Camelina (Cruciferae), is an oilseed. Chitosan is a natural biopolymer, non-toxic, and biocompatible which favors potentially broad application in biotic and abiotic stress. Iron is an essential micronutrient for almost all living organisms because it plays a critical role in metabolic processes respiration, and photosynthesis. In this research, examined the salinity (0, 8, 12, ds/m), (0, 5/12, 7/6 g/l) chitosan (0, 0.2, 0.4, g/l) and iron (0, 3, 6, g/l) based on a randomized block design with three replications. The sodium, root growth increased significantly in salinity. The irons and growth parameters decreased because the ionic ratio has been changed. Root increased to provide water. Due to the destructive effects of salinity, the increase of sodium has also affected other parameters and caused the decrease of iron and calcium. Stress has been reduced the shoot growth by affecting the growth of the plant. In this study, the interaction of salinity, chitosan, and iron, it was observed that the stem length, biomass, RWC, ions, carbohydrates increased and the root growth decreased. It has effect on RWC, regulating ions and compatible solutes, have been able to maintain the plant's conditions like stress-free conditions reduce the effects of salinity, and help plant growth.
