Abstract
Plant growth-promoting rhizobacteria (PGPR) improve plant growth and their application with suitable delivery matrix is an eco-friendly approach to sustainable agriculture. In the current study, Bacillus licheniformis ARS8, Bacillus marisflavi ARS23, and Pseudomonas fluorescens SS14 strains were investigated for their performance as liquid inoculum, coated seeds, and Enriched Soil-Based Fertilizer on wheat growth under climate room and field conditions. Both Bacillus strains ARS23 and ARS8 showed phosphate solubilization of 170 and 150 μg/ml, respectively, while Pseudomonas strain SS14 showed 23.54 μg/ml. SS14 also showed nitrogenase activity 199 nmol ethylene/h/ mg/protein. The maximum increase in root and shoot lengths and weight was recorded in treatments inoculated with Bacillus strain ARS8 and Pseudomonas strain SS14 in Enriched Soil-Based Fertilizer compared to liquid inoculum, coated seeds with [Bacterial strains + 1% (w/v) CMC] and control in pot experiments. A significant increase was noted in root and shoot lengths, weight, and yield in Bacillus strain ARS23 using enriched soil based followed by liquid inoculum and coated seeds inoculated treatments in both pot and field experiments. These results indicated that Bacillus spp. and Pseudomonas sp. using enriched soil as a carrier can be used as biofertilizers
