Abstract: To explore the effect of PGPR for improvement in grain yield of mungbean, different levels of fertilizer (00:00, 20:50 and 20:70 kg N:P2O5 kg ha-1) were tested on four strains (CB 1015 Australia, Vm-L1, Vm-M1 and Vm-M2) at Agricultural Research Institute, Dera Ismail Khan. A Randomized Complete Block Design with split plot arrangement was used to conduct the experiment by keeping three fertilizer levels in the main plot and Rhizobium strains in sub-plot. The data were recorded for different parameters like number of branches plant-1, number of clusters plant -1, number of pods plant-1., number of grain pod-1, pod length (cm) and grain yield kg ha-1. The response of fertilizer levels and inoculation with Rhizobium strains were found significant in most of the parameters under study. The strain Vm-M1 produced the highest number of branches plant-1 (5.42), number of clusters plant-1 (22.92), number of pods plant-1 (77.64), pod length (8.37 cm) when applied in combination of N:P2O5 @ 20:70 and 20:50 kg ha-1. Although the grain yield (1421 kg ha-1) recorded in treatment (20:70 kg N:P2O5 ha-1 + Inoculation with strain Vm M1) was highest but economically the treatment (20:50 kg N:P2O5 ha-1+Inoculation with strain Vm M1) with net return of Rs. 13618 ha-1and BCR of 2.52 was on top.
Key word: Mungbean, Rhizobium strains, Grain yield, Economic analysis, BCR.
