Response of Arbuscular mycorrhizal fungi and Rhizobium inoculation on growth and chlorophyll content of Vigna unguiculata (L) Walp Var. Pusa 151

R Arumugam, S Rajasekaran, SM Nagarajan


The aim of the present study was to investigate the effect ofRhizobium and Arbuscular mycorrhizal fungi inoculation, both individually and in combination on growth and chlorophyll content of economically important plant Vigna unguiculata L. A significant (p < 0.05) increase over control in root length (45.6  cm), shoot height (12.2 cm), dry weight of root (0.4 g) and shoot (1.8 g), total number of nodules (39.6 nos.), dry weight of nodules (0.5 g), percentage of mycorrhizal infection (96.6 %), chlorophylls a (0.83 mg/g fr.wt.), b (1.19 mg/g fr.wt) and total chlorophyll (2.24 mg/g fr.wt) was recorded in dual inoculated (AM fungi and Rhizobium) plants than plants with individual inoculation. Thus it is  clear that the dual inoculation with AM Rhizobium biofertilizer is more effective than the individual treatment. @JASEM
