The threat of climate change and its negative consequences is currently a very serious and immediate problem. Undoubtedly, the most striking manifestation of climate change is global warming, both on land and in the oceans. Increasing the average air temperature adversely affects natural ecosystems, which find it very difficult to adapt to this change. Significant consequence of climate change is also the fundamental impact on water resources. In this work we focused on the influence of climatic conditions on the dynamics of walnut tree (Juglans regia L.) in July (2019-2021), when the influence of lack of precipitation on the walnut growth are most critical. We compared dendrometric changes to air temperature and precipitation. For this measurement were used Dendrometers DD-S from Ecomatic at two groups of walnut trees – irrigated and non-irrigated trees. From the results, it is found a significant decrease in precipitation compared to the climate normal, most marked in 2021. A significant difference between irrigated and non-irrigated walnuts is seen in 2019 (3.2 mm) and in 2020 (2.4 mm). In 2021, the difference is only 0.85 mm, which could be due to insufficient irrigation, lack of precipitation, and the quantity of fruit. The impact of climate change and its greatest impact – drought, can be observed throughout the period under review. This research can serve as a basis for drought assessment and will be further developed.
