This study investigated the effects of soil properties on the yield of Tainan peanuts in Ban Fah Huan, Khaw Wang District, Yasothon Province. Samples were collected from 10 plots and measured for temperature (°C), pH, soil moisture (%), organic matter, available phosphorus, available potassium, soil structure, cohesion, texture, and color. The results showed that the optimal yield per rai was achieved at site 10, with an average temperature of 22.70°C at 5 cm and 21.67°C at 10 cm depth, an average pH of 5.8, and an average soil moisture of 7.53%. The organic matter content in the soil (6) is between 0.26 -2.12. The available phosphorus (P) content is between 0-25 mg/kg (mg kg-1). The available potassium content is between 59-130 mg kg (mg kg-1). The soil structure is lumpy, very compact, and the texture is sandy loam. The soil colors found are SYR2/4, 25YR5/10, 75YR2/4, 75YR3/8, 75YRS/6.
