Reasons Why High Planting Density Dose Not Increase the Yield of Soybean Cultivar ‘Sachiyutaka’ in Nara Prefecture and Yamaguchi Prefecture, Japan

Field studies were conducted in 2011 and 2017 in Nara and Yamaguchi prefectures in Western Japan to examine why the yield of the determinate soybean cultivar ‘Sachiyutaka’ is not improved by increasing the planting density. Branching, radiation interception (IR), radiation use efficiency (RUE), and...

Zusammenfassung:Field studies were conducted in 2011 and 2017 in Nara and Yamaguchi prefectures in Western Japan to examine why the yield of the determinate soybean cultivar ‘Sachiyutaka’ is not improved by increasing the planting density. Branching, radiation interception (IR), radiation use efficiency (RUE), and dry matter production were evaluated in ‘Sachiyutaka’ planted at normal (
