A study was conducted in Lamahi municipality of Dang district to compare the soil carbon stock under four different cropping system. Representative soil sample (n=120) from four different cropping system (Rice-Maize, Rice-Wheat, Rice-Mustard and Vegetable) and soil depths (0-20 cm, 20-40 cm and 40-60 cm) were collected using a purposive sampling technique. Soil carbon content was determined by Walkley and Black method. Soil carbon stock was statistically different (p<0.05) with the cropping system and soil depth. It was found the highest in Rice-Maize (35.03 t ha-1) followed by Rice-Wheat (29.52 t ha-1), Vegetable (27.16 t ha-1) and Rice-Mustard (21.01 t ha-1) cropping system. The soil carbon stock declined with the soil depth and was found the highest (39.09 t ha-1) at 0-20 cm depth. These results suggest that there is a need of long-term Rice-Maize cropping system with sustainable soil management practices as it has greater potential to store organic carbon as compared to the other three cropping system.
