In this study, examination the tendency of climate variability at Tokat Kazova with drought point of view was aimed. The possible effects of this tendency on agricultural production were discussed. The monthly, seasonal and yearly precipitations and temperatures measured at the weather station of Tokat Soil and Water Resources Research Institute during 1966 through 2006 were used. For these series, first visual trends were examined, then the Mann-Kendall test at a = 0.05 significance level was performed to determine whether the determined increases or decreases in the series are important or not. At the plain, it was determined that the trend line for the annual average precipitation data with respect to the years have not changed. However, the decreasing trend in the precipitations during winter was found important. In addition, while it is small, the overall average temperature for the years is being decreasing, the increasing and decreasing trends in maximum and minimum annual temperatures, respectively, were found important
