To determine the correct maturity timing required in lentils for successful crop-topping practice.
Key messages
There was a strong crop-top timing response, but limited variation between varieties from crop-topping in 2012. This may be due to below average end-season rainfall, suppressing some yield potential of untreated plots, particularly in later maturing varieties.
All varieties showed yield loss from crop-topping two weeks prior to the recommended timing. A link between plant maturity and reduced yield was observed at the Early crop topping timing, with earlier maturing varieties showing the least effect and later maturing varieties presenting the greatest effect. At the Recommended timing only two of the later maturing varieties showed any yield loss.
