Most of promising lands in El-Arish are situated near the Mediterranean Sea, as insufficient available water irrigation with high concentration of salinity from wells water is generally used for irrigation. Production of medicinal and aromatic plants using microorganisms in biofertilization to reduce or replace the chemical fertilizers became an essential process to ensure safety for human and environment. The effect of three irrigation intervals (7, 14 and 21 days) and half or full dose of recommended rate inorganic NPK fertilizer as compared with control ones (recommended rate of inorganic NPK fertilizer without microbial inoculation) on vegetative growth, chemical composition and essential oil productivity of Achillea santolina L. Plants was studies at the Experimental Farm of the Faculty of Environmental Agriculture Science, El-Arish, during two seasons (2010/2011 and 2011/2012). Results showed that the moderate irrigation interval every 14-days was the prior for producing higher percentage and yield of volatile than the intervals every 7 and 21 days. The growth and yield parameters of the plants increased as a result of inoculation of symbiotic N2-fixers+phosphobacteria with inorganic fertilizer followed by the same mixture given half dose NPK fertilizer and then control. The interaction between the two factors of study, it could be noticed that growth and yield parameters considerably improved as a result of watering interval at 14 days and inoculation with biofertilizeres and supplemented with half or full dose of inorganic NPK-fertilizer in the two seasons.
