Preliminary data from Evira and Tike on the quality of the grain yield in 2010

23.11.2010

<p>A dry summer produced a small yield of grains but also lifted protein density in all grain crops to high levels. The amount of millable wheat rose to a six-year-high of around 480 million kilograms. The falling number for wheat was the highest since 1997. At around 60 million kilograms, the yield of malting barley was smaller this year as a result of high protein density and a weak overall yield. The quality of feed grains was weakened by a low hectolitre weight and the small kernel size of oats. Of the almost-70-million-kilogram yield of rye, more than 90 per cent was suitable as bread grain.</p>

More than half of wheat suitable as bread grain
 Of autumn’s 720-million-kilogram yield of wheat, around 480 million kilograms met the quality criteria to be used in bread. The overall yield consisted of 635 million kilograms of spring-sown wheat and 88 million kilograms of autumn-sown winter wheat. The average falling number for the winter wheat yield was the highest since Finland joined the EU in 1995, and the yield of spring-sown wheat was the highest since 1997. The protein density of spring-sown wheat was also high and the hectolitre weight was good on average.

There were significant regional differences. In Uusimaa and Häme more than 85 per cent of the spring-sown wheat yield was suitable for bread, in Southern Ostrobothnia almost 70 per cent, in Southwest Finland and Pirkanmaa less than 65 per cent, and in Satakunta only around half. Low protein density was the main cause of reduced suitability, regardless of the regions’ mainly high average protein density. Thus, there were significant variations in quality within the regions, too. The choice of cultivar did not account for the variation. Unevenly distributed rainfall is presumably the most important explanatory factor.

More than 90 per cent of the 70-million-kilogram yield of rye was suitable as bread grain, whereas last year only around half the yield fulfilled the bread grain quality criteria. In Southern Finland and Satakunta the entire rye yield was suitable for bread grain, and in Southern Ostrobothnia the equivalent proportion exceeded 80 per cent.

Only a quarter of malting barley suitable for malting
Only a quarter of the malting barley yield of 60 million kilograms fulfilled the malting industry’s quality criteria when taking into account the sorting rate and the upper limit on protein density of 11.5 per cent. The greatest regional difference was between Uusimaa and Southwest Finland: In Uusimaa 35 per cent of the yield fulfilled the criteria, in Southwest Finland only 19 per cent.

The hectolitre weight of feed grain was low, oats were fine-grained
Half of the barley yield had a hectolitre weight of more than 64 kilograms, whereas a year earlier the proportion exceeded 80 per cent. Protein density was instead higher than in previous years, and starch density correspondingly lower.

The hectolitre weight of oats was the lowest in more than twenty years. More than 71 per cent of the oats yield exceeded the minimum hectolitre weight of 52 kilograms generally applied in feed production, but only 3 per cent of the yield exceeded the minimum hectolitre weight of 58 kilograms generally required of grit oats. Last year 27 per cent of the yield met the requirements for grit oats. There were significant regional differences. In addition, the kernel size of oats was the smallest since Finland joined the EU. The protein density of oats was high.

Data on the quality of the grain yield in 2010 is still of a preliminary nature at this stage. The grain yield quality table based on finalised data will be published on 24 February 2011. The table combines grain yield quantities recorded in Tike’s crop production statistics with quality control data on the 2010 grain yield from the Finnish Food Safety Authority Evira’s grain laboratory. Around 5,500 farms responded to Tike’s study, with some 400 of these farms submitting grain samples to be analysed as part of Evira’s grain quality control.
