In order to investigate the changes of biochemical traits and seed yield of cumin (Cuminum cyminum L.) by spraying of titanium nanoparticle in different growth stages of the plant, a factorial experiment based on a complete randomized block design with four replications was done, in the years of 2013 and 2014, at Garmsar- Iran. Treatments used in this experiment consisted of various concentrations of titanium dioxide nanoparticle (0, 0.02%, 0.04% and 0.06%) and time of spraying of this nano particle (foliar application in vegetative and reproductive stages). In this test characteristics of soluble proteins, soluble sugars, catalase enzyme activity and seed yield were evaluated. Analysis of variance showed that the effects of concentrations of titanium dioxide nanoparticles were significant on all traits and simple effect of spraying times on the characteristics of soluble sugars was significant. However, the interaction’s effect of titanium dioxide concentrations and times of spraying on all characteristics was not significant. In general, the results of this experiment showed that spraying of cumin plants with titanium doxide nanparticle had a positive effect on the biochemical traits of the plant in comparison with the control (no foliar application) treatment, therefore the use of this nanoparticle increased the yield of this plant.
