Two field experiments were carried out on rosemary plants (Rosmarinus officinalis L.) at the experimental Baramoon Research Farm, Dakahlya Governorate, Egypt, during two successive seasons, 2010-2011 and 2011-2012, , to study the effect of different sources of organic manure (FYM) mixed of poultry and cattle manures, humic acid, biofertilization nitrogen fixing bacteria (microbein) and phosphate dissolving bacteria (phosphorein), as well as active dry yeast on vegetative growth, herb yield, essential oil production and chemical composition of plants.The results clear that in both seasons, all fertilizer treatments achieved significantly better growth and yield than the untreated plants (control) which received recommend dose of NPK.. Treatments included that plant biomass responded linearly to (FYM) application and most values of all measurements were realized at the rate of 30 m 3 /fed. than obtained at both 20, 10 m 3 /fed. in comparison with those of control plants in both seasons, respectively. Also, it is evident that the application of (FYM) at rates of 10, 20 and 30 m 3 /fed., interacted with combinations of both (phosphorein + microbein), (phosphorein + yeast) and (phosphorein + humic acid) improved significant increments in the all growth characters compared with control plants, and the highest one was realized with combination of (FYM) at rate of 30 m 3 /fed. + phosphorein + humic acid.These findings clearly indicate that phosphorein, humic acid and 30 m 3 /fed. of (FYM) could be used as traditional fertilizers instead of chemical ones and may consequently minimized pollution of agricultural environments.

A field experiment was carried out to investigate the role of some plant antioxidant materials such as Ascorbic, Glutathion, α-Tocopherol, Spermine in alleviating the harmful effects caused by soil salinity levels (2000,3000 and 5000mg/l) in wheat plant. The grain were pre-soaked then the plants sprayed with any of antioxidants used. It could be concluded that soil salinity stress especially high levels depressed all of growth parameters and yield coponents. The data also concluded that the different applied antioxidants could partially alleviate the harmful effect of salinity stress on growth and yield of wheat plant.
