The treated plants outperformed the untreated plants in all examined attributes, the data showed. The findings revealed that the maximum plant height was 35.21 cm, the most leaves were 20,63, and the largest leaf area was 77.70. The highest fresh weight value was 19.46 g, followed by the highest dry weight value of 4.17 g. When treated with a concentration of 75 mg/L chelated iron nanoparticles, the greatest total value of chlorophyll (79.42), the largest percentage of the total elements N (3.63%), P (0.57%), and K (2.83%), and the highest percentage of carbs (36.96%) were obtained. The greatest protein value was 17.100%, followed by iron (166.47%) at a concentration of 50 mg/L of chelated iron nanoparticles, fat (10.52%), calcium (235.67%), sodium (1435.08%), zinc (46.52%), and zinc at a concentration of 25 mg/L of chelated iron nanoparticles.
