Studies on the effect of biofertilizer comprising of the plant growth promoting rhizobacterial Pseudomonas fluorescence strains on leguminous and non leguminous plants height at different soil pH

Soil fertility improvement is an important area which needs attention since most of the hazardous inputs added into the forestry system are in the form of chemicals. Since plant growth and soil normal flora are affected by input of chemical fertilizer. Bio-fertilizer microorganisms make the nutrients available to plants. The present study was concerning to isolate of Pseudomonas fluorescence species that possess a promising properties which make it a better bio-fertilizer bacteria. Pseudomonas fluorescence species was isolated from rhizospheric soil of Dalbergia sissoo and Solanum tuberosum tested for soil fertility and plant growth .Pseudomonas fluorescence directly inoculated with the soil pH and showed the increased plant height. Pseudomonas fluorescence enhances the growth and role of the plant growth promoting rhizobacteria. The concluded that plant growth promoting rhizobacteria (PGPR) can be used as a good tool in the enhancement of plant height and alkaloid contents in medicinal plants and other plants. As result, all tested isolates of Pseudomonas fluorescence have given strength to soil and increased plant height. So it could be summarized that all Pseudomonas fluorescence isolated strains can be used as bio-fertilizers for soil fertility improvement.
