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...

Climate change is the most pronounced in the last thirty years. In the world, but also in Slovakia, there are extreme temperatures and frequent periods of drought alternating with torrential precipitation. Neither of these two options is suitable for the country. The aim of this article was to determine the distribution of precipitation in the period 1991- 2020. Using the Mann-Kendall trend analysis, it was determined a statistically significant increase or decrease in precipitation in individual months of the yea...

It is important to gain a better understanding regarding the effect of frequent drought stress on biochemical and physiological processes in plants as well as on the plant population and community in ecosystem. One method of early detection and monitoring of water stress is by measuring the diameter changes of the stem using dendrometers. They can be used to determine not only the annual thickness growth, but also the distribution of the growth and the rate of expansion and shrinkage of the wood and bark during th...

Climate-change scenarios all around the world indicate that many areas of the globe will increase in aridity. Plants need a large amount of water and nutrients throughout their life cycle and all aspects of plant development are affected by a reduction in water content in the soil. This reduction in soil moisture leads to changes in the physical environment, which subsequently affect physiological and biochemical processes in plants. Based on sap flow measurements, it is possible to optimize irrigation. For our ex...

Agricultural production is based on responding issues related to climate change in the coming years. Frequent drought seasons lead to a decline in yield production, and negative hydrological balance is expected in the future, which will also affect water consumption for agriculture [1]. Based on sap flow measurements, it is possible to optimize irrigation. For our experiment was used the grape vines in Nitra region, on which we installed Dynagage Sap Flow Sensors with the Flow 32-1K Sap flow system, which measure ...
