Abstract
Abstract Background This work was carried out through 2017 and 2018 seasons on tow olive cultivars (Kalmata and Manzanillo). Trees were 15 years old, grown in sandy soil, planted at 5 × 5 m apart, and irrigated with saline water through drip irrigation system. This investigation aimed to improve vegetative growth and its mineral contents of the tow olive cultivars. Trees were sprayed with calcium at 0.5% as calcium chloride (21% Ca) and chelated calcium. Results The results revealed that there were significant differences with calcium source treatment regarding vegetative growth and leaf mineral contents. Conclusions Results proved that olive trees sprayed at the end of December with 0.5% calcium as chelated calcium was the promising treatment for good vegetative growth and leaf mineral contents.
