iOSR combines expertise from across the industry, with in-field science from Syngenta innovation centres and the practical experiences of a group of successful growers. Its aim is to deliver timely information and intelligence to enable more informed decisions for crop agronomy.
The challenges of growing oilseed rape are increasing, and agronomy techniques have changed significantly over the past five years.
Best results for oilseed rape performance can be achieved through crop management which minimises losses initiated by natural causes, and nurturing the crop’s potential by optimising its physiology and maximising energy capture. Read more of our latest insights below.
Georgina Wood - Syngenta OSR Technical Manager

iOSR Farmer Profiles
Chris Baylis, Head of Farming at Sir Richard Sutton Estates, manages around 850 hectares of oilseed rape among the 6,000ha of cropping across three farming units, from Lincolnshire down to Hampshire and Dorset. To establish the crop he uses a Vaderstad Rapid fitted with a Cultivation Solutions toolbar creating a combined strip till drill, the design incorporates a coulter either side of the cultivator tine, in a configuration that gives more of a band sowing effect and spreads the plant spacing, placement fertiliser is also applied across...
The Northamptonshire contract farming business of Greg Wilcox involves a wide range of establishment techniques and agronomy across 400 hectares of OSR. Strip till, direct drilling and Autocast will all be utilised where appropriate or available for the contract operation. In the right conditions, using the Autocast to spin seed and slug pellets into standing wheat has been extremely effective and kept the costs of production down, but he acknowledges it’s not for every situation and there is the severe limitation of not being able to used...
Joe Dilibero is the working Farm Manager for the 2,400 ha Berkshire unit of Sutton Estates, alongside his counterpart, Malcolm Vaughan, in Lincolnshire and the estates’ overall farms’ manager, Chris Baylis. Having joined the iOSR group when farming in Cambridgeshire, Joe brings a valuable practical insight into managing a diverse mixed-farm across a varying spectrum of difficult soils, from loam over gravel to heavy clay. Oilseed rape fits in the block-cropped arable rotation with wheat, barley and beans. Growing hybrid OSR varieties, they...
Chris Eglington farms 400 hectares near Dereham in Norfolk. With 13 soil types across the farm, predominantly medium to heavy loam, Chris precision drills his OSR at 56cm row width, with seven sub-soiler tines across a 4m working width. He sows just 21 seeds per m2 - the low rate required to get sufficient inter-row plant spacing, with volunteers typically filling in additional plants. Whilst yields have historically been good, he believes his four-year rotation has been too tight and, for the first time this year, has introduced peas to...
On the edge of the Lincolnshire Wolds, Oliver Smith manages 600 hectares for Stourton Estates, along with a further 200 ha of contract farming. This year he has 115 ha oilseed rape, which he reported is around 25% down on the area grown in the past. It will reduce the entry for first wheat, but does mean the rotational break for OSR will be extended. Oliver typically grows three OSR varieties a year, selected for proven consistency on the farm. It is established by strip till, using a Sumo DTS drill.
Heiko Lemburg achieved an average oilseed rape yield of 5.2 t/ha on his farm two kilometres from the Baltic Sea, in the Schleswig-Holstein region of northern Germany. A pioneer of conservation tillage, he reported similar problems of Flea Beetle to UK growers, and struggles with fertiliser input limitations. He also has a serious issue with Clubroot. But one key difference is that Blackgrass is still susceptible to sulfonylurea herbicides – which he’s making every effort to protect.
