Description	The yield variability of potatoes over twelve years from 1980 to 2001 in a long-term fertilization experiment in Prague-Ruzyně was analysed. The regression analysis showed a positive linear relationship between yields and average temperature in April and May – the correlation coefficient (r) ranged from +0.47 to +0.78 in twenty-four treatments. A similar relation was found for the average minimum and maximum temperatures in the same months. The average temperature of thirty days before and after the date of planting improved the fit up to r = +0.86; the average r of treatments was from +0.62 to +0.78. The sum of winter precipitation (January - March) was also positively correlated with yields (r from +0.52 to +0.74) but the precipitation during growth was not. The simple combination of average temperature and winter precipitation improved the fit to an average of +0.78 (r from +0.69 to +0.86), i.e. the indicator explained up to 75 % of yield variability.
