Abstract

The aim of this study was to lessen lodging in winter wheat by providing a guide to how factors affect lodging and by testing whether spring crop assessments could identify lodging-prone crops.

An aerial survey of 340 fields (2865 ha) in 1991-92, quantified the extent of lodging in a widespread lodging year. 91% of fields had some lodging, resulting in 16% area lodged. From these values it was estimated that a severe lodging year costs the UK wheat industry £60 million through yield loss and a further £60 million due to loss of bread making premium, grain drying costs and delayed harvest.

95% of lodged fields had lodging within the overlaps between the field margin and field centre, but only 2% had lodging immediately adjacent to the field tramlines. Regional differences in lodging were closely linked with soil type, rather than rainfall and wind speed, with most lodging on silt soils. The percent area lodged per field commonly varied from 10 - 90% within individual localities.
