In Korea, pepper cultivation fields are mostly located at mountain slopes or sloping field. Recently, pepper cultivation area using paddy-field has been increased. It is necessary to determine alternate fertilization methods for pepper cultivation in paddy field because pepper growth and development are influenced by environmental condition such as drought or waterlogging. Experimental plots were operated at 3 levels of fast-releasing fertilizer and 2 levels of slow-releasing fertilizer in paddy field and field conditions. Plant height, stem diameter, fruit weight, fruit length, and fruit diameter in accordance with the types and amount of fertilizer did not show significant differences. In the fast-releasing fertilizer plot, the yield of pepper increased as 14.4∼32.4% in paddy field than in field cultivation. In double level of slow-releasing fertilizer plot, the yield of paddy field cultivation increased 24.4% compared to field cultivation. The amount of capsaicinoids, with the exception of double level plot in fast-releasing fertilizer treatment, showed higher levels in paddy cultivation. The ASTA value is higher in paddy-field plot than the field cultivation in the slow-release fertilizer treatment. Based on the results of this study, double levels of slow-releasing fertilizer was evaluated as suitable fertilization scheme for stable pepper production in paddy field.
