Under the agro-ecological conditions of Mongolia, agricultural enterprises and individual farmers cultivating potatoes and vegetables have the potential to achieve stable yields. However, in recent years, declining soil fertility and increasing dependence on mineral fertilizers have highlighted the need to expand the use of naturally derived organic fertilizers. Compost, which contains essential macro- and micro-nutrients, has shown positive effects on crop performance in international studies. Given Mongolia’s increasingly arid climate, determining an optimal compost application rate is crucial for promoting ecological and sustainable agriculture. This study evaluated the effect of compost on potato (Gala variety) yield and aimed to identify an appropriate application rate under Mongolian field conditions. The research was conducted in 2021 at the experimental field of Polytechnic College in Mandal soum, Selenge Province, using four compost treatments (0, 5, 10, and 15 t/ha) arranged in a Latin square design with four replications. Results indicated that compost rates of 5–15 t/ha produced standard tuber yields ranging from 224.3 to 254.0 c/ha, with the 10 and 15 t/ha treatments achieving the highest yields (247.9–254.0 c/ha). Compost application at 15 t/ha increased total yield by 101 c/ha compared with the unfertilized control. Based on these findings, compost application, particularly at 10–15 t/ha, is recommended to improve potato yield while supporting soil health in similar agro-ecological environments.
