Abstract
시설재배 참외재배시 적정 관비액 농도조성 결정을 위하여 질소, 인산, 칼리 3요인에 대한 참외 수량반응에 대하여 반응표면분석을 실시한 결과 최대 수량을 나타내는 관비액 농도는 질소 $108.3mg\;L^{-1}$, 인산 $54.8mg\;L^{-1}$, 칼리 $158.3mg\;L^{-1}$으로 조사되었고 참외의 최대수량은 $2,966.8kg\;10a^{-1}$으로 분석되었다. 관행재배에 비하여 관비재배시 인산흡수량 증가는 없었으나, 질소 관비처리시 관비재배 처리구에 비해 약 33.3%의 질소흡수량 증가가 있었으며 (p < 0.001), 칼리의 경우 관비 처리구는 약 15.7%의 칼리흡수량 증가가 있었다 (p < 0.01). 참외의 수량도 관비재배 처리구에서 $2,678{\pm}75.50kg\;10a^{-1}$으로 관행처리구 $2,177{\pm}63.01kg\;10a^{-1}$보다 23% 정도 증수되었으며 (p<0.001), 관비처리와 관행처리간 토양화학성 차이는 없었다. Fertigation with drip irrigation provides effective and cost-efficient way to supply both nutrient and water to crop. However, inappropriate management of fertigation systems may cause inefficient nutrient and water use, thereby diminishing expected yield benefits as well as contributing to deterioration of soil properties. In this study, greenhouse experiments were conducted to investigate the optimal concentration of N, P and K fertigation solution for maximum production of oriental melon (Cucumis melo L.) using a response surface methodology, to evaluate an efficiency of nutrients uptake and an effect on soil chemical properties. Canonical analysis of response surface and contour plot interpretation revealed that $108.3mg\;L^{-1}$ of nitrogen (N), $54.8mg\;L^{-1}$ of phosphorous (P) and $158.3mg\;L^{-1}$ of potassium (K) resulted in maximim yield of oriental melon ($2,966kg\;10a^{-1}$). Compared to conventional practice, fertigation increased fruit yield up to 23.0% (p<0.001), uptake of N and K by plant also up to 33.3% (p<0.001) and 15.7% (p<0.01), respectively. These results suggest that fertigation has the advantage of the increase in yield and fertilizer use efficiency.
