Abstract
The experiment was carried out in the Horticulture and Forestry Division of the Directorate of Najaf province, during 2020-2021 season to examine the effect of spraying three concentrations of Nano amino acids on eggplant (0, 1 and 2 ml.L-1) and zinc (0, 75, 150 mg.L-1). Results showed that the treatment of 2ml.L-1 of Nano amino acids was achieved significant increasing in leaves content of nitrogen, potassium, zinc and total chlorophyll, and the fruits content of carbohydrates, protein, vitamin C, Solanine and Nitrate as it amounted 2.74, 2.98%, 14.25 mg.kg-1 dry weight, 86.30mg.100g-1 fresh weight, 13.85mg.g-1, 15.34%, 22.02mg.ml juice-1, 1804.5micro g.g-1 dry weight, 328.8mg.g-1 dry weight respectively compare to control treatment which recorded the lowest values of above traits. While, spraying eggplant with 150mg.L-1 concentration of zinc was significantly exceeded and recorded an increasing in leaves content of nitrogen, potassium, zinc and total chlorophyll and the fruits content of carbohydrates, protein, vitamin C, Solanine and Nitrate that amounted 2.30, 2.33% and 10.93mg.kg-1 dry weight, 75.44mg.100g-1 fresh weight, 1255mg.g-1, 12.78%, 20.34mg.100ml juice-1, 1646.3 micro g.g-1 dry weight, 298.8mg.g-1 dry weight in comparison with control treatment which decreased in the studied traits. The interaction between 2m.L-1 of Nano amino acids with 150mg.L-1 of zinc gave significant increasing in leaves content of nitrogen, potassium, zinc and total chlorophyll and the fruits content of carbohydrates, protein, vitamin C, Solanine and Nitrate, as it recorded 2.81, 3.12% and 16.33mg.kg-1 dry weight, 87.71mg.100g-1 fresh weight, 15.00mg.g-1, 15.87%, 23.45mg.100ml juice-1, 1989.2 micro g.g-1 dry weight, 367.9mg.g-1 dry weight compare to control treatment.
