摘要：Nanotechnology has been proved to be used in various fields. It can be used in increasing crop production and protection. Its applications has been spread globally in small concentrations .Nanofertilizer may be less expen-sive than traditional methods. In this study , an experiment was carried out in pots at the Technical Agricultural College in Mosul of Iraq ,to evaluate the efficiency of zinc and sulfur nanoparticles synthesized in Jordan , on plant yield , nitrogen % and protein % in seeds of broad bean (Vida faba L.). Results of the investigation showed the effect of zinc oxide nanoparticles as well high concentration of sulfur nanoparticles as nanofertiliz-er. Zinc 50 and sulfur 200 nanoparticles concentrations had significantly plant yield of broad bean more than the remained treatments, followed by sulfur 100, sulfur 50 and then control. Zinc 50 and sulfur 200 showed significantly the highest nitrogen %and protein %in broad bean seeds compared with the other treatments, but without significant differences.
