Soybean nitrogen breakthrough could nearly double the production of soybeans and legumes

Soybean nitrogen breakthrough could nearly double the production of soybeans and legumes which make up 30% of the world’s crops

Washington State University biologist Mechthild Tegeder has developed a way to dramatically increase the yield and quality of soybeans.

Her greenhouse-grown soybean plants fix twice as much nitrogen from the atmosphere as their natural counterparts, grow larger and produce up to 36 percent more seeds.

Tegeder designed a novel way to increase the flow of nitrogen, an essential nutrient, from specialized bacteria in soybean root nodules to the seed-producing organs. She and Amanda Carter, a biological sciences graduate student, found the increased rate of nitrogen transport kicked the plants into overdrive.
