Abstract:
|
Research on the effect of salinity on Rhizobium and its
symbiotic properties with legumes in the Sudan was reviewed. The review
indicated that (i) rhizobia are more salt tolerant than their host legumes;
(ii) the fast growing rhizobial strains are more salt tolerant than the slow
growing bradyrhizobia; (iii) salinity significantly reduces plant growth,
nodulation and nitrogen fixation; (iv) the response to Rhizobium
inoculation under saline conditions, with different soil textures, varies from
no response to a highly significant response; (v) under saline conditions,
application of N, P, S, mycorrhiza and chicken manure gives comparable
results to that of Rhizobium; and (vi) Rhizobium inoculation has a great
potential for improving fertility in saline soils. |
