Response of blackgram, chickpea and mungbean to vesicular arbuscular mycorrhizal inoculation in an unsterile soil
Response of blackgram, chickpea and mungbean to inoculation with the mycorrhizal fungus Glomus fasciculatum with and without added P (22 kg P ha-1) was studied in a P-deficient unsterile soil. Inoculation with G. fasciculatum increased the dry weight and P content of the shoot and root significantly over the uninoculated control. Application of P did not reduce the percentage root colonization by VA mycorrhizal fungi but increased the number of extramatrical chlamydospores in the soil. P application also increased the dry weight and P content of the inoculated plants, suggesting the need for application of P to obtain maximum benefit from VA mycorrhiza in P-fixing soils.
