Climate change represents one of the major environmental problems of our time (IPCC, 2021), significantly affecting plant water regimes and agricultural production. Increased temperatures, prolonged droughts, and unpredictable rainfall patterns lead to reduced soil water availability (Allen et al., 1998), increasing the urgency for efficient and precise irrigation management. As traditional methods based on soil moisture or empirical models become less effective under variable climatic conditions (Jones, 2004), th...

In our study, we used the measurement of water potential using a pressure chamber, and we compared the collected data with the data from the Nove Zamky meteorological station for the period 21.6.2023 - 22.8.2023. The aim of the work was to compare the data collected using water potential measurements from two locations in the Nove Zamky area with the corresponding meteorological data collected from the meteorological station also located in Nove Zamky. After data collection, we then determined whether the technolo...

Climate change is a very serious threat, and its consequences affect many different aspects of our lives. In Slovakia, we will also have to get used to the faster onset of warm and dry weather in the spring. The year, from a temperature point of view, ended as the 2nd warmest since 1931. Statistically very significant (annual) deviations occurred in the entire territory of Slovakia, so we characterize it in terms of temperature as strongly to extremely above normal. We monitored the influence of climatic condition...

Pervasive environmental stressors, particularly water deficits, have a major impact on plant production, diverting necessary energy away from growth and development to mitigate stress effects. This study addresses the impact of several water regimes (irrigated and non-irrigated) on royal walnut individuals (Juglans regia L.) in an orchard in western Slovakia. Our analysis focused on sap flow measurements using the stem heat balancing method from July 13 to September 21, 2021. In the midday hours, the sap flow rate...

One of the main lines of research on the impact of climate change is the study of drought and its effects on agricultural production. The aim of this study is to determine the key parameter of plant expression in relation to water stress and soil hydrophysical properties, thereby more accurately determining the need for real-time soil profile water enhancement. The research was conducted from 2019 to 2021 at the Nove Zamky experimental site, with research on royal walnut (Juglans regia L.) During the study, we clo...

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 a...
