To assess the agronomic practice of ‘crop topping’ at multiple application timings on grain yield and grain weight of lentil varieties varying in plant maturity.
Most varieties yielded did not incur yield loss from crop topping at the recommended timing indicating that they were well suited to crop topping at the recommended timing for rye grass control in 2014 where the season finished rapidly due to dry conditions.
As found in previous seasons there is not always a direct correlation between variety flowering and maturity timing and yield loss due to crop-topping.

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.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
Note that PBR cover is administered through the Plant Breeders’ Right Act 1994 (https://www.legislation.gov.au/Series/C2004A04783).
