Abstracts |
A pot culture experiment was conducted using sterile, phosphorus deficient soil to study the effect of fly ash at 3 different concentrations (10, 20 and 30 g fly ash/kg soil) on the infectivity and effectiveness of vesicular arbuscular mycorrhiza (VAM) fungus Glomus aggregatum in pigeon pea (Cajanus cajan cv. Maruti). Fly ash, applied in all 3 different concentrations, was found to significantly affect the intensity of VAM fungal colonization inside the plant roots and also suppressed the formation of VAM fungal structure (vesicles and arbuscules) completely at higher concentration (30 g fly ash/kg soil). The response of the pigeon pea plants, in terms of dry weight, under the influence of fly ash amendment in VAM fungus infested soils was found to be considerably less (though not significant enough) when compared to the control plants (without fly ash) that have otherwise shown significant increase in growth over the plants without G. aggregatum inoculation. However, fly ash amendment without VAM inoculation was also found to enhance the growth of plants as compared to control plants (without fly ash and VAM inoculum). |
