Later drilling is often a difficult concept for growers to embrace fully. Memories of sluggishly developing crops and cold, wet autumns still sit firm in the minds of many growers. But it’s a very scenario now with significant breeding work gone in to the best varieties to ensure they can establish quickly in a range of growing scenarios including the freezing conditions of Eastern Europe.
Research has show that over 70% of the total root mass of oilseed rape is developed in the first 45 days weeks after sowing – hence Incentive 45’s name.

Trials being carried out in the UK and Germany are showing how new hybrid genetics can help oilseed rape crops bounce back after severe pest attack early in the growth cycle, says DSV UK’s Michael Farr.
Verticillium wilt has been the focus of much breeding development in Germany in recent times following a steady rise in the disease’s incidence over the last 20 years, says Dr. Alex Doering of seed breeders DSV.
Although not a disease criteria identified on current HGCA Recommended Lists, choosing oilseed rape varieties with proven tolerance to verticillium wilt could be a good idea for UK growers if the recent experience in mainland Europe is anything to go by, says Dr. Alex Doering of seed breeders DSV.
It’s not just a question of choosing a ‘high vigour’ variety to help protect against potential losses from pests and diseases without neonicotinoids, says Mike Mann of DSV UK.
New trials focusing on how oilseed rape roots develop is giving seed breeders DSV fresh insight into how stronger and more tolerant varieties can be developed in the future.
Trials by Suffolk-based agricultural consultancy group Agrivice Ltd have focused on verticillium wilt tolerance in close rotations and confirm the need for strong early growth and primary root development.
Choosing the right variety to match individual conditions and drilling dates can have a major impact on the subsequent management of oilseed rape crops and the gross margins achieved.
The carefully selected variety of plant species in DSV’s TerraLife range of cover crop mixes is an essential part of their function but adds no additional complexity of management over single variety cover crops, says the company’s Emma Bedford.
If you’re thinking about growing cover crops you need to focus on what you expect to achieve and invest in the crop sufficiently to deliver it, believes one Oxfordshire arable grower.
With oilseed rape now starting to grow away you can learn a lot about it’s harvest potential by considering what your crop has looked like in recent weeks, says Sarah Hawthorne of DSV.

With all his oilseed rape down to the new DSV variety Incentive this year, Suffolk grower Ali Drummond says the variety’s early vigour is a key element of his strategy for life with neonicotinoids.
“I don’t want to compromise on yield and oil content but the more agronomic properties a variety has built in the more relevant I think it will be in type of farming we will be doing in the future.
With DSV variety Compass always doing well on his heavy land and the need for a rapidly establishing variety to counter potential early disease and pest threats, Incentive was the by far the best choice says Cheshire grower Robert Cross.
Warwickshire grower Stephen Cowper’s Incentive oilseed rape not only ‘shot out of the ground’ after drilling its rapid subsequent growth has helped it shrug off all pest and disease attack.
Although concerned about managing the early weeks of growth following the loss of neonicotinoids, the variety’s early establishment has created the perfect crop going into winter, he says.
Incentive’s noticeably quicker establishment than other oilseed rape varieties has helped it growth through all early pest attacks at Nick Abraham’s High House Farm, near Dereham in Norfolk.
“We drilled another well known hybrid variety 10 days earlier that our Incentive and it had overtaken it within 3 weeks,” Nick explains.
Oilseed rape growers should avoid drilling early this year to avoid serious pest and disease problems, warns ADAS plant specialist Pete Berry. Whilst the early harvest and loss of neonicotinoids is tempting many producers to start drilling in the next few days, record numbers of flea beetles, perfect conditions for virus transmission and the prospect of unmanageable canopies late could make this a disaster.
With a harvest of mixed fortunes behind them, East Anglian oilseed rape growers face 2015 with some important lessons learned, believes Sarah Lockhart of Downham Market-based DSV UK Ltd.
Although only confirmed in the UK in 2007, this year has seen verticillium wilt spread rapidly across the country from its South East origins. Varietal choice plays a large part in limiting the effects of the disease, but some claims of resistance are misleading, says DSV’s Sarah Lockhart.
Strong early establishment and root development is one of the main reasons some oilseed rape varieties tolerate verticillium wilt attack better than others, says Sarah Lockhart of DSV UK.

Incentive is the most exciting new hybrid variety to top both the North Region and East and West Region HGCA recommended lists in a very a very long time. It offers growers enormous potential with strong hybrid traits.
Nearly half of Lincolnshire producer Andrew Pearce’s oilseed rape acreage is the new DSV variety Incentive this year following two difficult seasons struggling with various establishment and lodging issues with other varieties.
“The fact that Incentive has topped both the East/West and Northern regions of the HGCA Recommended Lists proves what a great combination of high performance and versatility the variety has. "
Incentive is a significant step forward in terms of performance and versatility over the main oilseed rape varieties that have been at the top of the HGCA lists for the last few years.
With the highest gross output on the 2014/15 HGCA Recommended List, Incentive 45 is not only a true all-round performer.
Incentive 45, named for its very early and vigorous growth in the first six weeks, was best in the East/West and Northern region of the Home-Grown Cereal Authority’s Recommended List.
With the highest gross output on the 2014/15 HGCA Recommended List, Incentive 45 is not only a true all-round performer, its rapid early establishment also gives it several agronomic advantages, says DSV UK Managing Director Mike Mann.
