The aims of experiment is to identify and assess the effect of compost and biochar on the growth and yield of sweet corn. The experiment was conducted at the experimental farm Faculty of Agriculture Syiah Kuala University Darussalam Banda Aceh, and using a randomized factorial design 3 x 3 with three replications consisting of two factors, compost and biochar. Factors compost fertilizer consists of three levels are treatment without compost, compost 15 tons ha-1 and compost 30 tons ha-1. Biochar factor with 3 levels are without biochar, biochar 15 ton ha-1 and biochar 30 ton ha-1. The parameters observed were plant height at 15,30 and 45 days after planting, number of leaves at the age of 15.30 and 45 days after planting (DAP), cob diameter without cornhusk, cob diameter with cornhusk, cob weight without cornhusk, cob weight with cornhusk, cob long without cornhusk, cob long with cornhusk. In this research, the best dose of compost is used to support the growth and the result of sweet corn is 30 ton ha-1. Biochar doses tend to be better when it is in the treatment of 15 tons. The interaction between compost and biochar which gives the best result found in the combination treatment without 30 ton ha-1 of compost and biochar.
