Two field experiments on soybean (Glycine max L.; Variety Giza, 111) wheat (Triticum aestivum L.; Variety Misr 1), were conducted at Agricultural Experimental Research Station of Tag El-ezz, Agricultural Research Centre, El-Dakhalia Governorate, Egypt during two successive summer - winter seasons of  (May to November 2019) to (November 2019 to May 2020). The experiment treatments were included eleven (11) treatments (T₁- Absolute control, T₂- 100% RDUF(recommended dose of urea fertilizer), T₃- 100% RDCUF (recommended dose of coated urea fertilizer), T₄- 75% RDUF+ 20m³ farm yard manure (FYM), T₅- 75% RDUF+10 m³ FYM, T₆- 50% RDUF+20m³ FYM, T₇- 50% RDUF+10m³ FYM, T₈- 75% RDCUF+20m³ FYM, T₉- 75% RDCUF +10m³ FYM, T₁₀- 50% RDCUF+20m³ FYM, T₁₁- 50% RDCUF +10m³ FYM).The treatments were layout in complete randomize block plot design with three replicates. The results indicated that the highest mean values of vegetative growth stage (N, P and K % and chlorophyll a, b and Carotene), chemical content of harvest stage(N, P and K % in soybean hay and seeds or wheat grains and straw) and protein%,  as well as yield and its components (plant height cm, hay, seeds ton fed^-1 and 100 seed weight of soybean or straw, grains yield ton fed^-1 and1000 grain weight of wheat) were recorded with integrated application of inorganic and organic fertilizers. T₈- 75% RDCUF+ 20m³ FYM, was considered as most suitable treatment for obtaining the highest yield of soybean –wheat under these experimental conditions.
