Soybean response to inoculation and nitrogen application following long-term grass pasture
Current demand for soybean grain [Glycine max (L.) Merrill] may lead to a conversion of pasture and Conservation Reserve Program fields into soybean or corn (Zea mays L.) production. Our objective was to determine the effect of soybean seed inoculation with Bradyrhizobium spp. and fertilizer N application rate on soybean productivity planted 1 and 2 yr after conversion to row crop production. ...

Release of transgenic bacterial inoculants - rhizobia as a case study
The current debate on the release of genetically modified organisms to the environment must be informed by scientific data obtained from field studies. Many of the microorganisms that have potential applications outside the laboratory, especially in agriculture and horticulture, could be improved by genetic modification. Rhizobia, the bacteria that form N2-fixing symbioses with leguminous plants, ...

In-Furrow inoculation and selection for higher motility enhances the efficacy of bradyrhizobium japonicum nodulation
The issue of competition for nodulation has received much attention in studies on soybean [Glycine max (L.) Merr.] crops because native soil rhizobia often preclude nodulation of inoculated high-quality strains. In this work, soil placement and enhanced motility of Bradyrhizobium japonicum were investigated as strategies to improve the competitiveness of soybean inoculants applied in the presence ...

Nitrogen Fixers
Here’s a bit of geeky plant science. On this image of the roots of white clover, you can plainly see bumps along the roots that are called nodules. Over millions of years, the plant has evolved a symbiotic relationship with certain species of soil-dwelling bacteria called Rhizobia. This group of bacteria has the ability to take nitrogen from the atmosphere and “fix” it by ...

Water use by five warm-season legumes in the southern great plains
Growing warm-season legumes during fallow periods associated with traditional continuous systems of winter wheat (Triticum aestivum L.) in the southern Great Plains (SGP) can provide supplemental forage, biological N, and protection from soil erosion, provided the legumes can tolerate drought stress and not deplete the available water in the soil profile. Our objective was to quantify water use ...

Capabilities of four novel warm-season legumes in the southern great plains: Grain production and quality
Grain legumes could serve as a low cost nitrogen (N) and energy source for animal production in the southern Great Plains (SGP). This study evaluated the yield and nutritive value of grains of tropical annual legumes novel to the SGP. Included were cultivars of pigeon pea [Cajanus cajan (L.) Millsp.] (cv. GA-2), guar [Cyamopsis tetragonoloba (L.) Taub.] (cv. Kinman), cowpea [Vigna unguiculata ...
