Abstract :Since exogenous amino acid applications to agricultural plants provide ready mineral nutrition for plants, they are widely used to enhance the yield and quality of crops as well as to strengthen resistance to environmental impacts. In the present study, the effects of L-Glutamic acid insert ignore into journalissuearticles values(GLU); insert ignore into journalissuearticles values(100, 200, 400, 800, and 1000 mg L-1); treatments on the growth parameters, bulb yield, chemical contents, and weight loss of Taşköprü garlic were analyzed. Given the findings, 800 GLU dose was found to have the highest values in shoot length and width, fresh weight, width, and length of the bulb, length and of large and small cloves, and yield per plot. On the other hand, the lowest results in total free amino acid, nitrate, polyphenol, ascorbic acid, and % ash amounts were obtained with 400 GLU, while the maximum leaf length and width was obtained with 1000 GLU dose. The first and third weight losses were obtained in 100 GLU and control groups and the second weight loss value obtained in all groups were higher than in the control. Considering all the data, the doses of 800 GLU and 400 GLU yielded the most positive effect on growth parameters, bulb yield, and weight loss measurements in garlic, whereas the lowest level of effect was observed in the control and 100 GLU groups. In conclusion, it can be stated that the foliar application of L-Glutamic acid in garlic cultivation might increase the yield and quality.
