This study was conducted in Al-Alam district - Tikrit during the agricultural season 2021-2022, to study the efficiency of spraying Nano-fertilizers on the yield components and chemical content of seeds of barley plants grown in plastic pots. In this study, the NPK fertilizer was used after converting it into nanoparticles. Statistical analysis was conducted at (P≤0.05) level, and the results were as follows: The effect of the interaction between different concentrations of NPK and the number of times of spraying varied in the yield constituent traits. The characteristic of the number of spikes was not significantly affected by the concentrations and the number of sprinkles, while the weight of the spike and the weight of 100 grains, was affected, giving 0.26 and 5.15 grams, respectively. The results confirm the existence of a significant difference between the different concentrations of NPK Nano fertilizer and the number of times of spraying, as the concentration exceeded 2 gm with spraying twice in giving the highest percentages of each of N, P, K, Na, Ca, protein and carbohydrates in the seeds amounted to 1.47, 19.95, 0.21, 0.07, 9.18 and 4.67%, respectively.
