Understanding and optimising weed suppression in intercrop systems

One of the major benefits of intercropping is its ability to decrease weeds. In this research, we aim to understand the mechanisms of weed suppression in different intercrop systems through a combination of field experiments and functional-structural plant modelling. We aim to understand why intercrops experience enhanced weed suppression and which traits are most responsible for this. Furthermore, we aim to understand how the design of the intercrop system influences its weed suppressive ability. Finally, through optimisation modelling we aim to combine this knowledge to find improved intercrop systems that have enhanced weed suppression and increased yield.
