초록

This study was carried out to examine the effect of cattle manure and chemical fertilizer application on productivity and nutritive value of silage corn in the reclaimed paddy field of Sukmoon at Dangjin Province in Korea. The cultivars of silage corn used in this experiment were Kwangpyungok and Pioneer(P32B33). The fertilizer was applied according to recommended dose of application. The reclaimed paddy field of Sukmoon was created for farming in 1985 and approximately 5 to 10 years ago rice was cultivated in full-scale. Recently, reclaimed paddy field of Sukmoon has a limitation to cultivate the crops, due to increased salinity caused by drought and poor drainage system. The total area of reclaimed paddy field of Sukmoon was 305 ha, and silage corn was sown on 149ha of the reclaimed paddy field in nine regions, such as Songsan 28 A and B, Songsan 27 A and B, Songsan 42 A, B and C, and Songsan 43 A and B. The productivity and nutritive value of corn were evaluated collected from each of nine experimental regions. Dry matter(DM) yields of P32B33 in Songsan 28 A and B, and Songsan 27 A were 13 to 15 ton/ha and it was increased 3 to 5 ton/ha as compared to those of Songsan 27 B. DM yields of Kwangpyungok in Songsan 42 A, and Songsan 43 A and B were 23 to 27 ton/ha and it was increased 15 to 16ton/ha as compared to Songsan 42 A and B. The nutritive value of corn was not significantly different between Kwangpyungok and P32B33, but the yield of Kwangpyungok corn silage was higher compared to P32B33. Therefore, this study suggests that good drainage system is important to maintain normal growth and productivity of corn in the reclaimed paddy field.
