본 연구는 답리작 사료작물인 호밀에 대한 돈분액비 시용시 돈분액비에 의한 화학비료 대치효과를 파악하기 위하여 돈분액비의 시용수준별 호밀의 생산성 및 지력증진에 미치는 영향을 조사하였다. 실험설계는 화학비료 3 요소구(200-150-150), 화학비료 대비 돈분액비 $100\%$ N, 돈분액비 $200\%$N 및 돈분액비 $100\%$N+1/2 화학비료로 하여 3년 동안 수행하였는데 그 결과는 다음과 같다. 돈분액비의 시용수준에 따른 호밀의 건물수량은 돈분액비 $100\%$+1/2 화학비료구, 액비 $200\%$구 및 화학비료 3 요소구의 순이었으며 돈분액비 $100\%$ 구가 가장 낮았으며, 조단백질 함량은 돈분액비 $200\%$ 구가 $10.53\%$로 가장 높았고 돈분액비 $100\%$+1/2 화학비료구와 화학비료 3 요소구는 비슷하였으며 돈분액비 $100\%$ 구가 $8.04\%$로 가장 낮았으나, NDF와 TDN 함량은 돈분액비의 시용수준이나 화학비료의 시용에 관계없이 서로간에 거의 차이를 나타내지 않았다. 호밀에 의한 N 생산량은 N 공급수준과 비례하여 돈분액비 $200\%$, 돈분액비 $100\%$+1/2 화학 비료구, 화학비료 3요소구 및 돈분액비 $100\%$ 구 순으로 높았다. 또한, 토양중 N 함량과 토양 유기물 함량은 돈분액비 시비 수준에 따라 영향을 받지 않았지만 시용년도가 진행될수록 토양 N 함량도 증가되었으나, P 함량은 액비시용수준이나 년차간에도 변화가 없었다.
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, $P_2O_5: 150,;K_2O: 150$ kg/ha; PS $100\%$ treatment, PS $200\%$ treatment and PS $100\%$ treatment with half of CF). 1. DM yields of rye revealed that there was an increase in order; PS $100\%$ treatment with half of chemical fertilizer (CF) > PS $200\%$ treatment > full of CF treatment > PS $100\%$ treatment. 2. Crude protein (CP) content was the highest with PS $200\%$ treatment ($10.53\%$) and followed by PS $100\%$ treatment with half of CF and full of CF treatment and the lowest with PS $100\%$ 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 $200\%$ treatment > PS $100\%$ treatment with half of CF > full of CF treatment > PS $100\%$ 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.
