This report provides preliminary results for the year 2003 for the yield per hectare and total production of cereal crops, peas and oilseed crops. The results are presented for all of Sweden.
Cereals, peas and oilseed crops
Total production of cereal crops for the whole country is estimated at 5.32 million tons. This is almost equivalent to the average for the previous five years. A decline in the yields per hectare of winter sown cereals was to some extent compensated for by increasing crop areas.
The total production of winter wheat is estimated at 2.0 million tons. This is equivalent to about 37 per cent of the total production of cereal crops. Areas under cultivation for winter wheat fluctuate very much due to weather conditions in the autumn of the previous year. Favourable weather in the autumn 2002 offered god opportunities for sowing winter crops. However, dry conditions persisted too long, and caused a negative impact on the crop development.
Total production of peas is estimated at 81 100 tons, which does not differ very much from the average for the previous five years.
The 2003 harvest of rape and turnip rape is estimated at about 132 000 tons. Compared to the previous year, this is a reduction of 17 per cent. This drop is due to both lower yields per hectare of spring rape and a reduced cultivation of rape and turnip rape. The total production of oil flax is estimated at 6 600 tons.
Since 1998, statistics on crop yields for cereals, peas and oilseed crops have been based entirely on an interview survey. The sample of the survey of 2003 consists of 4 350 survey units. The selected farms are a random sample from throughout the country. These preliminary results are based on a subsample of 1 087 survey units. These units receive priority in the survey and in the subsequent data processing at Statistics Sweden. The survey was carried out in October and November. Information was requested for total farm production in tons of these crops and their average moisture content. Yields per hectare at the farm level are calculated by dividing the total production by the crop areas of the farm. The total production was calculated from data on yield per hectare; area statistics were calculated from preliminary data on usage of arable land in 2003. These area data are based on figures from the administrative database for agricultural subsidies, IACS. Crop areas cut as green fodder have been excluded.
The tables show the number of observations, yield per hectare in kg, total production in metric tons and crop areas. Standard errors are given for the yield per hectare and total production.
