Harvest Results are reported for five AHDB Recommended Lists spring barley trials (18 September).
Results which include sites from Devon, Yorkshire and Scotland, show an average yield of the control varieties at 8.31t/ha, which is above the five-year average of 7.87t/ha.
Calculating yield results
Yields are represented as a percentage of the control varieties. In 2017, Concerto, KWS Irina, Odyssey, Propino and RGT Planet are the control varieties. The yield average from these varieties is represented as 100%.
The 2017 values show yields based on one season from the five sites. Laureate (fully approved for brewing and distilling), RGT Planet, (fully approved for brewing) and Sienna (fully approved for malt distilling) have all achieved a yield of 105%.
Using the five-year average
The five-year average is a better measure of variety performance over the past few seasons (2013–2017).
Over the longer term, RGT Planet (105%), Laureate (104%), Chanson (104%, provisionally approved for brewing), LG Opera (104%) and the feed variety Scholar (104%) are performing well. Popular varieties Concerto and Propino achieved 94% and 100% respectively.
When choosing varieties, what the market requires should drive variety selection.
