To investigate the effect of biochar application on growth, physiological, and biochemical characteristics of Camelina under salinity stress, a two-factor factorial experiment was conducted in a randomized complete block design (RCBD) with three replications in the greenhouse of Payame Noor University of Lorestan during the 2022–2023 growing season. The experimental treatments included salinity stress at three levels (0, 6, and 12 dS/m) and biochar application at three levels (0, 1, and 2% w/w of soil per pot). The results indicated that the highest mean grain yield per plant was observed under the treatments of 1% and 2% biochar application in non-saline conditions (4.3 and 5.3 g per plant, respectively), as well as 2% biochar application under 6 dS/m salinity stress (3.1 g per plant). The mean stomatal conductance under 6 and 12 dS/m salinity levels reached 52.7 and 36.9 mmol m⁻² s⁻¹, respectively. In contrast, the application of 1% and 2% biochar increased stomatal conductance by 10% and 25%, respectively. Potassium content decreased by 14% and 35% under 6 and 12 dS/m salinity levels, respectively, whereas sodium content increased by 135% under 12 dS/m salinity stress. In contrast, biochar application led to an increase in potassium content and a decrease in sodium content. The highest potassium concentration was observed with the 2% w/w biochar treatment (41.9 mg/g dry weight), while the lowest sodium content was also recorded under the 2% w/w biochar treatment (10 mg/g dry weight).
