THE IMPACT OF SOILWATER STORAGE ON THE RADIAL CHANGES OF THE ROYAL WALNUT (JUGLANS REGIA L.)
Abstract
Climatic conditions have significantly changed over the last decades. In the middle latitude, the annual precipitation total does not change significantly, but precipitation is unevenly distributed throughout the year. The aim of the research is to investigate the effects of climatic conditions on the dendrological changes of the Royal walnut (Juglans Regia L. var. Chandler) in the period from July to November 2020 in the conditions of the middle latitude of southern Slovakia. This area is characterized by intensive agricultural production. We measured radial branch changes using DD-S dendrometers (Ecomatik Inc.). In the research, we used the possibility of applying regular irrigation doses to a part of the monitored trees. An irrigation dose of 30 mm was applied in the irrigated part depending on the meteorological conditions. We compared the measured data with the soil water storage in the depth of 20 cm of soil. The results show that the radial diameter of the branches in the irrigated variant increased continuously during the research period (more than 5 mm) and slowed down in the autumn period (beginning of October). On the other hand, the non-irrigated variant stagnated (enlarges less than 0.5 mm)during the whole research period. Minimal growth was detected in October, whichwas significantly altered and increased was caused by significantly higher totalprecipitation. The conclusions of the research can be used to design the amount andtiming of irrigation, which will be increasingly needed in our conditions to achieveoptimal agricultural production.
