A field experiment was carried out at EI- Makrany Village, Yousef EI- Sadeek District, El- Fayoum Governorate during the two successive seasons of 200812009 and 200912010 to study the effect of inoculation with biofertilizer (cerealin), nitrogen and potassium fertilization at rates of 50, 75 and 100% of the recommended rate /fed. with foliar spraying of micronutrients (Fe, Zn and Mn) and their interactions on plant growth, yield and its components as well as chemical composition of wheat plants (c.v. Sakha 93) Application of the tested rates of nitrogen and potassium induced significant increase in vegetative characteristics (plant height, fresh and dry weight /plant, 1000-grain weight, grain weight /spike, grain and straw yield/fed.) as well as N,P and k content in the grains and straw and micronutrients uptake in the grains. Also, plant height, chlorophyll content, fresh and dry weights / plant, grain and straw yield/fed., and N,P and K uptake in grains and straw, micronutrients contents (Fe, Zn and Mn) in grains gave the highest values with inoculation by biofertilizer (cerealin) and foliar spraying of micronutrients The interaction between NK, inoculation by cerealin and micronutrients gave the highest values of vegetative growth characteristics, and N, P and K content in grains and straw and micronutrients (Fe, Zn and Mn) in grains when wheat plant was fertilized with 75% or 100% NK of the recommended rate and inoculation with cerealin plus foliar spraying by micronutrients as well as grains and straw yield/fed., protein content of grain, N, P and K uptake of both grain and straw, while the lowest values were recorded with 50% NK of recommended rates alone. Generally, the best results were obtained when wheat received 75% or 100% of NK of the recommended rate, inoculated by cerealin and sprayed with micronutrients. These treatments resulted in the highest yield and its components.
