Winter wheat averaged 6.9t/ha in the Agricultural and Horticultural Development Board's (AHDB) final harvest 2026 survey, 11% below the UK five-year average and with reported yields ranging from 3.9t/ha to 11.5t/ha.

The board published its closing update this week. Winter wheat harvest is now complete across the UK, with the sample average edging up as more Scottish and northern English crops came in. The wider picture confirms a season shaped by limited rainfall from spring onwards, with national averages for wheat, spring barley and oats all falling short.

How did each crop perform?

Winter barley held close to its five-year average at 6.9t/ha. AHDB describes the crop as broadly in line with the benchmark.

Spring barley told a different story. The crop averaged 4.8t/ha, roughly 17% below the five-year figure despite an uplift from late-harvested northern crops. AHDB classes spring barley as one of the most challenged crops of the season.

Oats improved as combines moved into Scotland, closing at 4.6t/ha. That figure remains about 14% below the UK five-year average. Substantial variation between farms and regions was reported in both oats and spring barley.

Oilseed rape was the clear outlier. The crop averaged 4.0t/ha across the survey sample, approximately 19% above the five-year average. AHDB analysts describe oilseed rape as the standout performer of harvest 2026, though farm-to-farm variation remained significant even within the crop.

Why such a wide spread between farms?

AHDB lists seven factors behind the divergence: soil type and its capacity to hold moisture; drilling date; organic fertiliser use; previous cropping; variety choice; seed type; and local weather conditions.

Some growers, particularly in the north, are achieving results at or above their long-term averages. Many others are reporting substantial reductions. The 3.9–11.5t/ha wheat spread shows how sharply conditions rewarded or penalised individual fields within the same season.

The contrast between Scotland and southern England is the clearest indicator. Northern crops drilled into moisture-retentive soils survived the dry spring better than later-drilled crops on lighter land further south, where harvest raced through with disappointing yields.

How will growers manage the grain in store?

Quality of the 2026 UK grain crop is highly variable, AHDB confirms. That variability will complicate store management through the winter and into spring 2027. Blending decisions, drying schedules and marketing plans will all depend on regional quality data still being collated.

Harvest progress slowed as work moved into wetter northern regions and Scotland. Crops coming off those combines carried higher moisture levels, though yields also improved in those areas. Drying capacity will be a key constraint for growers finishing harvest under Scottish skies.

England and Wales saw rapid, straightforward harvests with disappointing yields. Northern England and Scotland delivered better-tonnage crops but required more drying attention and time.

What should farmers watch next?

The AHDB post-harvest grain quality summary is the next key release. Growers should track regional store reports as combines finish in the last Scottish areas and as maltsters, millers and oilseed crushers publish intake specifications for the 2026 crop.

Forward planning for harvest 2027 starts now. Winter wheat and winter barley drilling decisions will hinge on soil moisture reserves built up over winter 2026/27, a variable AHDB will begin monitoring in its early-season surveys.
