There are now 21 spring barley harvest results from the 2015 AHDBRecommended List trials, including two new trials from Scotland, Tibbermore and Dundee, and two from Northern Ireland, Strabane and Crossnacreevy, reports AHDBCereals & Oilseeds.
Average yield of the control varieties now stands at 8.35 t/ha, 0.91t/ha above the five-year average. Spring barley appears to be mirroring the winter barley results with higher-yields recorded this year compared to the five-year average.
There is, however, a high-range of yields across sites this year. The control varieties at the site in Herefordshire achieved an impressive yield of10.40 t/ha, while a site in Perthshire averaged 6.38 t/ha.
Malting varieties are selected on the basis of quality and end-user requirements as opposed to yield alone.
Fully approved varieties for brewing and distilling include Odyssey(103%) and Concerto (97%) and fully approved brewing only varieties include KWS Irina (105%) and Propino (100%). All are yielding well.
For the varieties under test, two varieties for potential brewing and distilling include Sienna (102%) and Octavia (104%), while RGT Planet (107%),which is under test for brewing only, continues to yield well.
Feed varieties with the highest 2015 yields include Shada (106%) andScholar (105%).
When selecting varieties for next season, the five-year average values give a better representation of performance in different seasons.
Odyssey (102%), KWS Irina (106%) and Shada (106%) all show good performance, based on the five-year average, for their respective markets.
Looking at candidate varieties, the potential malting varieties, Ovation and Laureate appear to be strong performers based on their five-year average yield (107%).
