In this study, the influence of four different sulfur products applied to the soil on the organically grown greenhouse tomato was investigated. The sulfur treatments were：（1） micronized-sulfur with bentonite （MSB） alone （90% sulfur ＋ 10% bentonite）; （2） MSB ＋ Fe （87% sulfur ＋ 10% bentonite ＋ 3% Fe）; （3） MSB ＋ Zn （87% sulfur ＋ 10% bentonite ＋ 3% Zn）; （4） MSB ＋ Fe ＋ Zn （86% sulfur ＋ 10% bentonite ＋ 2% Fe ＋ 2% Zn） and （5） control without sulfur treatment. The effects of sulfur products on plant growth, total crop yield, some fruit quality parameters, Fe and Zn content of the leaves and soil, pH and electrical conductivity （EC） of soil, were investigated. Results showed that the effects of treatments on plant growth parameters and fruit quality properties were not significant. However, total fruit yield increased by about 14%, 21%, 15% and 27% in MSB, MSB ＋ Fe, MSB ＋ Zn and MSB ＋ Fe ＋ Zn, respectively, as compared with control. Leaves Fe and Zn content were increased in some sampling times in related treatments. Soil Fe content was not changed by the treatments, however Zn content was significantly increased by the MSB ＋ Zn and MSB ＋ Fe ＋ Zn applications. Soil pH was decreased by the all sulfur treatments in comparison to control; however the most important pH decrease was recorded as 0.28 units in MSB ＋ Fe ＋ Zn treatment. Soil EC values of the all sulfur treatments were higher than the control.
