Response of Fenu-Greek (<i>Trigonella foenum-graecum</i> L.) to Rhizobium Inoculation

Response of Chickpea to Rhizobium Inoculation I. Nitrogen Fixation

Inoculation response of legumes in relation to the number and effectiveness of indigenous Rhizobium populations.

The response of legumes to inoculation with rhizobia can be affected by many factors. Little work has been undertaken to examine how indigenous populations or rhizobia affect this response. We conducted a series of inoculation trials in four Hawaiian soils with six legume species (Glycine max, Vigna unguiculata, Phaseolus lunatus, Leucaena leucocephala, Arachis hypogaea, and Phaseolus vulgaris)...

Early legume responses to inoculation with Rhizobium sp. NGR234.

Interactions between legumes and rhizobia are controlled by the sequential exchange of symbiotic signals. Two different techniques, 2D-PAGE electrophoresis and differential display were used to study the effects of rhizobial signals on legume development. Application of variously substituted lipo-oligo-saccharidic Nod-factors to roots of Vigna unguiculata resulted in changes in the phosphorylat...

L-tryptophan Application Enhances the Effectiveness of Rhizobium Inoculation for Improving Growth and Yield of Mungbean (vigna Radiata (l.) Wilczek)

Rhizobium inoculation has successfully been used for improving growth and yield of legume crops in different parts of the world. L-Tryptophan (L-TRP) application may further improve its effectiveness due to substrate-dependent inoculum-derived auxins in the rhizosphere. Rhizobium phaseoli strains were isolated using dilution plate technique from the mung bean nodules. Auxin biosynthesis by thes...

Growth effects of Rhizobium inoculation in some legume plants

Leguminous crops, possessing root nodules, fix and utilize atmospheric nitrogen. They are thus not dependent on industrially fixed nitrogen but add up to 30 kg of nitrogen / hectare to the soil and improve its fertility. Access to mineral nitrogen often limits plant growth, and so symbiotic relationships have evolved between plants and a variety of nitrogen-fixing organisms. These associations ...
