Abstract
The present work was carried out during two successive seasons of 2007 / 2008 and 2008 / 2009 to investigate the impact of the water stress treatments (50, 75 and 100 % field capacity FC) and foliar spray of Humic acid (HA) treatments (control, without HA and with 1% HA) on plant height, leaves dry weight and essential oil percentage and components of Majorana hortensis plants. The results can be summarized as follows: -
1- Irrigation plants with 100 % FC (control) were effective in raising the productivity of plant height, leaves dry weight and essential oil percentage and constituents.
2- Spraying plants with humic acid 1% was effective in raising the productivity of plant height, leaves dry weight and essential oil percentage and constituents.
3- The interaction between these treatments gave the best results.
4- Concerning the essential oil constituents, terpinene-4-ol was the major compound (68.24 %) resulted from 100 % FC + 1 % humic acid.
