Abstract
A Pot experiment was conducted in wire house to study the effect of coinoculation with Rhizobium and two plant growth promoting rhizobacterial (PGPR) strains (Q7 & Q14) on mungbean (Vigna radiata L.). The Rhizobium, Q7 and Q14 showed better results over uninoculated control whether inoculated alone or in combination with each other. The coinoculation of Q7 and Q14 with Rhizobium showed better results over Rhizobium alone. PGPR Q7+ Rhizobium increased plant height, root length, number of nodules and number of grains pod" by 10.8, 5.5, 56.5 and 37.7%, respectively, over Rhizobium alone, while PGPR Q14 + Rhizobium decreased these parameters but increased number of pods ptant', 100 grain weight and number of grains plant" by 66.1, 43.1 & 68.6%, respectively, compared with Rhizobium alone. Q7 strain promoted vegetative growth but grain size was less as compared to other treatments while Q14 strain showed bold grain size and more yield Key words: Coinoculation, plant growth promoting rhizobacteria, rhizobium, mungbean
