To determine the correct maturity timing required in lentils for successful crop-topping practice.
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.

TerminologyOnline Farm Trials: a web-based information system that provides open and free access to agricultural-based research trial data and information. OFT is a digital online resource managed through a collaboration between the Grains Research and Development Corporation (GRDC) and the Centre for eResearch and Digital Innovation (CeRDI) at Federation University Australia (FedUni).
Trial Contributor: an individual or organisation (e.g. grower group, research centre, commercial entity or government department) that makes data and/or other information available through OFT.
Metadata: information about Trial Projects submitted to OFT (e.g. names of the Trial Contributors, Trial Project title, Trial site location, Crop type(s), Growing season year(s), Trial type and Trial design). This data is compiled by OFT from information submitted with Trial Projects.
