Conteúdo:	How do windbreaks affect crop growth and yield and what are the economic consequences of windbreaks in cropping systems? A national project is providing some of the necessary base data and has developed a methodology suitable to answer this question. Progress has been made in gaining some understanding of windbreak effects through experimental work and also through the application and adaptation of models. To add credence to the current experimental and modelling work where some selected windbreaks are assessed in great detail, a regional survey was conducted for wheat grown on the southern Darling Downs in 1997. As part of this survey, the relative performance of wheat crops along transects behind existing windbreaks were assessed on one property on the Darling Downs. This showed that in 1997, wheat yield increases in the wake zone behind shelters protecting the crop from southerly and easterly winds were sufficient to elevate the normal yield decreases in the competition zone. Wheat crops growing behind windbreaks giving shelter to northerly or westerly winds had no beneficial impact.
