Abstract: A filed experiments was carried out during two successive seasonsof 2005/2006 and 2006/2007 to study the effect of applying biofertilizer(active dry yeast) as foliar spray at rates 0, 1, 2 and 3 g/L, alone or withthe recommended doses of "NPK" as mineral fertilizers at the rates of(400 Kg/fed ammonium sulphate + 200 Kg/ fed calcium superphosphate+ 100kg/fed. potassium sulphate) or three forms of organicmanure (farmyard ''FYM''; poultry ''PM'' and sheep manures "SM") at arate 25 m3/fed. on growth and chemical constituents of marjoram(Origanum majorana L.,) plants which grown by terminal cuttings.The obtained results indicated that growth parameters (i.e., plantheight, number of branch, fresh weight of herb, yield of herb dried airweight /plant, yield of leaves dried air weight /fed., number ofroots/plant) as well as chemical constituents (essential oil %, oil yieldper plant or feddan, total carbohydrates, N, P, K, Fe and Zn content ofthe herb) were significantly increased by applying biofertilizer (activedry yeast spray), mineral "NPK" and organic manures. Similar resultswere observed by using combined treatments of active dry yeast withthe organic manures. Application of both mineral "NPK" or poultrymanure gave the best values of growth parameters (plant height,number of branch, fresh weight of herb, herb dried air yieldweight/plant, leaves dried air yield weight/fed. number of roots/plant)as well as chemical constituents (essential oil percentage, oil yield perplant and per feddan). Poultry manure gave the best results for N, P andK (%), Fe and Zn (mg/g). and total carbohydrate contents in the cutsthan the other treatments. In addition the effect of active dry yeastcombined with either mineral "NPK" or poultry manure wasstatistically insignificant on all studied growth parameters. So it couldbe recommended with using biofertilizer (active dry yeast spray) at rate2 g/L. combined with poultry manure at rate 25 m3/fed. to get thehighest growth rate of marjoram with favorable chemical constituents.
