Abstract: 
In order to investigate the effects of iron and silver nanoparticles on morphological and physiological traits of borage (Borago officinalis L. ), an experiment was conducted as factorial based on randomized complete block design with three replications in 2016 at the University of Zabol. The identification of synthesized nanoparticles was performed using FT-IR infrared spectroscopy and scanning electron microscopy. The treatments included iron and silver nanoparticles with four levels (control, 40, 60, 80 ppm), sprayed together and separately in two stages. The results indicated that spraying iron and silver nanoparticles had significantly different effects on soluble carbohydrates, mucilage, chlorophyll a, carotenoids, leaf and branch number, inflorescence height, flower number, and dry flower weight. Iron and silver nanoparticles (80ppm) had the highest effect on the traits measured. In all traits measured, iron nanoparticles were more effective than silver nanoparticles except chlorophyll b. Simultaneous use of iron and silver nanoparticles showed different effects on all traits, so that the highest significant difference was recorded for iron and silver nanoparticles at 80ppm.
