Sweet corn production and productivity in Riau has fluctuated due to changes in harvested land area. Solution to increase sweet corn production and productivity is to expand planting area to peaty land and use superior varieties. Problems on peaty land can be solved with EFB (Empty Fruit Bunch) ash. Assembly of superior varieties can be done through correlation and path-analysis. Research aimed to determine relationship, direct and indirect effects of sweet corn with various doses of EFB ash on peaty land. Research was conducted from December 2023 to April 2024 using the factorial RBD (Randomized Block Design) with two factors: sweet corn varieties (Bonanza, Kumala, Golden Boy, and Paragon) and ash (no ash; 1,5 t.ha-1; 3 t.ha-1 and 4,5 t.ha-1). Parameters observed were time to complete blooming male flowers, time appearance female flowers, plant height, stem diameter, harvest age, diameter cob without husk, length cob without husk, weight cob without husk, number rows seeds and yeild. Correlation results showed that characters of plant height, stem diameter, harvest age, diameter cob without husk, length cob without husk, weight cob without husk, number seed rows had positive correlation with yield. The weight cob without husk is character that has the greatest direct effect on character of fruit weight per plot. The length cob without husk has the greatest indirect effect value on yield through character of weight cob without husk.
