Abstract
This study was conducted to investigate the effects of different amounts of copper (Cu) and sulphur (S) applications on growth and nutrient contents of tomato plants grown in a computer-controlled greenhouse. Cu was applied to soil as CuSO 4 .5H 2 O in five levels (0, 250, 500, 1000 and 2000 mg kg -1 Cu) and elemental S in two levels (0 and 750 mg kg -1 ). The results showed that the plant height, leaf, stem and root dry weights decreased with Cu applications. The plant total N contents increased with Cu and S applications. With and without S application, the plant P contents decreased with Cu applications. The plant K contents decreased with Cu supply to soil. S application did not have an effect on the leaf and root K contents, but decreased in the stem samples. Leaf and stem Ca contents decreased with Cu and S applications while increased with Cu and S applications in root Ca content. Leaf Mg content increased with Cu application. Stem and root Mg contents decreased by Cu and S applications. Plant Fe contents decreased with Cu applications. Plant Mn contents increased with Cu and S application. Leaf and root Zn contents decreased with Cu application while increased with S application. Stem Zn contents increased with Cu and S applications. Plant Cu contents increased with Cu application. As a result, soil Cu treatment, aiming to control plant diseases, and S application, aiming to reduce soil pH, showed different effect on nutrient contents and negatively affected growth of tomato plants. Increasing Cu treatments to soil caused a decrease in root growth, reducing uptake of nutrients such as P, K, Ca, Fe and Zn. The combined applications of Cu and S to soil increased the toxicity of copper on tomato plants.
