In: Mansoura University Journal of Soil Sciences and Agirucultural Engineering 2011.v.2(7)Summary: This study was conducted during winter seasons of (2009-2010) and (2010¬-2011) at Meet Louza Village, Mansoura Province, Dakahlia Governorate, Egypt on a silty clay soil to find out the residual effect rice N-biofertilization on the next wheat crop (Triticum aestivum L. c.v. sakha 93). Biofertilization 8 treatments involving inoculums of Azolla (AzI), Azospirillum (Azs), Azotobacter (Azt), and Cyanobacreria (Cyn) as well as mixtures (AzI + Azs), (AzI + Azt), (Azs + Azt) and (Cyn + Azt) which take the same location with the same layout of the experimental field for the previous crop (rice), soil N- fertilization (4 treatments of control, 12.5 %, 18.75 and 25 % of N-recommended level 75 kg N fed-' as urea) were tasted in a split plot design with three replicates.
