Sweet corn requires large nutrients for growth and production. Legume compost can be used as fertilizer to fulfill nutrients that are beneficial for plant growth. The use of legume compost can substitute NPK elements which function for plant growth. Other efforts that can be made to increase sweet corn production due to the narrowing of agricultural land are to increase the plant population, which is usually 1 plant per planting hole can now be added to 2 to 3 plants per planting hole. The purpose of this study was to determine the best dosage combination of legume compost with the number of plants per planting hole. The research was conducted in an experimental field in Politeknik Negeri Jember. The study was conducted using a factorial randomized block design (RBD) with 2 factors, namely the dose of legume compost and the number of plants per planting hole. From this study there were 9 treatment combinations and 3 replications so that there were 27 experimental units. Anova test results showed that the treatment of legume compost dosage and the number of plants per planting hole had no significant effect on the parameters of plant height, number of leaves, corn cob length, corn cob weight, corn cob diameter, and sweetness level, but had significant effect on the parameter of corn cob production per unit observation.
