Compost application is a promising approach to improve soil fertility and the sustainability of plant production, but different types of compost may vary in their efficiency. A field experiment was carried out to evaluate the effect of traditional compost, vermicompost, and material composted with additional effective microorganisms (EM) on faba bean yield and related properties. The compost treatments were applied at three nitrogen levels (18, 27, and 36 kg ha-1) and compared to mineral fertilizer alone or in combination with compost in a two-factor randomized complete block design with four replicates. The economic effects of the different composts were assessed using partial budget analysis. All three composts resulted in significantly higher grain and biomass yields, as well as nutrient uptake into grain compared to mineral fertilizer. This was reflected in a higher number of nodules and higher residual soil nitrogen in the compost treatments. However, EM and vermicompost...
