The adaptation of high value pulse crops (chickpea, lentil and faba bean) is restricted by the suitability of current rhizobial strains to soil and climatic conditions. This project, in collaboration with similar projects in the GRDC's Northern and southern regions, will evaluate a range of elite rhizobial strains for high value pulse crops with the objective of releasing elite commercial strains. Such strains will improve the adaptation range of high value pulse crops and their use in farming systems resulting in increased nitrogen fixation and a reduction in reliance on inorganic nitrogen fertilisers.
