| This research was conducted as factorial layout in a randomized complete block design with three replications in the research fields of Baye-Kala Agricultural Research Station (BARS) at Neka city in 2021-2022. The treatments included four levels of salicylic acid (1, 0.5, 1, and 1.5 mM) and four levels of titanium oxide nanoparticle (0, 100, 200, and 300 ppm) which used as foliar at vegetative growth. The mean comparison of the simple effect of treatments showed that the grain yield and plant dry weight were increased by increasing the concentration of titanium nanoparticles and salicylic acid. At 300 ppm titanium nanoparticles and 1.5 mM salicylic acid, the highest grain yield and plant dry weight were 0.24 kg/ha and 0.26 kg/ha. The grain yield and plant dry weight were increased 46% and 37%, respectively using 300 ppm titanium nanoparticle. In addition, the enhancement of 66% and 72% of grain yield and plant dry weight, respectively were obtained by application of 1.5 mM salicylic acid. The highest amount of chlorophyll a, b and total (0.447, 2.173, 2.620 mg/g of fresh tissue), flavonoid (22.22 mg/g of fresh tissue), catalase and peroxidase (2.33 and 4.12 absorption units per microgram of protein per minute and soluble sugar (162.04 mg/g of fresh tissue was related to the treatment of 300 ppm titanium nanoparticles and 1.5 mM salicylic acid. Based on the obtained result, the effect of two elicitors used caused increase in physiologic traits and grain yield of camelina. |
