e0“Soybean row spacing (19 vs. 38 vs. 76 cm) did not affect soybean yield, unless the reduction in row spacing was combined with an increased seeding density (65% greater yield with narrow-row soybean seeded at 682,500 vs. wide-row soybean seeded at 455,000 seeds ha −1)”

Other claims from this paper (9)
- Observation Volunteer B. napus produced about 830 seeds per plant in soybean field experiments.
- Observation Volunteer B. napus resulted in large seedbank inputs of about 20,300 seeds per m2.
- Observation Volunteer B. napus seedling recruitment differed between two classes of sites with average densities of 39 and 89 plants m-2.
- Intervention effect Weed management tools were more effective at sites with higher volunteer B. napus densities.
- Intervention effect Increased soybean seeding density raised soybean yield by 44% compared with 455,000 seeds ha -1.
- Intervention effect Interrow tillage raised soybean yield by 36% compared with no interrow tillage.
- Intervention effect Narrow-row soybean at 682,500 seeds ha -1 yielded 65% more than wide-row soybean at 455,000 seeds ha -1.
- Intervention effect Broadcast application of 23 kg N ha -1 urea increased the number of volunteer B. napus seeds produced by 77%.
- Recommendation Seeding soybean at increased densities with narrow-row spacing, and interrow tillage in wide-row systems, are effective strategies to augment chemical management of volunteer B. napus (authors recommendation).
