The present paper covers the 1990-1999 research into potato yielding and crop structure under natural conditions in the Świętokrzyskie Province. The average potato yield amounted to 15.2 t.ha^-1 and was similar to the national average. The tuber yield increased with enhanced natural conditions, soil in specific. Low yields were recorded in the communes whose natural conditions were slightly favourable or unfavourable. An average share of potato in the total crop structure on arable land was 17.5% and was 6.34% higher, as compared to the national average. The natural conditions more favourable to the agricultural production decreased the total potato plantation area; potato plantation area was most considerable in the communes of low soil quality, in the north of the province which, when maintaining the present system of set-aside in the EU, could expect subsidies.
