Partial male-sterile (ms(4)/ms(4)) soybeans (Glycine max L. Merr.) and their fertile isoline (Ms(4)/Ms(4)) were grown in adjoining field plots. From 62 until 92 days after emergence, the nitrogenase activity, assayed by acetylene reduction, of the average male-sterile plant was approximately twice that of the average fertile plant. At approximately 100 days after emergence, the assayable nitrog...
