| Abstract:
This study was undertaken to elucidate the relationship between late ripening and the nutrition of the olive in five locations in the Marmara region (Orhangazi, Gemlik, Mudanya and Erdek) where olives are grown widely. Leaf, fruit and soil samples taken for successive years to cover both productive and non-productive years were obtained from 30 different olive orchards producing “Gemlik” variety. Chemical analyses of fruit and leaves were made and the maturation index of olives was determined. It was found that significant and positive correlations exist (P< 0.01) between; the K content of the leaves and the maturity index; the K/Ca+Mg ratio of the leaves and the maturity index; the total nutritional level of the leaves and the maturity index; the K content and the P content of the fruit flesh and the maturity index; the K/Ca+Mg ratio of the fruit flesh and the maturity index. Significant and negative correlation exist (P<0.01) between; the N/K ratio of the leaf and the maturity index; the N/K ratio of the fruit flesh and the maturity index. It is observed that the K content, K/Ca+Mg rate and the total nutritional level of the leaves increased with maturity index in contrast to N/K. The N/K rate, on the contrary, decreased in the fruit flesh while the maturity index increased. | |
