It is both amusing and instructive that Fred and Graul began their 1916 paper with the
following words:" It has been known for a long time that the presence of certain salts in the …

Symbiotic nitrogen (N2) fixation in legumes may give the host plant a distinct competitive
advantage; at the same time it is mainly responsible for introducing N into terrestrial …

Nodulation and nitrogen fixation by legumes is adversely affected by higher doses of
fertilizer N. Fertilizer N. especially nitrate, affects nodulation mainly by destroying indole …

Soil fertility requirements of cool season grain legumes are reviewed. Nitrogen commonly
limits plant growth but inoculation with an appropriate strain of Rhizohium can alleviate most …

activity (NiRA) from roots and nodules of 5 mutant genotypes and one commercial cultivar …

A rhizosphere application of NO inf3 sup-and/or naringenin affected the Pisum sativum—
Rhizobium leguminosarum biovar viciae symbiosis. NO inf3 sup-(5 m M) lowered while …

The relative effect of increasing external nitrate supply on the nodulation of 3 winter crop
legumes was examined in a controlled environment experiment. Lupin (Lupinus …

Bacteroidal and cytosolic fractions of nodules of pigeon pea plants (inoculated with
Rhizobium PP-11) contained a constitutive nitrate reductase which functioned with NADH …

Legumes have a tap root with lateral branches, but there is substantial genetic variation in
root characters. The proportion of total plant dry weight found in the root systems of most …

Levels of nitrogenase, hydrogenase, 02 uptake, and some enzymes of C02 assimilation, viz.
