Abstracts |
A greenhouse experiment was conducted to study the effect of inoculation of soil (fine, kaolinite isohypothermic, Kanhaplustalfs) with a vesicular arbuscular mycorrhiza (VAM) fungus, Glomus mosseae, on selected tropical grain legumes such as, chickpea, cowpea, french bean [Phaseolus vulgaris], green gram [Vigna radiata], horse gram [Macrotyloma uniflorum], groundnut and pigeon pea at different soil solution P levels (0.01, 0.07 and 0.27 mg P/litre). Inoculation of soil with Glomus mosseae significantly increased the level of VAM colonization in roots of all plant species, but the extent of VAM colonization in roots decreased to 20% at soil solution P level of 0.27 mg P/litre and increased in soil solution P concentration at 0.01 and 0.07 mg P/litre. At the lowest level of soil solution P (0.01 mg P/litre), the extent of VAM colonization was more than 70% in chickpea, cowpea, groundnut and pigeon pea, while it was lowest (35%) in green gram. In french bean and horse gram, the VAM colonization level was 55 and 45%, respectively. VAM colonization in tropical grain legumes varied with plant species as well as different soil solution phosphorus levels. |
