Fruit cracking is one of the important quality parameter in dried fig marketing. Two different research have beencarried out to determine the effect of nutritional status on fruit cracking of fig (Ficus carica L. cv. Sarilop) grown inhigh level boron (B) contained soils of Aydın, Turkey. In the first research, fig trees were grouped depending oncracked fruit ratio. Nutrient contents of soil, leaf and fresh fruit taken from each group were evaluated by cracked fruitratio of fig trees. In the second study, K₂SO₄, NH₄NO₃, CaCl₂, MgSO₄ and H₃BO₄ fertilizers were sprayed to the trees. Comparing with reference values of leaf and fruit, calcium (Ca) content was low but B content was high while othernutrient contents were in normal range in both experiments. Cracked fruit ratio was given positive correlationcoefficients by soil B , leaf B and peel B contents; and negative correlation by soil potassium (K), leaf Ca and peel Cacontents, soil Ca/B, leaf Ca/B, soil Ca/(K+Mg+Na) and fruit Ca/(K+Mg+Na) ratios.
