Abstract
In the experiment, the ‘Duke’ blueberry cultivar was used, which was grown in an unheated foil tunnel in peat substrate to eliminate the influence of rainfall on the course of the experiment.
Two-year-old bushes in three-liter containers were obtained from a specialized farm.
In the first ten days of April, they were transplanted into ten-liter pots filled with peat substrate with a pH of 4.25. Ground bumblebees pollinated the blueberries.
Fertilization in both experimental combinations was the same.
Half of the plants were watered using the ISS Hydreset system, while the other half served as a control and were watered from the same source without the use of this system.
The same irrigation doses and terms were used.
Water treated with ISS Hydreset is characterized by higher oxygen saturation and lower viscosity.
This is probably why it is more easily taken and transported up by plants, which have to use less energy for its transport.
As a summary, it can be stated that the use of the ISS Hydreset system for blueberry irrigation had a positive effect on the yield, contributing to a significant increase in the total yield, average fruit weight, and polyphenol content in berries.
The total yield increased by 11.3%. These fruits were also larger, which is what the market is looking for.
The content of ash, total sugars, and simple sugars in fruits was higher in combination with the use of an ISS Hydreset irrigation system, but the differences were not statistically confirmed.
The remaining quality features were not significantly modified by the type of watering system used for irrigation.
