Harvest Results – Winter Barley (30-7-18)

Harvest results continue to show above-average winter barley yields

Harvest Results from 12 AHDB Recommended Lists (RL) winter barley trials sites – Cambridgeshire, Cheshire, Dorset, East Yorkshire, Fife, Glamorgan, Hampshire, Lincolnshire, North Yorkshire, Scottish Borders, Suffolk and Warwickshire – have been published to date (30 July), reports AHDB.

The average treated yield of control varieties (10.34t/ha) is currently ahead of the five-year average (9.9t/ha).

Information on untreated yields from six sites (Cambridgeshire, Dorset, Fife, Glamorgan, Lincolnshire and Scottish Borders) has also been published.

The average untreated yield of control varieties (7.93t/ha) is similar to the five-year average (7.74t/ha).

Differences in yield are often driven by crop establishment and rooting over the winter and the moisture retention capability of the soils. Despite the weather extremes across the UK this season, early trial results show no significant differences in yields compared to previous seasons.

Regional information on weather patterns can be found on the new AHDB WeatherHub site: cereals.ahdb.org.uk/weatherhub

2018 averages

Yields are represented as a percentage of the control varieties. In 2018, the control varieties comprise two malting varieties, SY Venture and Talisman, the six-row hybrid variety Bazooka, the six-row conventional variety Funky and the two-row feed variety KWS Glacier. The average of the yields from these varieties is represented as 100%. The current 2018 values only show yields based on one season from 12 sites.

In 2018, the six-row hybrid feed varieties Belmont (109%), Sunningdale (107%), Belfry (106%) and Bazooka (105%) are all performing well. The conventional six-row feed variety KWS Astaire (106%) is also performing well on yield.

The two-row feed varieties KWS Creswell (104%), KWS Tower (104%), KWS Orwell (104%) and KWS Infinity (102%) are showing the best yields so far in 2018.

Two-row malting varieties are judged more on their quality than outright yield. Currently, the average yields are Craft (99%), Electrum (98%), Coref (96%), SY Venture (96%) and Talisman (96%).

2014–18 (five-year) averages

The five-year average values (2014 to 2018) provide a better representation of performance across seasons.

The six-row hybrids Belmont (109%), Bazooka (108%), Belfry (107%) and Sunningdale (107%) are performing well.

The two-row feeds, KWS Orwell (103%) and Surge (102%) are performing well on yield.

Five-year average results also provide a better measure of candidate varieties. Results can only be published when varieties have completed national listing. New candidate malting varieties are not national listed at this stage, so results cannot be reported. The candidate six-row hybrid varieties are achieving good yields in the five-year average figures with SY Kingsbarn at 109% and SY Baracooda at 109%. New two-row feed varieties KWS Gimlet (104%), LG Mountain (104%), LG Flynn (104%) and Sobell (103%) are looking favourable, when compared with current popular two-row feed varieties.
