e0“Four soybean varieties in pure stand and mixtures were grown in 20 competition treatments of genotypes at within-row spacings of 5, 10, 20, 40, and 80 cm”
e5“Height and number of branches were increased as within-row spacings were increased. Seed yield per area was increased oppositely”

Other claims from this paper (13)
- Intervention effect Within-row spacing treatment had highly significant effects on yield, 100-seed weight and height of soybean.
- Intervention effect Within-row spacing treatment had highly significant effects on branch number, pods per plant and seeds per pod of soybean.
- Intervention effect Height and number of branches of soybean increased as within-row spacing increased.
- Intervention effect Within-row spacing had no effect on number of nodes and days to flowering of soybean.
- Intervention effect Maturity of soybean did not respond equally to spacing among the four varieties.
- Intervention effect Fruiting period of soybean was influenced by spacing treatment.
- Intervention effect Fertilizing and non-fertilizing treatments did not differ significantly in soybean.
- Intervention effect At 80 cm spacing no competition effect occurred for soybean yield.
- Observation Kumkang Daerip was a strong competitor among the soybean genotypes.
- Observation Chungbuck Back and Shelby were weak competitors among the soybean genotypes.
- Recommendation A within-row spacing of 20 cm was recommended to increase yield per area of soybean.
- Intervention effect Oil percent of soybean increased as spacing increased.
- Intervention effect Protein percent of soybean increased as spacing decreased.
