The use of potent and effective live microbial biofertilisers in agricultural has significant
potential to reduce the costs of crop production and in mitigating greenhouse gas emissions
and water pollution associated with excessive fertiliser use. Many plant associated
bacteria possess plant growth promotion traits. However, when used as plant inoculants
these bacteria often do not result in statistically significant plant growth promotion. This
paper describes the screening process used to identify a number of endophytic strains
with multiple plant growth promotion traits and effective plant colonisation ability in
Brassica napus crops.
