Information on the combined effect of enriched paddy straw compost and potassium fertilizer is required for tropical regions. The objective of this research was to study the application of plant compost (paddy straw (Oryza sativa) compost and enriched paddy straw compost) and potassium fertilizers doses on the growth and yield of sweet corn. The experiment was conducted in Bandar Lampung, Indonesia from December 2014 until March 2015. The experimental design was a factorial design 2×3 within a completely randomized block design with 3 replications. The first factor was the type of plant compost and the second factor was the potassium fertilizers doses. Chicken manure and dolomite were added to enrich the quality of the compost. The experiment showed that enriched paddy straw compost promoted a steady better growth and higher yield of sweet corn than standard paddy straw compost. The application of potassium fertilizers combined with enriched paddy straw compost showed the best growth and N, P, K uptake. In consequence, application of compost for sweet corn can be adapted with material in situ such as straw paddy rice.
