The aim of this investigation was to study the effect of adding humic acid and plant growth promoting rhizobacteria (PGPR), as foliar and coating application on plant growth, nodulation status and yield of peanut under field conditions. Results indicate that, using microbial inoculation with Brady rhizobium as single inoculation and coinoculation with PGPR ( Azospirillum  sp.+ Bacillus polymyxa+ Serratia marcescens) as mixed inocul, conjugated with humic acid at two rates 3L/fed and 5L/fed. signicantly increased shoot dry weight, nodulation status and yield  of peanut plant under coating and foliar applications.  Incorporation of humic acid as foliar and coating application led to highest significant for all parameters above control. Also, coating application method was higher than foliar application. Shoot mineral content of N,P and K were increased by using coinoculation and addition of humic acid
