Summary

This report provides the preliminary results of 2005 for the yield per hectare and total production of potatoes. The results are presented for counties, production areas and for the whole country.

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 27 930 kg and the total production is estimated at 618 000 tons. The corresponding figures for potatoes for processing of starch are 38 630 kg and 324 000 tons, respectively.

The results for 2005 were based on a mail survey with a sample of 1 240 holdings for table potatoes and a sample of 186 holdings for potatoes for processing starch.

The tables show the number of observations, the total and reduced yields per hectare in kg and total production in metric tons. Standard errors are also pre­sented. Unharvested areas are shown in a separate table. As for the reduced yield, the yield per hectare is reduced for small, blighted and green potatoes etc. 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.

When calculating the yields unharvested areas is taken into account, which lower the yield per hectare and owing to that also lower the production. The unharvested areas vary between years depending on the conditions during the growing season. The calculation of total production is based on the reduced yields and areas based on preliminary statistics from the administrative database for agricultural subsidies, DAWA.

The weather was wet and chilly in early growing season. The rainfall was excessive in some parts in the beginning of June. Other parts of Sweden had problems with dry conditions in July. The harvesting season had a very favorable weather giving less unharvested areas than normal.

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. At the same time methodological changes were also made. Due to the changes all comparisons between years before 1999 should be made with great caution.
