Intervention effect Intercropping and microbial inoculation significantly affected all measured traits in Moldavian balm and common bean.
Intervention effect Combined AMF and PGPR treatment produced the highest growth indices in bean and Moldavian balm intercropping.
Intervention effect Bean seed yield was highest in sole cropping at 3.20 g and lowest in 1:1 intercropping at 1.57 g.
Intervention effect Bean biomass yield was highest in sole cropping at 9.70 g and lowest in 1:1 intercropping at 4.41 g.
Intervention effect Moldavian balm biomass yield and other traits were maximal in sole cropping.
Intervention effect Moldavian balm essential oil percentage was higher in all intercropping patterns than in sole cropping.
Observation Geranyl acetate, Geranial, Geraniol and Neral were the main constituents of Moldavian balm essential oil.
Intervention effect The highest land equivalent ratio, 1.67, occurred under 2:2 intercropping with PGPR inoculation.
Intervention effect Sole cropping produced higher plant growth indices than intercropping for Moldavian balm and bean.
Intervention effect Microbial inoculation in intercropping was associated with higher land equivalent ratio.
Recommendation The authors recommend intercropping with combined AMF and PGPR to improve yield and yield components.
