Lodging in Rice

Lodging occurs when plant stems weaken to the point they can no longer support the weight of the grain causing it to fall over. As growers push for maximum grain yield, lodging is becoming a significant factor in rice production, increasing the time and cost of harvest and often resulting in significant yield loss.

Rice plant growth, particularly the stems’ ability to support the grain weight, varies depending on weather conditions that differ from year to year, so lodging will be worse in some seasons than others.
