Largest regional fluctuations in the grain protein content
Based on the quality analysis of the samples from the grain harvest, three quarters of the spring wheat is suitable for bread (hectolitre weight ≥78kg, protein ≥11.5 % and falling number ≥180). As the hectolitre weight and falling number are high, the protein content is the limiting factor. If the protein requirement is increased to 12 per cent, the percentage of wheat suitable for bread grain decreases to about 60 per cent. The protein has been 11.5 % in only half the samples from Finland Proper. In Uusimaa, Satakunta and Kymenlaakso the percentage has been over 80 per cent. The average falling numbers are still very high for wheat. In Uusimaa the average, 320, is somewhat lower than in Finland Proper (331) and Satakunta (347).
The hectolitre weight and the falling number have been high also for autumn wheat. The protein content is somewhat lower than for the spring wheat, averaging 11.9 %. Also the Zeleny number is low for the autumn wheat at 33.
The protein content for the malting barley varieties is on average 12.3 per cent. For samples designated for malting, the corresponding number is 12.0 %. The content is somewhat lower in Finland Proper and in the area of the Uusimaa Swedish language Rural Advisory Centre, where the average is 11.4 %. In Uusimaa (12.3 %) and Häme (12.4 %) the averages in the samples designated for malting are higher than the average for the whole country. For grading of malting barley, >2.5 mm grains, there are no large regional fluctuations.
The protein content in barley has been quite even regionally. The exceptions are Satakunta (11.0 %) and North Savo (11.3 %), where the average levels have been below the level in the whole country (11.9 %). The highest hectolitre weights have been in Finland Proper (70.0 kg) and Satakunta (69.1 kg). Of the samples from these regions, over 90 per cent had a hectolitre weight of over 64 kilograms. Out of the samples in all of the country, 85 per cent exceeded the said limit. The lowest average hectolitre weights have been in Central Finland (65.8 kg) and Central Ostrobothnia (66.0 kg).
The average hectolitre weight of oats in the whole country is 56.1 kilograms. The highest averages per Rural Advisory Centre are in Häme (57.9 kg), Satakunta (57.8 kg) and Oulu (57.3 kg). In all of these, over 90 per cent of the samples have been over 55 kilograms, while the percentage in the whole country is about 70 per cent. The lowest averages are in Pirkanmaa (54.3 kg) and North Karelia (54.0 kg). As to grain size, the lowest percentage of less than 2.0 mm grains has been in North Savo (3.9 %), Häme (7.3 %) and Pirkanmaa (8.7 %). The percentage of small grains has been the highest in North Karelia, on average as much as 23.4 per cent.
