Effect of Foliar Application with Aloe Leaf Extract (ALE) on Vegetative Growth, Oil percentage and Anatomical leaf Structure of Sage (Salvia officinalis L.) Plant under Sand soil Conditions

Abstract

The present study was carried out at the Experimental Farm, Horticulture Department, Faculty of Agriculture, Suez Canal University in two successive seasons (2012 & 2013). The aim of this work was to study the effect of aloe leaf extract (ALE) at 0.0, 10, 20 and 40 ml/L on vegetative growth, yield, essential oil percentage and leaf anatomical structure of sage plants (Salvia officinalis L.) under sandy soil condition. Aloe leaf extract (ALE) especially at highest concentration (40 ml/L) significantly increased the plant height, number of leaves, number of branches, yield and essential oil percentage as well as enhancement the leaf anatomical structure. The obtained results led to recommended producing higher yield and essential oil percentage grown in sandy soil using Aloe leaf extract.
