        The spectrum of this study was research on the closed hydroponic cultivation of netted melons (Cucumis melo L.) using coir substrate, analyzing the impact of this cultivation method on melon yield, fruit quality, and the efficiency of water and nutrient usage. The experimental results showed that the average fruit weight of the melons grown in a closed system was 71.4 g higher than that of the open system, and the fruit width was on average 0.2 cm larger, showing a statistically significant difference. However, there was no difference in the average sugar content of the fruit flesh and height. Although there is no substantial commercial difference, it is conjectured that the change in the macronutrients ratio in the irrigation has played a role in the statistically significant increase in fruit weight, which is attributed to changes in the crops' nutrient uptake concentrations. This necessitates further research for a more comprehensive understanding. In terms of the productivity of irrigation required to produce the fruit, applying the closed system resulted in an increase of 7.6 kg/ton compared to the open system, saving 31.6% of water resources. Additionally, in terms of nutrients, cultivating in a closed system allowed for savings of approximately 59, 25, 55, 83, 76, and 87% of N, P, K, Ca, Mg, and S, respectively, throughout the entire cultivation period. As the drainage was reused, the ratios of NO3 - and Ca2+ increased up to a maximum of 9.6 and 9.1%, respectively, while the ratios of other ions gradually decreased. In summary, these results suggest that closed hydroponic cultivation can effectively optimize the use of water and fertilizer while maintaining excellent fruit quality in melon cultivation.

        네트멜론에 있어서, 주당(株當) 엽수(葉數)를 22매(枚)로 제한하여 8, 10, 12, 14절의 1과착과와 8-9, 10-11, 12-13, 14-15절의 2과 착과구를 설치하고 각각 네트 발현(發現), 품질(品質) 및 수량(收量)에 미치는 영향(影響)이 어떠한지 알고자 '슈퍼VIP' 멜론을 이용하여 비닐하우스 내에서 춘작재배(春作栽培)로 시험하여 다음과 같은 결과(結果)를 얻었다. 1) 주당(株當) 1과(果) 착과(着果)는 착과절위(着果節位)에 관계없이 네트발현이 양호하였으며, 착과절위(着果節位)가 높을수록 과중(果重), 과장(果長), 과경(果徑), 과육(果肉)두께가 증가되었고, 당도(糖度)와 저장성(貯藏性)은 떨어졌다. 2) 주당(株當) 2과(果) 착과(着果)는 착과절위(着果節位)가 높을수록 네트 발현(發現)이 우수하였고, 당도(糖度), 과중(果重), 과장(果長), 과경(果徑), 과육(果肉)두께가 증가하였으나, 저장성(貯藏性)은 차이(差異)를 보이지 않았다. 3) 네트발현, 당도 저장성등 상품성(商品性)은 주당(株當) 1과(果) 착과(着果)가 2과(果) 착과(着果) 보다 뛰어났으며, 12절(節)에서 1과(果) 착과(着果)한 것이 가장 우수했다. 4) 수량성(收量性)은 주당(株當) 2과(果) 착과(着果)가 1과(果) 착과(着果)보다 증가(增加)하였다.
