A field experiment was conducted on 8/11/2023 in one of the agricultural nurseries in Al-Salihiyah district, affiliated with Al-Shamiyah district/Al-Qadisiyah governorate, during the winter agricultural season (2023-2024) with the aim of studying the effect of bulk and nano zinc on some growth characteristics of the crop and the chemical content of barley plants under the influence of salt stress. Characterization of XRD and SEM were done in this work,. The experiment was designed according to a Randomized Complete Block Design (RCBD) with a factorial organization for a factorial experiment with three factors; the first factor included three concentrations of bulk zinc (0, 1 and 2 g L-1), while the second factor included three concentrations of nano zinc (0, 1 and 2 mg L-1), and the third factor included three levels of salt stress (0, 6 and 8 g NaCl L-1) with three replications for each treatment. All combinations of the three factor treatments were distributed randomly within each block, including the entire experiment of 81 experimental units. The results were as follows: The significant effect of bulk zinc at a concentration of 1 g L-1 in recording the highest means nitrogen content of grains (1.75%), phosphorus content of grains (0.35%), zinc content of grains (27.64 μg g-1). The significant effect of nano zinc at a concentration of 1 mg L-1 in recording the highest means of grain content of nitrogen (1.75%), grain content of phosphorus (0.36%), grain content of zinc (26.47 μg g-1). The significant role of salt stress at a concentration of 8 g NaCl L-1 achieved the highest means grain nitrogen content (1.83%), grain phosphorus content (0.36%). The significant interaction between bulk zinc and nano zinc (AB) in combination (1 g L-1 bulk zinc × 1 mg L-1 nano zinc) achieved the highest means for grain phosphorus content (0.37%),  grain zinc content (34.54 μg g-1), While the double interaction in combination (1 g L-1 bulk zinc × 2 mg L-1 nano zinc) achieved the highest means for grain nitrogen content (1.89%).
