Lodging - the facts
The impact of lodging in oilseed rape is often underestimated. Not only does it interfere with crop management and harvest, but more importantly it interferes with light penetration and so impacts adversely on yield.
- A field survey by BASF and ADAS in 2012 proved that on average 35% of oilseed rape cropping area lodged, often in the centre of the field.
- If the average lodged area of 35% were representative of the whole country, it is estimated that the lodging could have reduced the national average yield by between 0.25 and 0.61 t/ha (based on an assumed national average yield of 3.5 t/ha), resulting in losses of between £88/ha and £214/ha.
- Nationally this would mean a total loss to the UK oilseed rape industry between £56 million and £137 million.
