The object of this study conducted to investigate the effect of paddy-upland rotation cropping system on soil properties and crop productivity in newly reclaimed tidal land. Five types of paddyupland rotation cropping system were evaluated : Rice-Rice (RR) Rice-Maize (RM), Mize-Maize (MM), Rice-Soybean (RS), Soybean-Soybean (SS). The soil bulk density was the lowest RM treatment, and soil pH was a tendency to be lower in all treatments of the paddy-upland rotation cropping system. RM treatment showed a higher moisture content and lower Electrical conductivity than RR treatment. Results of maize productivity in paddy-upland rotation cropping system, Except for the stem diameter growth, RM treatment showed good growth and productivity than MM treatment. Soybean growth and yield increased in the rotated upland cultivation from rice-paddy field compared to the SS treatment. But, overall treatments indicated poor growth and yield. In this study, we offer the effects of paddyupland rotation cropping system on the soil properties and upland crop growth and yield, and also out results can be provide supporting basic data that introduced paddy-upland rotation in reclaimed tidal land.

신간척지에서 총체사료용 벼 주요 품종들의 담수직파 적응성을 평가하기 위하여 2012~2013년에 시험한 결과를 요약하면 다음과 같다.1. 입모율은 녹양과 수원552호 48%, 목우, 목양 및 수원544호 40~42%이었다. 2. 출수기는 녹양과 목양 8월 26~27일, 수원552호와 수원544호 9월 1~5일, 목우 9월 15일이었다. 3. m2당 수수는 278~333개였으며, 도복은 수원552호에서경미하게 발생하고, 그 외 공시품종에서는 발생하지 않았다.4. ha당 건물수량은 목우와 수원552호 15.8~16.8톤, 수원544호, 목양 및 녹양 이 13.1~14.3톤이었다.5. 조단백질 함량은 4.5~6.4%, ADF 함량은 27.1~30.1%,NDF 함량은 49.2~53.9%, TDN 함량은 65.1~67.4%이었다.6. 따라서 신간척지에서 총체사료용 벼의 담수직파재배에 가장 적합한 품종은 목우와 수원552호 이었다.
