A field experiment was conducted in the Experimental Farm of the Faculty of Agriculture, University of Khartoum at Shambat in order to study the response of common bean (Phaseolus vulgaris L.) to phosphorus as influenced by farmyard manure (FYM). The treatments consisted of two rates of 2 5 FYM (0 and 2.5 ton ha-1 ) and five levels of phosphorus (0, 50, 100, 150 and 200 kg P O ha-1). Triple 2 5 superphosphate (48% P O ) was used as a source of phosphorus in the experiment. The experiment was laid out in Split-plot design with four replicates. FYM treatments were allocated to the main-plots, whereas the phosphorus levels were allotted to the sub-plots. Seeds of common bean (cultivar Shendi) were inoculated with Rhizobium phaseoli strain USDA 2669 as a basic treatment. The results showed that, application of phosphorus and FYM increased all the parameters that were examined during the experiment but the increase was not significant. Phosphorus effects were sometimes erratic and inconsistent. In addition, there was a significant effect of the interaction between phosphorus and FYM on the shoot dry weight after ten weeks from sowing.
