Abstract:
In this study the ability of Pseudomonas fluorescens FPD-15 to promote plant growth was assessed under greenhouse conditions using JL-24 variety of peanut as a test crop. A pot experiment was carried out in completely randomized factorial design with two main factors to investigate the effect of application of Pseudomonas fluorescens FPD-15 with Bradyrhizobium strains NC-92 and SSP-24 under preincubated and coinoculated conditions (as a main factor with seven levels) at different time intervals (as the second main factor with three levels) with 3 replicates. Analysis of Variance (ANOVA) on each measured response variable (comprising root and shoot biomass, nodule number and dry weight and nitrogen content) was performed using the GLM procedure of SAS. The inoculation of peanut seeds with FPD-15 significantly increased root and shoot dry weight, nodule number and dry weight and N content in shoot when compared to the control. The interaction between FPD-15 and Bradyrhizobium strains NC-92 and SSP-24 were studied under preincubated and coinoculated conditions. The preincubated treatments yielded significantly higher root and shoot dry weight, nodule number, nodule dry weight and percent N content of shoot compared to the coinoculated treatments. Field trials using these strains should be conducted before they can be exploited in a commercial set up.
