Abstract

The goal of this study was to examine the growth and yield according to planting density in wide-row drill seeding cultivation suitable for mechanized harvesting. We evaluated effects depending on planting densities [row spacing (30, 40, 50, and 60 cm) and plant spacing (10, 15, and 20 cm)] and cultivars ('Hongeon' and 'Arari') on growth and yield of Adzuki Beans (Vigna angularis (Willd.) Ohwi Ohashi). When row spacing decreased, the stem length increased in 'Arari' but decreased in 'Hongeon.' The stem diameter and number of branches in both the cultivars decreased with a decrease in row spacing. The pod height increased with lower planting densities. The greatest height values recorded in 'Hongeon' and 'Arari' were 5.0 cm and 8.8 cm in $30{\times}10cm$ and $50{\times}10cm$ treatments, respectively. The number of pods and number of seeds in both cultivars tended to increase with a decrease in planting density. On the other hand, in 100-seed weight, there was a difference in planting density in 'Hongeon', but no difference in 'Arari'. The highest yield was at the planting density of $40{\times}15cm$ in both 'Hongeon' and 'Arari', $285kg{\cdot}10a^{-1}$ and $374kg{\cdot}10a^{-1}$.

본 연구는 건강 기능성 팥에 대한 소비자의 선호도가 높아지면서 수요와 재배면적이 점차 확대되고 있는 팥의 생산량 증대와 자급률 향상을 위한 체계적인 재배기술을 확립하기 위한 기초자료를 얻고자 기계화 수확에 적합한 넓은이랑 줄뿌림 재배시 재식밀도에 따른 생육 및 수량에 관한 연구를 수행하였다. 1. 경장은 주간거리가 짧아질수록 '아라리' 품종은 길어지는 경향을 보였으나, '홍언' 품종에서는 대체적으로 짧아지는 경향으로 나타났으며, 경태와 분지수에서는 두 품종 모두 주간거리가 짧아질수록 가늘어지거나 적어지는 경향이 나타났다. 2. 착협고는 재식거리가 짧을수록 높아지는 경향이 나타났으며 '홍언'에서는 $30{\times}10cm$ 처리구에서 5.0 cm로, '아라리'에서는 $30{\times}10cm$$50{\times}10cm$ 처리구에서 8.8 cm로 가장 높았다. 3. 주당협수와 주당립수는는 두 품종 모두 재식거리가 길어질수록 많아지는 경향이 나타났으며, 백립중에서는 '홍언'에서는 재식밀도간의 차이가 나타났으나, '아라리' 에서는 재식밀도간 차이는 나타나지 않았다. 4. 수량성은 조간거리 40cm${\times}$주간거리 15 cm 처리구에서 두 품종 모두 (285, $374kg{\cdot}10a^{-1}$) 가장 높았다.
