Abstract

Introduction: High bicarbonate induced by soil and water alkalinity is a limiting factor of agricultural crop production especially in arid and semi-arid regions of Iran. Materials and Methods: A factorial experiment based on completely randomized design was carried out to evaluation of effects of Nitrogen source on growth parameters and nutrient contents of arial parts of garlic under alkalinity conditions in hydroponic system. The factors of the experiment were including: Sodium bicarbonate (0, 10 and 20 mM), Nitrogen source in nutrient solution (Ammonium sulfate, Ammonium nitrate or calcium nitrate at 5 mM) and Garlic genotypes (white and purple). In the experiment, one-month genotypes of garlic were treated in hydroponics system for 8 weeks. Results and Discussion: Based on the results, shoot and root fresh and dry weight of plants decreased by increasing Sodium bicarbonate from 10 mM to 20 mM in nutrient solution. Application of Ammonium nitrate and sulfate decreased the negative effect of Sodium bicarbonate on shoot and root fresh and dry weights. The results showed that Nitrogen and potassium concentrations in plants nourished with Ammonium sulfate or nitrate were increased by increasing bicarbonate level in nutrient solution. Also, calcium and magnesium concentrations in the plants treated by Ammonium sulfate and calcium nitrate were increased under these conditions in both genotypes, while iron concentration in all of Nitrogen sources decreased with bicarbonate stress. Conclution: According to the results of the experiment, the use of Ammonium sulfate and nitrate sources had a better efficiency on nutrients uptake and concentration in shoot of garlic under high bicarbonate conditions.
