Abstract

Effects of Glomus fasciculatum and Rhizobium was observed on the growth, chlorophyll, nitrogen, phosphorus and potassium contents and on the root-rot disease complex of chickpea caused by Meloidogyne incognita and Macrophomina phaseolina. Application of G. fasciculatum and Rhizobium alone and in combination to plants with pathogens increased plant growth, pod number, chlorophyll, nitrogen, phosphorus and potassium contents and also reduced galling, multiplication of nematodes and root-rot index. Inoculation of Rhizobium caused greater reduction in galling and nematode multiplication than caused by G. fasciculatum. Inoculation of both the symbionts together were more beneficial for plant growth and reducing root-rot index than either of them. Pathogens had adverse effects on root colonization by G. fasciculatum. However, root colonization and root nodulation was increased when both symbionts were inoculated together both in the presence and absence of pathogens.
