Abstract

This study aimed to compare the growth and production of paprika (Capsicum annuum) planted directly on a coir substrate slab according to the bending methods. The existing root direction was bent to 0° (I-type), 90° (L-type), and 180° (U-type), respectively. The weekly average growth such as stem length, diameter, and leaf area tended to be the highest in the I-type bending, but there was no statistical difference. Root weight at 46 weeks after planting was also about 1.3 to 1.7 times heavier in the I-type than the L- and U-type bending. As the yield produced by 330 plants by bending methods, the initial yield was the highest in the U-bending, but then the highest in the I-bending. Accordingly, the total yield was the highest in I-bending. Consequently, when planting on coir substrates directly in paprika cultivation, the I-type bending should be considered most suitable for securing root and plant vigor in the early stages of planting and for enhancing fruiting stability.

코이어 배지를 이용한 파프리카 재배에서 직접 정식 시 절곡 방법에 따른 정식 후 초기 생육과 수확량을 비교하였다. 절곡 방법은 I-type(절곡각도 0°), 옆으로 뉘인 L-type(절곡각도 90°), 뒤집어서 뿌리가 위로 향하도록 하는 U-type(절곡각도 180°)로 하였다. 줄기 신장 및 직경, 엽면적의 주간 평균 발달량은 정식 후 초기에 다른 처리구에 비해 영양생장이 왕성하였던 I-type에서 가장 높았다. 정식 후 46주째의 뿌리 무게도 I-type 처리구에서 다른 처리구들에 비해 약 1.3－1.7배 정도 무거웠다. 처리구별로 330주에서 생산된 수확량은 각각 약 510, 420 및 480kg으로 I-type에서 가장 높았다. 따라서 코이어 배지를 활용한 파프리카 재배에서 직접 정식 시 정식 초기의 뿌리 활착 및 세력 확보, 그리고 이후 착과 안정성에서 I-type이 적합할 것으로 판단된다.
