Other claims from this paper (11)
- Observation Planting date contributed most to variation in soybean seed yield.
- Intervention effect Soybean seed yield in central Illinois decreased by an average of 33% as planting was delayed from early May to early July.
- Observation Seed yield of indeterminate soybean cultivars declined steadily after the early May planting date.
- Observation Seed yield of determinate soybean cultivars did not decrease until planting was delayed past early June.
- Observation Plant height and main stem node number of determinate soybean cultivars were greatest in early June plantings.
- Observation Lowest pod height of determinate soybean cultivars was less than 10 cm, close to the soil surface.
- Observation Seed yields of determinate and indeterminate soybean cultivars increased significantly as row width was narrowed from 80 to 50 cm.
- Observation Seed yields did not differ between 50 and 20 cm row widths.
- Observation Determinate soybean cultivar Elf performed well over plant densities of 279,000 to 494,000 plants/ha at harvest.
- Recommendation A seeding rate of 400,000 to 500,000 seeds/ha is sufficient to maximize seed yield of determinate soybean cultivars.
- Recommendation A seeding rate of 400,000 to 500,000 seeds/ha reduces potential harvest losses from low basal pod height and gives uniform stands.
