Bio-resource efficacy of compost and PGPR inoculation in improving sunflower plant growth and soil properties

Abstract

Biological origin of both compost and plant growth promoting rhizobacteria (PGPR) qualify them as bio-resource. They offer a unique role in preserving and balancing the integrity of the ecosystem. Effectiveness of these bio-resources clearly showed marked improvement in plant growth, yield and qualitatative attributes of sunflower as well as soil properties too in a pot experiment. The results of this study proved that organic waste can be managed through a meaningful approach of composting and further, integrating with rhizobacterial inoculation can benefit both soil and plant environment.
