The studies, conducted in the period of 1972 - 1990, permit the determination of the conditions of potato production at the Bałcyny Agricultural Experimental Station, located about 10 km south-west of Ostróda. The present paper analyzes water deficiencies and excesses during the vegetation seasons, presents the ratio of precipitation to the value of current evapotranspiration, as well as the value of the mean sum of precipitation for the years 1972 - 1990 on particular days, with relation to such sums from the period of 1891 - 1960. It was found that the sums are lower than the sums of the multi-year period, especially in the first half of the year, down to 65 % at the turn of February and March. An attempt was also made at determination of the crop yield with relation to the meteorological conditions, which showed that potato crop yield is strongly affected by meteorological elements characterizing the winter preceding potato cultivation.
