Abstract
Many commercial oilseed rape crops, sown early, at high seed rate and with plentiful nitrogen fertilisation, have canopies that are too large. A series of experiments was conducted where canopy size was varied by sowing date (early or late September), seed rate (120 or 60 seeds m-2), nitrogen fertiliser (0 - 300 kg ha-1 N) and mowing. The dry matter and green area indices of leaf, stem and pod throughout development were determined by growth analysis and yield and yield components were measured. In 1998 and 1999, the potential for reducing pesticide and insecticide inputs to small canopies was assessed, with detailed records of pest and disease incidence and yield.
