The effects of lacking and overplus of manganese (Mn) on the yield and the quality of the tomato were researched by designing different concentration of manganese sulfate and determining the yield and the items related to flavor quality under different Mn concentration. The results showed that both lacking and overplus of the Mn could decrease the chlorophyll content and the yield significantly, the chlorophyll content were 57.31% and 61.50% as the control separately, the yield were 58.25% and 68.35%; SOD and POD activity in the leaves were decreased, but the MDA content were increased by 71.07% and 40.71% respectively. In the fruit two treatments made the acid increase 37.4% and 40.1%, soluble substance decrease 17.51% and 13.19%, Vc content decrease 31.94% and 9.45% separately. Moreover the lycopene content decreased by about 34%, the content of total phenolics and total flavonoid decreased by 30%-35%, antioxidative capacity were also been decreased significantly. In addition, the types of the aroma compounds in the fruit treated by 2 treatments were less than the control. These results indicated that suitable manganese is the guarantee of high yield and quality of the tomato.
