Waste nutrient solution(WNS) using non-recycled hydroponics for melon increased contents of $NO_3$-N and cataions, such as, Ca, K, while anions except $NO_3$-N were decreased slightly as the musk melon plants grew. pH and EC of WNS were maintained 5.7$\sim$7.0, 2.0$\sim$2.2 $dS{\cdot}m^{-1}$, respectively. The musk melon plants cultivated by fertigation using WNS showed longer plant height and root length, and higher chlorophyll content than that grown by hydroponics. The fruit weight of musk melon grown by fertigation using WNS were 417.1 g heavier than that cultivated by hydroponics and soluble solids contents of musk melon fruit cultivated by fertigation using WNS was $13.3^{\circ}Brix$, that was $1.4^{\circ}Brix$ higher than that grown by hydroponics. While the growth of cucumber plants and size of cucumber fruits were not different between in fertigation using WNS and hydroponics, total yields and marketable fruit percentage showed more in fertigation using WNS than in hydroponics.

가뭄이 매년 지속됨에 따라 고랭지배추 재배지에서도 관수의 필요성이 인식되면서 관수를 실시하고 있으며, 대부분 스프링클러로 관수하고, 분수호스나 점적호스도 일부 이용하고 있으나 아직 토양수분, 토성이나 작물상태, 재배시기 등 환경요인을 고려한 과학적인 수분관리가 이루어지지 못하고 있어 고품질 안정생산을 위해서는 수분관리의 과학화가 필요한 실정이다. 물을 최소화 하면서 관비가 가능한 점적 호스 재배는 적정한 비료를 필요한 위치에 공급하는 방식으로 비료의 효율을 높이면서 환경오염을 최소화하고, 비료과다 시용에 따른 환경오염 등을 회피할 수 있는 좋은 수단이다. 본 연구는 앞으로 고랭지배추 점적호스 재배시 가뭄 극복과 효율적인 시비를 위한 적정 관비횟수를 구명하고자 하였다. 배추품종은 수호를 이용하였으며 관비횟수는 2회(20일 간격), 3회(15일), 4회(10일), 6회(7일), 관행(추비3회) 등 5처리를 두었으며 기준시비량은 N-P-K=32.0-7.8-19.8kg/10a로 하였으며 관비농도는 EC 1.2 dS/m fh 하였다. 시험은 고령지농업연구소 시험포장에서 6월 하순부터 8월 상순까지 무멀칭 노지재배를 하였다. 관비는 정식후 7일째부터 주었으며 관비량은 1회 구당 20ℓ를 주었다. 시험구배치는 단구제 3반복으로 배치하였다. 생육시기별로 초장, 엽장, 엽폭 모두 관비횟수가 많은 처리에서 생육이 좋았으며 6회 처리가 가장 생육이 좋았다. 주당 외엽수와 내엽수는 관행보다는 관비횟수가 많을수록 많아져 관비 6회에서 주당 69.7매로 가장 많았으며 주중과 구중도 관행에 비해 관수횟수가 많아질수록 높아졌으며 관비 6회에서 주중은 2,439g, 구중은 1,917g 으로 높게 나타나, 고랭지배추 관비횟수는 EC 1.2 dS/m 농도에서 6회를 한 것이 생육이 양호하였다.

Experiments were conducted to investigate the effect of fertigation (fertilizer-added irrigation) on soil EC (electrical conductivity), nitrogen and calcium content in soil, vine growth and fruit yield of oriental melon (Cucumis melo L. var. makuwa Mak.). Soil EC was increased with the frequency of fertigation (Yamazaki's solution for melon, 900 L/1,000 plants, each time) up to $0.8dS{\cdot}m^{-1}$ as compared to that of conventional irrigation ($0.2dS{\cdot}m^{-1}$). Ca content in soil also increased in fertigation fields. Vine dry weigh (20 days after planting) was significantly increased in fertigation plot. Markedly increases in marketable fruit yield and lower rate of off-shape fruit were recorded with the increase in fertigation frequency. Mean fruit weight and soluble solids contents ($^0Brix$) in fruit were not affected by fertigation. Fresh weight loss during storage was significantly higher in fruits harvested from 2 times fertigation (09:00 and 18:00) plot than conventional irrigation and the 1 time fertigation ones.

Salinity problems are caused from the accumulation of soluble salts in the root zone. These excess salts reduce plant growth and vigor by altering water uptake and causing ion-specific toxicities or imbalances. In this investigation, green pepper cultivation technique using mixture bed of soil and rice hull and surface drop fertigation system was examined to prolong the productivity of salt-affected plastic film house soils. Green pepper growth was better in the mixture bed of soil and rice hull comparing to the conventional soil cultivation. Especially root growth was much better and the root had more thin root system in the mixture bed of soil and rice hull. The better growth of root may be due to the better physical conditions and lower EC in the mixture bed of soil and rice hull where nutrient supply was well-managed with fertigation system. In the cultivation with mixture bed of soil and rice hull, fruit yield of green pepper was significantly higher; increased by 43% in comparison to the conventional soil cultivation. Pepper cultivation technique using mixture bed of soil and rice hull and surface drop fertigation system is expected to be a useful method for maintaining and prolonging the productivity of salt-affected plastic film house soils.

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.
