Rapeseed yields at a low level in UK

Rapeseed yields are currently struggling in the UK, as the estimated average yield is only 2.6 – 3.0 t/ha, based on those fields that were taken to harvest. This is currently 14-26 % down on the 5-year average of 3.5 t/ha and a result of poor establishment, pest damage (cabbage stem flea beetle, pigeon, slugs)  and then poor over winter survival. About 70 – 75 Kha were already written off in May, but there are also some nice yield results with 4.7 t/ha when the establishment was good or later sown rapeseed was less affected by pests. Otherwise the yields dropped down to 0.5 t/ha.
