Abstract

This experiment was carried out to study the effect of bio fertilizers, active dry yeast and garlic extract on growth characteristics, essential oil determination and chemical composition of marjoram (Majorana hortensis L.) at private farm, Seif El Din Village, Zarqa City, Damietta Governorate, during 2012 and 2013 seasons.  The experiment was set up using a split-plot design with 3 replications. The main-plot included the three biofertilizers (0.0, Biogene and Biogene plus Phosphorene), whereas, the sub-plots were devoted for active dry yeast and Allium sativum extract. The final statistical analysis indicated that the highest values of herb (fresh and dry), essential oil percentage and oil content / plant, as well as the chemical constituents of  Majorana hortensis plant were produced when Biogene plus Phosphorene were combined with active dry Allium sativum or garlic extract treatments.
