Effect of water stress on blueberry cultivation in pots
RDI is applied in countries in arid climates as it saves water more than in humid or temperate climates. Water deficit beyond the allowed limit will have negative consequences which are reflected in the development and ripening of fruits. In this paper, we investigated the effect of water stress caused by regulated deficit irrigation (RDI) on highbush blueberry Bluegold cultivated in pots. Our study was conducted in Kosovo during 2017 in a two-year old blueberry, using a nested experimental design. Spacing between rows was 2 m apart within rows spacing was 0.60 m. The aim was to assess the different level of irrigation on productive indices. Three levels of irrigation were applied, four irrigation drippers; three drippers; and two irrigation drippers. For each treatment we used 10 trees in pots (volume 20 L). Based on two-way analysis of variance, we found significant changes in: fruit weight, total yield and length of fruit while, changes were not significant for number of fruit and diameter of fruit. For all indices, the lowest values were found in treatment with two irrigation drippers so in our climatic conditions blueberry cultivation in pots cannot be performed with less water or without irrigation. Considering the young age of highbush and long-term consequences of water stress the experiment will be continued.
