A factorial experiment was carried out by foliar application of zinc in two forms zinc sulphate (ZnSO4) and zinc oxide nanoparticles (ZnO NPs) prepared from aqueous zinc acetate using a wet chemistry method, which were characterized using an atomic force microscope (AFM) as having dimensions of 40-80 nanometres. The foliar of two zinc forms were applied in three concentrations (25, 50 and 100 ppm) in addition to distilled water with the aim of studying their effect on the growth and productivity of durum wheat plants ( Triticum durum, L var. Sham 7) grown under the conditions of Deir Ez-Zor Governorate-Syria. The results showed that adding zinc had a significant effect on all tested morphological indicators (plant heights - chlorophyll - number of branches/plant - number of spikes /plant) and productivity (1000 kernel weight, grain and straw productivity), as well as the grain content of some elements (nitrogen, phosphorus, potassium and zinc). The treatments for adding zinc oxide nanoparticles were significantly superior to those of zinc sulphate in all tested indicators. as the lowest values for the tested indicators were recorded in the regular zinc sulphate treatment at a concentration of 25 ppm compared to the rest of the treatments except for the control treatment, while the Nano zinc oxide treatments at a concentration of 50 and 100 ppm showed superiority significantly in all studied indicators especially in increasing wheat productivity by 24- 26%, compared to the control treatment.
