This report provides final data for the year 2008 for the yield per hectare and total production of cereal crops, dried pulses, oilseed crops, potatoes and temporary grasses. The results are presented for counties, production areas and for all of Sweden.
The tables show the number of observations, yield per hectare in kg, crop areas and total production in metric tonnes. Standard errors are given for yield per hectare and total production.
Cereals, dried pulses and oilseed crops
The total production of cereal crops for the whole country is estimated at 5 195 000 tonnes, excluding grain maize. This is three per cent more than in 2007 and four per cent more than the average for the last five years.
The total production of winter wheat is estimated at 2 004 600 tonnes. This is equivalent to 39 per cent of the total production of cereal crops.
The total production of peas is estimated at 29 100 tonnes, which is 23 per cent less than the previous year. The total production of field beans (Vicia faba L.) is estimated at 13 700 tonnes.
The 2008 harvest of rape and turnip rape is estimated at 259 400 tonnes. This is 17 per cent more than in 2007 and 30 per cent more than the average for the last five years. The total production of oil flax is estimated at 5 400 tonnes.
Since 1998, statistics on crop yields for cereals, dried pulses and oilseed crops have been based on an interview survey. For the first time in 2005, the farmers can also use Internet as a tool for data delivery to Statistics Sweden.
The sample of the 2008 survey consists of 4 377 holdings. The survey was carried out in October and November. Information was requested for total farm production in tonnes of these crops and their average moisture content. Yields per hectare at the farm level are calculated by dividing the production by the crop area of the farm. Unharvested crop areas are included and will lower the yield per hectare. Crop area statistics has been calculated from final statistics on usage of arable land. The figures on areas are mainly based on data from the Swedish administrative database for agricultural subsidies, IACS. Crop areas cut as green fodder have been excluded. Unharvested areas and areas cut as green fodder are presented in separate tables.
The results are presented for table potatoes and potatoes for processing of starch. For the whole country, the yield per hectare for table potatoes is estimated at 28 490 kg and the total production is estimated at 558 200 tonnes. The corresponding figures for potatoes for processing of starch are 40 440 kg and 295 000 tonnes, respectively.
The results for 2008 are based on a survey with a sample of 1 120 holdings for table potatoes and a sample of 177 holdings for potatoes for processing starch. The areas are based on statistics from IACS.
The tables 17 and 18 show the number of observations, the total and reduced yields per hectare in kg and total production in metric tonnes. Standard errors are also presented. Unharvested areas are shown in table 27. As for reduced yields, the yield per hectare is reduced for small, blighted and green potatoes for table potatoes. The reduction for potatoes for processing of starch is made only for blighted potatoes. These reductions are made with standard values, derived from the objective potato surveys conducted until 1998. Adjustments in the reduced yields have also been made for unharvested areas, which have lowered the yield per hectare. The unharvested area 2008 was estimated at 1.6 per cent for table potatoes and 0.2 per cent for potatoes for processing of starch.
Since 1960, Statistics Sweden has produced statistics for potatoes using an objective method based on probability sampling and physical measurements with samples taken from the fields. The method was changed 1999 to mail enquiries to a sample of farmers. Due to the changes, all comparisons with years before 1999 should be made with great caution.
The total production of temporary grasses is estimated at 4 115 700 tonnes and the yield per hectare at 4 730 kg per hectare, at 16.5 per cent moisture content. The results are presented in tables 19-22.
The results for 2008 are based on a sample of 1 000 holdings.
The survey covers only temporary grasses harvested as hay, hay-silage or silage including re-growth. It does not cover temporary grazings or re-growth from temporary grasses which are grazed.
