The influence of climatic conditions on the development of the juglans regia l. in the spring months in slovakia

Several organizations warn of the increase in temperature and the associated extreme climatic conditions for life on Earth. The aim of this article is to point out the influence of climatic conditions on the development of walnut (Juglans regia L.) in the spring months (11.5. � 18.6.) in the years 2018 � 2019, which were above-normal to temperature-normal (compared to the climatic normal 1991 � 2020) and in the years 2021 � 2022, which were below normal temperatures. The impact of the amount of precipitation was also compared. Diameter Dendrometer Small dendrometers (Ecomatik) were used for the research on irrigated and non-irrigated variants. The results showed that in 2018 and 2019, at higher temperatures and also with a short-term lack of precipitation, the increase in averages was higher. However, in the years 2021 and 2022, with the below normal temperature period in the spring and the lack of moisture, especially in the June, with additional irrigation with micro sprinklers did not help, and the increases are low for both the irrigated and non-irrigated variants. Climate change is currently present in all sectors of the economy, and such research is necessary for better adaptation of humans and plants on Earth.
