The first Harvest Results from the 2018 AHDB Recommended Lists (RL) spring barley trials have been published, reports AHDB.
The initial results are from five sites that cover a wide geographic area – from the North (Angus, Perth and East Lothian), the East (Lincolnshire) and the West (Devon).
Based on these results, the average yield of the control varieties stands at 7.33t/ha, which is 0.52t/ha below the five-year average of 7.85t/ha.
The 2018 weather made it a challenging year for crops, including spring cereals in the RL trial system. The wet spring caused a delay in drilling and the hot, dry summer shortened the season. Moisture was also limiting, particularly in lighter soils.
Calculating yield results
Yields are represented as a percentage of the control varieties. In 2018, Concerto, KWS Irina, Laureate, Propino and RGT Planet are the control varieties. The yield average from these varieties is represented as 100%.
The 2018 values, to date, show yields based on one season from the five sites. LG Diablo (provisionally approved for brewing and distilling) has achieved a yield of 106%, with Laureate (fully approved for brewing and distilling), LG Tomahawk and Scholar all achieving 105%.
Using the five-year average
The five-year average is a better measure of variety performance over the past few seasons (2014–2018).
Over the longer term, LG Diablo (106%), RGT Planet (104%), LG Tomahawk (104%), Laureate (103%), Chanson (103%) and Scholar (103%) are all performing well. Propino achieved 98%.
When choosing varieties, market requirements, rather than yield, should drive variety selection.
Looking at the five-year average yields for the 2018 candidate varieties, the potential malting variety Cosmopolitan achieved 106% and SY Contour achieved 104%. The top-yielding potential feed candidates are SY Kailash (105%) and Embrace (104%).
