To investigate how nutrition can help mitigate waterlogging losses in wheat, canol and faba beans after a wet winter
Despite presenting with some waterlogging symptoms, faba beans and canola yielded exceptionally well. It is critical to understand the crop growth stage during waterlogging to determine potential yield impacts.
• Nutritional products applied did not influence grain yield except for the trial at Hagley, Tasmania, where a yield response was observed with different rates of nitrogen applied.
• Established plants will be most affected when they are rapidly growing, for example prolonged waterlogging during the warmer spring period is where yield penalties will be most severe.
