The study was conducted as open field trial, with irrigation, with the Clery strawberry variety. The aim of the study was to investigate the effect of foliar application on berry and seaweed extract on the yield and quality of strawberry fruit (sugar, acid and anthocyanin content). The experiment was set up by random block system in 4 repetitions. The following treatments were applied to the strawberry crop: 1. control, 2. conventional NPK fertilization (10-52-10), 3. 30% reduced conventional NPK fertilization, 4. 30% reduced conventional fertilization + biostimulants. Due to arid growing conditions, NPK fertilizer was applied foliarly. Statistical analysis of the data showed significant differences between treatments in strawberry yield, and anthocyanins content. Compared to the control, the biostimulator had an effect on strawberry yield and total anthocyanin content, but not on the total soluble sugar and acid content of strawberry fruit.
