Abstract
This research was carried out to evaluate the effects of single and combined inoculation with plant growth-promoting rhizobacteria from four genera including Azospirillum, Azotobacter, Mesorhizobium and Pseudomonas on nutrient uptake, growth and yield of chickpea plants under field conditions. Nodulation and nutrient concentration in shoots were significantly affected by the treatments at the beginning of flowering stage. The maximum dry weight of root nodules was recorded by applying the combined inoculation with Azospirillum spp. + Azotobacter chroococcum 5 + Mesorhizobium ciceri SWRI7 + Pseudomonas fluorescens P21. All inoculants were statistically superior over uninoculated control with respect to nitrogen concentration of shoots. The treatments containing Azospirillum + Azotobacter significantly improved phosphorus concentration in shoots. Grain yield, biomass dry weight and nitrogen & phosphorus uptake of grains were statistically improved by applying every inoculation treatment in comparison with control plants. Group comparisons between treatments showed that the occurance of Azospirillum or Azotobacter inoculants in the treatment composition caused an expressive improvement in grain yield and plant biomass. In conclusion, application of every inoculation treatment studied here, especially treatments which contained Azospirillum or Azotobacter may stimulate growth and yield of chickpea as compared with uninoculated plants.
