Cereal Quality Survey

Updated 16 Sep 2019
The Cereal Quality Survey is an annual survey looking at the key parameters of wheat and barley quality for the most recent harvest.

Overview

  • The first provisional Cereal Quality Survey results for harvest 2019/20 are now available. For the full tables of results use the link at the side of this page.  For an explanation of the results and for the wheat quality diagrams expand the sections below.

  • Early season quality of wheat is broadly in line with last year, with similar protein levels and specific weights. However, with the results only reflecting earlier havested regions samples challenged by wet weather are unlikely to be represented at this early stage.
  • For barley the first provisional estimates also highlight good quality for early harvested samples. Although it is too early to know of the functionality of this year’s crop nitrogen levels are generally lower than last season, and germination, where reported, has been good.

 

The first provisional estimates of the AHDB Cereal Quality Survey suggest that 2019/20 wheat quality is broadly in line with last year. However, with results only reflecting earlier harvested regions, samples challenged by wet weather during harvest are unlikely to be represented at this early stage.

  • Protein – Wheat protein across all nabim groups is broadly in line with the same stage last season. Across the samples surveyed so far nabim group 1 protein has averaged 13.1%, the same as this stage last year.
  • Specific weight – Specific weight of early samples are marginally down on year before levels, averaging 78.2kg/hl. However, bushel weights are still ahead of the three year average.
  • Hagberg Falling Number – The rainfall during some of the later harvested samples is not necessarily reflected in early results. Samples of nabim group 1 wheat have averaged 343s, with a range of 239s to 426s. Anecdotally, lower falling numbers have been heard and this is something we will monitor through the course of the survey.
  • Early signs of lower HFNs as the harvest moves north can be seen in samples for the midlands, where HFN averages 304s, compared with 347s at the same point last season.

Samples – 4,284

For barley the first provisional estimates also highlight good quality for early harvested samples. Although it is too early to know of the functionality of this year’s crop nitrogen levels are generally lower than last season, and germination, where reported, has been good.

  • Nitrogen – Nitrogen levels for those samples surveyed so far have generally been lower than last season. This is especially true of the spring barley results included so far with the average nitrogen reported at 1.65%, compared with 1.73% last season.
  • Specific weights – As with wheat, specific weight of barley has generally been lower so far this season.
  • Screenings – Despite smaller grain sizes, screenings have so far been reported as improved on last season, aiding the usability of this season’s crop. Across winter and spring barley the proportion passing through a 2.25mm sieve is down 1.1 percentage points, at 2.1%. Meanwhile, the proportion retain by a 2.5mm sieve is up 3.4 percentage points, at 92.3%.

Cereal Quality Calculator

This clever tool lets you see the relationship between the three markers for wheat quality – Hagberg falling number, specific weight and protein content. You can explore the data by selecting different groups, varieties or areas, as well as changing the specified ranges of the quality markers.



Additional information

The calculator shows three overlapping circles with a number in each section. Each number relates to the percentage of the overall sample that falls within the range of each quality marker. As a default, it is set to show the current year's results for nabim group one. For further information please refer to our Cereals Quality Calculator guide below.
