Abstract
Under the natural conditions of soil and climate in Der Azzur governorate, the experiment was carried out in pot size (1000) cm3 during the agricultural season (2018). The soil was clay, and some physical, chemical and fertility analyzes were conducted in order to study the effect of soil treatment with different concentrations of sulfur acid solutions, on some vegetative growth traits of tomato plants Lycopersicon esculentum (supermarimond) variety. The sulfur acid solutions concentrations were 0, 0.4, 0.8, 1.2, 1.6, and 2)%. The soil at each concentration treated with a solution concentration of (100) ml. The major nutrients were added at 15 ppm of (N, P, K), as urea (46% N), superphosphate (46% P2O5) and potassium sulfate (50% K2O), while the control treatment (0) was treated with (100) ml of distilled water only, and the major nutrients were added as in the other treatments. The experiment was designed in a randomized complete block design (RCBD) with three replicates. With the addition of 1.6% of sulfuric acid, the tomato gave the highest values of germination percentage, number and length of leaves, leaf area surface and fresh and dry weight /plant.
