Lodging in rice locations
Aims

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 andreduced grain quality.
Several factors influence lodging susceptibility including seasonal weather, variety, sowing method, nitrogen rate and timing, plant density, water depth, time of draining and wind or rain as the crop nears maturity. Some of these factors can be managed, thus providing the opportunity to reduce crop lodging potential.

Key messages

• Lodging is becoming a significant problem in rice as growers push for maximum grain yields, but some varieties are more prone to lodging than others.

• Management practices such as drill sowing, reduced sowing rate, reduced pre-permanent water nitrogen rate and draining on time reduce the potential for lodging.
