Bumper harvests dominated this season’s Adas-sponsored yield competition with Lincolnshire Wolds grower Tim Lamyman winning for the second year in a row.

With record average UK wheat yields and the world wheat yield record broken twice last summer, Mr Lamyman won the Yield Enhancement Network (YEN) with a crop of 16.50t/ha.

Mr Lamyman, who farms at Worlaby just south of Louth, saw his crop of Reflection wheat break the world record and also win the best field yield in the YEN competition.

The best potential yield award went to Norfolk grower Andrew Hunt who grew a 11.38t/ha crop of hybrid rye, at a calculated 81% of its potential 14.10t/ha yield.

This crop was grown on Great Melton Farms, just west of Norwich, on stony drought-prone soil.

In the trials sector, Ben Giles at Bayer CropScience, won the highest overall yield category with a crop of Skyfall reaching 15.9t/ha at a trial near Duxford, Oxfordshire.

The highest potential trial yield came from Bob Bulmer at Hutchinsons where a crop of Evolution yielded 14.02t/ha at Ludlow in Shropshire, some 79% for its 17.6t/ha potential.

Mr Lamyman broke the world wheat record with his yield of 16.50t/ha in late August, only for Northumberland grower Rod Smith, who did not enter the YEN competition, to produce a crop of 16.52t/ha.

This reflected a season when average winter wheat yields rose 2.8% to a record 8.8t/ha from 2014’s 8.6t/ha, according to Defra estimates.
