Popis:	Two field experiments were carried out in two sites of Noubaria Agricultural Research Station Farm. The investigated acidifying materials were sulphur, superphosphate and Phosphorine. The materials were mixed with cowpea seeds just before sowing in a rate 1 kg for seeds required to 1 fed (4200 m2) in the first experiment. Additions were 100, 30 and 1 kg S, P2O5 and Phosphorine/fed, respectively to soils before common bean planting in the second experiment where the two varieties Giza 3 and Giza 6 were put under investigation. The residual effect of the soil additions was investigated using bean as a test crop.
