choice varieties on the Less Favourable List.
The 2011 NIAB Descriptive List includes seven new varieties for use in favourable and less favourable growing locations, and two new varieties for favourable locations where the best maize yields are available.
"Of particular note for those in a favourable location looking for big energy yields are NK Baleric and Atrium. Both raise the standard in terms of energy yield (NK Baleric) and energy density (Atrium). For growers in less favourable conditions, or situations requiring early harvest, Kougar offers an unparalleled yield, whilst Kentaurus offers a great balance of yield and quality, outstripping anything of similar maturity," advises Mr Pendergrast.
