In order to investigate the effect of different levels of potassium fertilizer and cultivars on yield and yield components of faba bean, a study was conducted in a factorial design in a completely randomized block design with three replications. In this experiment, potassium fertilizer factor was measured at three levels: zero (control), 50 and 100 kg ha-1, and cultivar factor including two cultivars Blakat and Bashheri. The overall results of this experiment showed that plant height, number of tillers, number of seeds per pod, pod length and grain yield were affected by interaction of cultivar in potassium fertilizer. Characteristics of number of seeds per plant and pod weight were affected by cultivar effects. No pod numbers and 100 seed weight were affected by any of the treatments. The results of the comparison of the mean of traits showed that in terms of grain yield per plant, the effect of different treatments showed that in treatments of interactions of potassium fertilizers in cultivar, blakat had the highest grain yield (45.34 gr) and cultivar (100 kg.ha-1) Behsheri had the least seed yield per plant in fertilizer treatments of 50 kg / ha potassium fertilizer (17.09 g). In all of the studied traits, the blanche variety had a better reaction to Bashheri cultivar than potassium fertilizer treatment in Tonekabon region.
