Effect of Calcium Foliar Spray Technique on Mechanical Properties of Strawberries.

The calcium fertilization of strawberry plants ( × ) was evaluated using two types of nozzles, with two liquid pressure levels and two driving speeds. The calcium content of the leaves and fruit were analyzed via flame photometry. Higher leaf calcium content was found in plots sprayed with standard nozzles, while higher fruit calcium content was observed for those sprayed with air induction nozzles.
