N2  - A field trail was carried out to compare the single and combined effects of farmyard manure (FYM), ammonium nitrate (AN) and Rhizobium inoculation on yield performance and N uptake by faba bean grown on a calcareous soil. All treatments were arranged in a split-plot design with three replicates. Both fertilizers were addressed at a rate of 30 kg N/ fed. At fruiting and late ripe stages, random plants were sampled to evaluate the nodulation index, yield performance and N uptake. The results have shown that FYM promoted the nodulation index, expressed as nodules number and their massive growth, than AN-treated plants. The relative comparison between N-supplying sources proved that the advantages of FYM accounted for 67.9 and 82.9% for the respective trails. The corresponding benefits of Rhizobium treatment averaged 16.9% for the nodulations number and 5.1 for its weight. Similar trend was also noted on faba bean yield and its components, except the weight of 100-seed, but the response rate varied considerably among the studied trails. Relative to AN treatment, the stimulatory effects of FYM addition were, subsequently, 8.5, 17.4 and 5.5% for total biomass, seed yield and seed protein percentage. The comparable advantage, due to inoculation treatment averaged 8.7, 28.3 and 15.4% on the respective trails. Except the straw yield component, documented data showed marked significant differences on dry matter yield with variable degree of variations, due to the main effects of N-supplying sources , inoculation treatments and their interactions. The results reported on N content and its accumulation in pods and whole plant followed up the same trend. Based on the positive results detected on the 2-way interaction of our experimental data, it becomes evident that FYM is more creative to achieve optimal yield records and seed protein, when applied at a rate of about 7.0 ton/fed (30 kg N/fed) to the seed-inoculated faba bean grown in the calcareous soil. The reported data proved that FYM induced considerable reduction in soil reaction and NO3-N content in the soil rather than AN
