Isolation and characterization of bacteria from cocoa (Theobroma cacao) rhizospheric soils for different Plant Growth Promotion (PGP) activities / Aida Khalida Hamdan

Plant growth promoting rhizobacteria (PGPR) are a group of bacteria that can be found in the rhizosphere part which is near to the roots. PGPR could enhance the growth of plant through direct or indirect mechanism. However, there is no enough information on bacteria that can enhance the growth of co...
