Abstract
In this study, the effects of different irrigation levels (IR125, IR100, IR75 and IR50) and bio-activator application on micronutrient (Fe, Cu, Mn and Zn) concentrations of fruits and leaves of cultivar Rubygem were investigated during the active harvest period of 2015-2016. As a result of the study, which carried out in Çukurova University trial area, it was determined that different irrigation levels caused significant differences in all micronutrient element concentrations examined in leaves, although it caused significant changes only in Fe and Zn concentrations in fruits. IR50 application was found to be in the highest importance group in leaf Fe, fruit Fe and Zn concentrations, while IR75 application was found to be in the same importance group with IR100 for Zn, Cu and Mn concentrations according to both fruit and leaf analysis results. In the experiment, it was determined that bio-activator applications significantly increased Zn, Cu and Fe concentrations of both leaves and fruits. Therefore, it is thought that bio-activator application can be an important strategy for strawberry cultivation and at the same time, 25% restricted irrigation can be considered as an alternative method to full irrigation in water shortage areas.
