This research was conducted in order to investigate the effect of iron nanoparticle (INp) and Putrescine (Pu) on some Camelina traits as a factorial design in a randomized complete block design with three replications at Baye-Kola Agricultural Research Station (BARS) in 2021. The treatments included INp (0, 20, 40 and 60 ppm) and putrescine (0, 0.5, 1 and 1.5 mM). Variance analysis showed that the factors were significant on the amount of photosynthetic pigments and morphological traits. The results of the comparison of the simple effect of the treatments showed that the highest amount of chlorophyll a and carotenoid was in the vegetative stage and carotenoid in the reproductive stage at 60 ppm of INp and the highest amount of chlorophyll a at 1 mM Pu and the highest am ount of carotenoid at 1.5 mM Pu. The highest amounts of chlorophyll b and total pigments were observed in the vegetative stage in the treatment combination of 40 ppm INp with 1.5 mM Pu and in the reproductive stage in the treatment combination of 60 ppm INp with 1 mM Pu. The highest amount of yield, number of seeds per capsule and also, the high value of 1000 seed weight and plant height were observed in the treatment combination of 40 ppm INp with 1 mM Pu. In general, the interaction effect of 60 ppm of INp and different concentration of Pu had the best results, and the spraying of these stimulants can improve the yield of the Camelina plant.
