“…Azotobacter chroococcum decreased in number around tomato roots more slowly if they were mycorrhizal (Bagyaraj and Menge, 1978). Inoculation of crops with mycorrhizal fungi and Rhizobium was found to have a synergistic beneficial effect on nodulation, nitrogen fixation, mineral uptake and plant growth (Daft and El-Giahmi, 1976;Bagyaraj, Manjunath and Patil, 1978).…”

INTERACTION Between A VESICULAR–ARBUSCULAR MYCORRHIZAL FUNGUS AND STREPTOMYCES CINNAMOMEOUS AND THEIR EFFECTS ON FINGER MILLET

SUMMARYGrowth and phosphorus nutrition of finger millet (Eleusine coracana) on a sterile, phosphorusdeficient soil was improved by inoculation with either the vesicular-arbuscular mycorrhizal fungus Glomus fasciculatus or with the streptomycete Streptomyces dnnamomeous. These micro-organisms interacted antagonistically when added simultaneously or with one 2 weeks after the other: Streptomyces reduced spore production and development of infection by Glomus, while Glomus reduced the multiplication of Streptomyces. Because of this antagonism, dual inoculations stimulated plant growth less than individual inoculations.

“…Inoculation of soybean with plant growth promoting rhizobacteria Serratia liquefaciens or Serratia proteomaculans hastened the onset of nodulation in cool season, total fixed N, Ndfa and protein yield [84]. PGPR inoculation was thought to be most effective for those cultivars which have a higher yield potential.Co-inoculation of AMF (Glomus fasciculatum) along with rhizobia significantly improved nodulation, BNF, shoot N and P content and yield of soybean [85][86].

Advances have included discovery of alternative nitrogenases, elucidation of more details on the mechanism of action, discovery of novel nitrogenases, existence of nitrogenase siblings in eukaryotes etc. There are fresh efforts to engineer cereal plants to nodulate and fix nitrogen. Discovery of common signalling mechanisms between mycorrhization and nodulation, discovery of cereal endophytes and advances in plastid physiology have given a f r e s h i m p e t u s t o s u c h a p p r o a c h e s .

Advances in molecular biology have included a greater understanding of the native diversity of rhizobia and together with advances in plant breeding for selection of high nodulating genotypes, presents an attractive opportunity to maximize BNF. Recent advances include the discovery of novel rhizobial species, emphasis on study of climate change and adaptation to various abiotic stresses like high temperature, drought and salinity.

“…AM (Arbuscular Mycorrhizal) Fungi, are found to be associated with a number of leguminous crop plants (Bagyaraj et al, 1979;Tilak et al, 1987; Vijay kumar and Bhiravamurthy, 1999) and beneficial effects of these fungi in phosphate uptake have been reported by different workers (Islam and Ayaneba, 1980;Reinhard et al, 1994 andRajeshwari et al, 2001). Most of the work has been focused on phosphate nutrition, because 'P' is one of the major plant nutrients.…”

Abstract:The pot experiments were undertaken to study the relative efficiency of dominant AM Fungi (Glomus fasciculatum and Glomus heterosporum) recovered from natural undisturbed saline belt of Purna river sub basin. The pure inoculum of these species were treated individually and as a mixed inocula in combination with phosphoric fertilizers supplied as 25, 50, 75 and 100% (mg/kg P 2 O 5 /ha). The influence of AMF inoculation in different levels of 'P' fertilizer on% colonization, MIE % and P-uptake were calculated. Plevel of 75% was found to be better in compare to 100% and can be recommended as phosphoric dose for soybean plants.
