Abstract

The study was initiated at three rice paddy fields of each large-scale area environment-friendly agricultural district, Suncheon and Jangheung in Jeollanam-do, and Okcheon in Chungcheongbuk-do in 2016 to observe growth and nutrients in soil and rice in a season. Jangheung farm had two observed plots; conventional plots and conventional plots additionally fertilizing of 20% T-N with oil-cake. Soil pH, EC, and K concentration on June in Jangheung farm were significantly higher than those values observed in Suncheon and Okcheon farms. Annual rice T-N contents in the Jangheung farm were more than 80 g but decreased in a season. T-N concentration in rice was high in Jangheung farm but the concentrations of P and K were not significantly different among the three farms at harvest. Plant height was as low as 101 cm in Sunchon farm but high in the dry weight (72 g). Leaf SPAD was higher in Jangheung farm than those of other farms. Okcheon farm, with early cultivar 'Milky queen', produced high head rice of 93%, and high unhulled rice and the brown rice per ha. Therefore, the annual production income was as high as 26.7 million won per ha. However, nutrient (T-N + P + K) balance in Okcheon farm with high amount of fertilizer application were as high as 900 kg per ha. On the other hand, nutrient balance in Jangheung farm resulted in less than 300 kg.

전국 광역친환경 농업단지 중 전남 장흥과 순천 그리고 충북 옥천 3개소를 대상으로 논에서 재배된 벼의 시기별 생장과 무기성분을 조사하였다. 장흥 농가는 기본 시험구와 기본 시험구에 N(질소)를 20% 추가한 유박 추가 시비구를 포함하였다. 6월 토양의 pH와 EC 그리고 K 농도는 유박 추가 시비를 포함한 장흥 농가에서 유의성 있게 높게 나타났다. 토양 1kg당 시기별 무기태 N는 이앙 후 6월에 장흥 농가가 다른 농가보다 80 mg 이상으로 많았으나 재배시기가 경과함에 따라 감소하였다. 시기별 벼의 T-N농도는 최고 분얼기에 장흥 농가에서 높았으며 수확기에는 유의성 있는 차이가 관찰되지 않았다. 벼의 P 농도도 시간이 경과함에 따라 감소하는 경향을 보였으나 처리 간에 별다른 차이가 관찰되지 않았다. 초장은 순천 농가에서 재배된 벼가 101 cm로 작았으나 건물중은 72 g으로 높게 나타났다. SPAD는 장흥 농가에서 높은 수준을 보였다. 외래품종인 밀키퀸을 재배한 옥천 농가는 완전립이 93%로 정조중과 현미, 백미 모두 ha당 생산량이 크게 증가하여서 연간 조수입도 2,671만원으로 가장 높았다. 그러나 옥천 농가는 대량의 퇴비 시비로 수확 후 토양에 잔존하는 양분수지(T-N + P + K)가 ha당 900 kg 이상으로 높은 수준을 보인 반면에 장흥 농가는 300 kg으로 낮은 수준이 관찰되었다.
