This investigation was conducted to evaluate the productivity of certain number of sunflower genotypes under different treatments of Nanoparticles of Zinc Oxide (ZnO NPs). Seventeen sunflower lines (S6 generation) were evaluated under three level of ZnO. Results indicate that Line 7 surpassed all the other genotypes in achene yield / plant and 100 achenes weight and occupied the fifth place for oil content. The highest mean values for all studied traits were obtained when plants were sprayed by 15 nm ZnO NPs, also spraying Zinc led to the early push of plants to flowering compared to plants that were not sprayed by it. Otherwise, the lowest achene yield obtained from Line 2 without ZnO NPs spray. Maximum oil content obtained from Line 7 when sprayed by 15 nm ZnO NPs. On the other hand, the minimum oil content obtained from Line 17 without ZnO NPs spray.
