Effects of Planting Density on Growth and Yield in Wide-Row Drill Seeding of Upright Type Adzuki Beans (Vigna angularis (Willd.) Ohwi Ohashi)
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 × 10 cm and 50 × 10 cm 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 40×15 cm in both ‘Hongeon’ and ‘Arari’, 285 kg ․ 10a-1 and 374 kg ․ 10a-1.
