Abstract

This study was conducted on paddy-land at Kimje, ChunBuk in Korea from Nov. 1999 to Nov. 2002. The aim of this study was to investigate the effect of pig slurry (PS) on dry matter (DM) yield, N yield and nutritive value of rye, and soil total nitrogen (TN), Phosphorus (P) and organic matter (OM) content. This experiment was consisted of 4 plot (chemical fertilizer; N: 100/100, kg/ha; PS treatment, PS treatment and PS treatment with half of CF). 1. DM yields of rye revealed that there was an increase in order; PS treatment with half of chemical fertilizer (CF) > PS treatment > full of CF treatment > PS treatment. 2. Crude protein (CP) content was the highest with PS treatment () and followed by PS treatment with half of CF and full of CF treatment and the lowest with PS treatment. 3. The contents of NDF and TDN were hardly influenced by PS and CF 4. N yields of rye revealed that there was an increase in order; PS treatment > PS treatment with half of CF > full of CF treatment > PS treatment. 5. The contents of TN and OM were not influenced by the application levels of PS. however, The TN content increased by the application of PS, as increasing the application period 6. P content of the soil was not affected by the application levels of PS during the experimental period.
