Three AHDB Recommended Lists (RL) spring barley trials are included in the Harvest Results released today (2 October 2017).
The additional trial results, gathered from sites in Shropshire, Fife and the Scottish Borders, put the average yield of the control varieties at 7.43t/ha across the 12 trials validated to date, which is less than the five-year average of 7.76t/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%.
2017 results
The 2017 values show yields based on one season from the 12 sites validated to date.
Laureate (fully approved for brewing and distilling), RGT Planet (fully approved for brewing) and Sienna (fully approved for malt distilling), have achieved a yield of 105%. Chanson (provisionally approved for brewing), Dioptric and the feed variety, Scholar have achieved a yield of 104%.
Using the five-year average
The five-year (2013 to 2017) average is a better measure of variety performance over the past few seasons.
Over the longer term, RGT Planet (105%), Laureate (104%), Chanson (104%), LG Opera (104%) and 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.
Candidate varieties
Results on three potential malting candidate varieties – RGT Asteroid, LG Diablo and LG Tomahawk – are also reported on this week. Based on the five-year averages, LG Diablo currently has a yield of 107%, LG Tomahawk 106% and RGT Asteroid 103%.
