This research was done to investigate the effects of Nano-iron spray, the chemical synthesis of silver nanoparticles and the green synthesis of silver nanoparticles on chamomile plant( Tanacetum parthenium). It was done in the form of a completely random factorial design with three replications in the greenhouse of the agricultural college of Zabol university. The treatments included the first factor , Water dificit stress in two levels (non-stress and moderate stress , %50 of the field capacity) and the second one included nanoparticles in three levels of Nano-iron, the chemical synthesis of silver nanoparticles and the green synthesis with the density of 30ppm and one non-Nano level. In this research, the proline traits, flavonoid, the soluble carbohydrates in stem, chlorophyll A, chlorophyll B, the total chlorophyll, the carotenoids and the amount of the parthenolide active substance were evaluated by high performance liquid chromatography . The results of the variance analysis showed that the effect of drought stress on all of the studied characteristics is significant at the %1 level. Moreover, the foliar feeding of the nanoparticles had positive and significant effects on the investigating  traits. The effects of the interaction between the nanoparticles and the drought stress on the investigating traits became significant statistically. In general, it can be said that the green synthesis of nano silver spray in the photosynthetic pigments traits, the soluble sugar content, proline, flavonoids and parthenolide was variable. But, it increases the maximum economical performance of chamomile plant. (The amount of pathenolide).
