Ecology and Environmental Protection
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 measurements reached their highest daily levels. The irrigated variety had the maximum flow rate of 287.99 g.h-1. The Highest sap flow rate in the non-irrigated variant was 148.33 g.h-1. In the irrigated variant, the soil water content reached 41.61 %. Non-irrigated variant reached only 20.47 % of soil water content. The obtained data showed us the differences between irrigated and non-irrigated variants. The imperative for continued re-search emerges as additional data are needed for the optimization of irrigation strategies.
