Abstract
Background & Objective: The use of chemical fertilizers has created environmental problems. Therefore, the application of organic fertilizers can be considered a suitable solution to maintain soil fertility and increase fertilizer productivity.
Materials & Methods: To investigate the effect of organic and chemical fertilizers on the growth and field performance of faba bean (Vicia faba L.), an experiment was conducted with a randomized Complete Block Design (RCB) with three replications in 2021 at the research farm of the Faculty of Agriculture at Tabriz University. In this experiment, the treatments included four different sources of fertilizers, including the application of nitrogenous chemical fertilizer in the form of urea (50 kg ha-1), leaf mould (5 tons ha-1), farmyard manure (8 tons ha-1), vermicompost (5 tons ha-1) and control.
Results: The highest chlorophyll index, plant height, number of pods per plant, 100-grain weight, grain yield, and biomass were obtained from urea fertilizer application treatment which was not significantly superior to other treatments. in terms of leaf area index and the number of leaves per plant, the application of farmyard manure was significantly superior to other treatments.
Conclusion: In order to produce more biomass and grain yield in faba bean, two treatments of urea and farmyard manure were identified as the most favorable nutritional treatments. The application of farmyard manure at a rate of 8 tons ha-1, in addition improving crop production, can replace the application of nitrogenous chemical fertilizers.
