A field experiment was carried out during 2014/2015 and 2015/2016 seasons at Sids research station, Bani Suef governorate, Agricultural Research Center (ARC), to evaluate the response of eight chickpea genotypes of a wide divergent origin were used; namely, seven introduced from IRCADA G1 (FLP0893C), G2 (S091013), G3 (S090642), G4 (FLP0846C), G5 (FLP0872), G6 (FLP0847C) and G7 (FLIP08-141C) and one local variety Giza195 (G8) cultivated under Egyptian soil conditions to bacterial applications as rhizobial inoculation alone or in combination with foliar application of pink-pigmented facultative methylotrophic bacteria (PPFMs), bacteria as The Plant Growth Promoting Rhizobacteria (PGPR) comparing with un-inoculated control fertilizered with 50kg N/fed. Results showed that, rhizobial inoculation in combination with foliar application with PPFMs bacteria produced the highest average chickpea seed yield per feddan (6.48 and 6.86 ardab) in both seasons, respectively, with no significant difference from rhizobial inoculation alone which produced 6.08 and 6.75 ard. fed.-1. Both bacterial treatments recorded the highest values of all studied traits. Concerning studied chickpea genotypes, Giza195 (G8) was the best in all studied characters with no significant difference from G3 (S090642) and G6 (FLP0847C). The highest chickpea seed yields were obtained from Giza195(7.75 and 8.15 ard. fed.-1) followed by G3 (7.08and 7.19 ard. fed.-1) and G7 (7.51 and 7.70 ard. fed.-1) under the combination of rhizobial inoculation and foliar application with PPFMs bacteria in both seasons, respectively. These results demonstrated the necessity of inoculation with specific rhizobial alone or in combination with PGPR bacteria to maximize growth and yield of chickpea genotypes.
