Grain yields in the high-rainfall zone (HRZ) have always posed a paradox, remaining far lower than modelling had predicted. However, that is now changing as a result of a comprehensive new research program covering farm-management practices, soil nutrition and plant biology and the development of tools that are helping to better predict the yield and economic benefits of applying inputs in the high-rainfall zone.Further information:Dr Penny Riffkin Dept.
