It is highly adaptable to different edaphoclimatic conditions, being an important crop in addressing global food security challenges. The common bean production segment has undergone an intense technological advance, with a focus on the use of technologies to increase the availabilityofnitrogen(N)andthecrops’ seedyield,whileenhancingeconomicandecologicalsustainability.Basedonthis,the present meta-analysis aimed to evaluate the effects of Rhizobium inoculation (RI), in comparison with mineral-N fertilization (NF), on the main nodulation characteristics, yield components, and seed yield of common beans. This study represents the largest assessment yet on this topic. We used data from peer-reviewed publications and, after extensive bibliographic research, analyzed68studiesfromsevencountries.WefoundthatRIincreasedseedyield(32.96%)butnottothesameextentasNF.The RIisonaverage12.31%lessefficientthanNF;however,whenwecategorizedthefactors,suchasthetimeofyearwhencommon beans were grown, the soil management system, and the soil physicochemical characteristics, the RI effects were more promising.Hereweshowfor thefirst timethatRI wasmoreefficient thanNFwhencommonbeans werecultivatedinthedryseason, under a no-tillagesystem, and in soils withhighorganic mattercontent,with a potentiallypositiveimpactonyields.
