Growth and nutrient status of olive plants as influenced by foliar potassium applications

Olive (Olea europaea L.) plants were sprayed (one, two or three times) with nutrient solutions containing KCl, KNO3 and K2SO4 with the same amount of K (0, 1, 2 and 3% w/v). The weight of the plants was unaffected by salt type, number of sprays or K concentration of salts, whereas the dry matter per...

The weight of the plants was unaffected by salt type, number of sprays or K concentration of salts, whereas the dry matter percentage was significantly increased in the plants treated with K2SO4. Furthermore, the application of K2SO4 led to a significantly higher N concentration in leaves than that of KCl. K-salts increased K concentration in plants in the following order: KCl> KNO3> K2SO4 and three foliar applications were significantly more efficient than one. Moreover, irrespective of plant part, K spray application frequency significantly affected Fe and Zn concentrations in the plants studied. Finally, although KCl increased Cl concentrations more than KNO3 and K2SO4, the former fertilizer was the most efficient to improve the K status of the olive cv.
