AB - 수박 휴작기에 풋거름 작물로 헤어리베치와 호밀을 재배한 후 토양으로의 환원이 후작물 수박의 생육과 수량 그리고 토양의 질산태질소 함량에 미치는 영향을 구명하고자 하였다. 파종 후 151일간 재배한 후에 헤어리베치와 호밀의 토양 질소 환원량은 각각 79 kg/ha와 88 kg/ha였다. 헤어리베치와 호밀은 시설하우스 한 동씩 두 동의 면적에 풋거름 작물구, 풋거름작물에 요소 25%, 50%, 75% 처리구, 요소 100% 등 5처리를 각각 두었다. 수박의 생육은 각각의 헤어리베치 및 호밀 처리에서 동일한 생육을 나타냈고 수박의 수량에서도 처리간의 통계적인 유의성은 없었다. 토양의 질산태 질소함량은 수박 정식 후 재배일수가 증가할수록 지속적으로 감소하여 정식 후 75일째에 가장 낮은 함량을 나타내었는데 호밀처리구는 호밀만 투입만 처리가 52 mg/kg으로 가장 낮았고, 헤어리베치 처리간 비교에서도 마찬가지로 헤어리베치만 공급한 처리가 가장 낮은 44 mg/kg이었다. 헤어리베치와 호밀 등 녹비작물만의 투입으로도 수박의 재배기간 동안에 토양의 질산태 질소가 40 mg/kg 이상으로 존재하여 화학비료의 추가적인 시비 없이도 동일한 생육을 보인 것으로 판단되었다. 하지만 수박의 수량과 재배기간에의 토양 중 질산태질소와의 관계에 대한 추가적인 연구가 필요할 것으로 사료된다.BACKGROUND:In this study, we evaluated the effects of soil incorporation of hairy vetch (HV) or ryeas a green manure on the growth and yields of watermelon and soil nitrate nitrogen in a green house.METHODS AND RESULTS:HV and rye were cultivated for 151 days after sowing on October 30th and incorporated into soil before transplanting watermelon. The amount of N added by soil incorporation of HV and rye were 79 kg/ha and 88 kg/ha, respectively. Five different N treatments for each of HV and rye were included as follows: green manure, green manure with urea at 25%, 50%or 75%, and 100% ureafor the N recommendation rate. The growth and fruit yield of watermelon were not different among the treatments of both HV and rye. Soil nitrate N content at both HV and rye treatments decreased continuously with the lapse of days after planting (DAP) and was lowest at 75 DAP: 44 mg/kg and 52 mg/kg the for the HV and rye treatment without urea, respectively.CONCLUSION:These results indicate that the N mineralized from the soil incorporated HV or rye accounts for an important portion of N available for the growth and fruit yield of watermelon. It can be suggested that the green manures, comparable to ureacould ensure the yield of watermelon, if soil nitrate N content isabove 40 mg/kg by soil incorporation of HV and rye during watermelon cultivation. However, further studies on the relationship between soil nitrate N content during cultivation periods and the fruit yield of watermelon are required.
