The present research evaluated the growth of green onion plants (Allium fistulosum, L.), cultivar Tokio Kuro, under contrasting nutrient solution concentrations (I - 50%, II - 75%, III - 100%, IV - 125%) and different positions on hydroponic channels (I - initial, II - intermediary, III - final). At the end of the growing cycle, the height, number of leaves, fresh leaf weight, and the tillering number of green onion plants were analyzed using univariate, multivariate analysis, and Pearson correlation. We noticed that green onion plants presented better height performance, the number of leaves, fresh leaf weight, and tillering number using nutrient solution concentration between 50 and 100%, making possible an earlier harvest. At 125 % nutrient solution concentration, there occurred a decrease in the number of leaves and fresh leaf weight. There are no significant differences between plants' positions on hydroponic channels for height, number of leaves, fresh leaf weight, and tillering number of green onion plants. Our finding suggests hydroponic cultivation of green onion is a great cultivation system, and concentration between 50 and 100% promote higher plant development and makes possible an earlier harvest.
