Rhizosphere Effects: An Evaluation

This paper deals with the concept and effects of rhizosphere zone and the microorganism found around the roots of plants. The micro organism are of very high importance for plant growth. However, some of them exert negative effects also on the growth of the plants. The conditions affecting rhizosphere region are also highlighted in the paper. The deleterious rhizosphere microorganisms (DRMO) affecting plant growth (fungi & bacteria) are especially mentioned in the paper. Besides, modes of growth promotion activities of PGPF and antagonism between soil micro organisms and their impact on plant pathogens are also thoroughly reviewed and discussed in the light of empirical results.
