Winter barley yields continue to be higher than average, according to new HGCA harvest trials in Perthshire and Essex.

This year’s average yield was now 10.01t/ha, compared to the five-year average of 8.99t/ha, said recommended list manager, Simon Oxley.

“The six-row hybrid feed variety Volume continues to top the yield table with a yield of 106% of the control varieties, and 107% in the five-year average,” he said.

“The six-row conventional variety KWS Meridian has also performed well, with a yield of 105% which compares favourably with the five-year average yield of 103%.”

The two-row feed varieties California and KWS Glacier had yielded 102%, with KWS Tower at 101%.

Brewing varieties SY Venture and Talisman had five-year average yields of 98% and 99%, respectively, added Dr Oxley. 

“The candidate feed varieties continue to perform well, and their current five-year average yields are Daxor (six-row conventional 106%), KWS Infinity (two-row feed 104%) and Perseus (two-row feed 103%).”

Oilseed rape trial results this week were from Essex, Suffolk and Lincolnshire, bringing the average gross output from HGCA results to 5.44t/ha – 0.1t/ha above the four-year average.

“Incentive has a gross output of 109% and remains a strong performer in 2014 trials,” said Dr Oxley. “Looking at the four-year average figures, Incentive and Charger both have a gross output of 106%.”

There were some impressive yields from some of the new candidates, he added.

“The High oleic low linolenic (HOLL) variety V316 OL has a gross output of 115% in 2014 trials, and the high yield is also reflected in the four-year average.

“Campus, Popular, SY Harnas, Picto and Arazzo are also strong yielding varieties from the four-year gross output figures.”

The first yields from the north region will be reported next week.
