Twenty cotton (Gossypium hirsutum L.) cultivars were grown for 60 days in a greenhouse on Keo silt loam soil (coarse-silty, mixed, thermic Dystric Fluventic Eutrochrept) low in available sulfur (S). Sulfur (CaSO4.2H2O) was applied at rates equal to 0, 30 and 60 mg kg-1 soil. Total dry matter of shoots, total S concentration in tissue, S uptake expressed in mg S plant-1 and the N/S ratios were evaluated. The addition of S prevented S deficiency in the plants and significantly increased dry matter yields. Shoot weight increases of all cotton cultivars were associated with increased S concentration and S uptake, and a decrease in N/S ratios. Minimum S concentration and N/S ratio in cotton plants for maximum dry matter weights were 1.8 g S kg-1 and 13.0, respectively. |
