Summary Summary
This
report provides the preliminary results of 2007 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 26 260 kg and the total production is
estimated at 537 000 tonnes. The corresponding
figures for potatoes for processing of starch are 31 350 kg and 253 000
tonnes, respectively. The results for 2007 were based on a survey with a sample of 1 118
holdings for table potatoes and a sample of 185 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
tonnes. 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. 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 on to getting information directly from 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.
Starting 2006 the farmers
can use internet as a tool for data delivery concerning potato production to
Statistics Sweden. List of tables
