Soil pH has an effect not only on the growth and production of tomatoes but also has an influence on sugar metabolism. How the pH influences a production and the change of the sugar is still unknown. Therefore, this study aims to determine the effect of the soil pH on the carbohydrate content of tomatoes in Bobo and Sidera villages. The method used was quasi-experiment because the researchers did not randomly select tomatoes for the experimental group and the control group, but the researchers used tomato plants in the two villages that have the differences in the pH of the soil. The data obtained were analyzed using ANAVA assisted by XL STAT 2017 program. The results showed that the soil pH affected the carbohydrate content of tomato fruit found in Bobo and Sidera Villages. The pH of the soil in Sidera Village was lower than the pH found in the village of Bobo.
