Olive seedlings growth as affected by humic and amino acids, macro and trace elements applications

Abstract

Spraying Chemlali olive seedlings with humic and amino acids, macro and trace elements, as a single or in different were evaluated during two successive seasons 2008 and 2009. Each treatment was sprayed three times (March, July and September). Shoot and root characteristics also leaf macro and trace elements were discussed. The obtained results indicated that treatment of (Humic acid +amino acids+ macro elements+ trace elements) was the most effective one compared with the other treatment since this treatments gave the best results concerning plant height, brunch numbers, leaf numbers, also it increased plant diameter and leaves area comparing with control. On the other hand, this treatment raised root length and root weight than the control plant.
