lowest (\(p\leq 0.05\)) content of this element was determined in conventional raspberries harvested in 2021. Lithium was statistically present at the highest concentration (\(p\leq 0.05\)) in conventional raspberries from the 2020 harvest, and the lowest significant content in conventional raspberry as well, compared to the other samples analysed, where the results were comparable (\(p>0.05\)). The highest statistically significant (\(p\leq 0.05\)) beryllium concentration, compared to other samples, was found in wild-growing raspberries, while the lowest was in the conventional raspberries harvested in 2021. As for calcium, numerous authors have identified its higher levels [25; 28; 32]. Calcium levels given by [PERSON], et al. [27], amounting to 100 mg 100 g\({}^{-1}\) DW, were significantly lower than those determined in this study. The iron content, reported by [PERSON], et al. [28], corresponded to our results obtained for conventional and wild-growing raspberries from the first year of the experiment (3.84 mg 100 g\({}^{-1}\) DW). [PERSON], et al. [33] in his study on the organic and conventional raspberry cultivar Willamette, found lower iron content compared to our results.
