CSFB larvae for the chop

Product Update

New trials on the iOSR Focus Site are looking at flailing off leaf petioles to physically remove CSFB larvae and break the insect pest cycle.

Spring clean for OSR leaves over winter

Product Update

Oilseed rape crops have, for the most part, come out of the winter remarkably clean of disease - especially given the early intense Phoma pressure that was well controlled.

iOSR Farmer Profiles

Chris Baylis

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...

John Haynes

John Haynes has 300 hectares of oilseed rape among the 1,200 ha he manages for MJ & SC Collins based on the Hertfordshire/Essex border. The area is down this year, with the introduction of beans into the rotation, and damage loss from sustained Flea Beetle attacks. In recent seasons establishment has been with a Vaderstad Top Down, allied to a press and rolls to conserve moisture, reduce Flea Beetle damage and to improve herbicide performance. John is now also looking at how the farm’s Horsch Sprinter may be utilised for OSR sowing in...

Greg Wilcox

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

Joe Dilibero

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

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...

Oliver Smith

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.

Philip Bradshaw

Cambridgeshire grower, Philip Bradshaw, has pioneered various establishment techniques and variety trials, including the use of a Sly Stripcat to establish OSR and mustard crops, with strip cultivation at 60 cm rows. Farming as part of a group of growers, they have around 1020 hectares of OSR. Phil aims for a four-year rotation, but will readily adjust the area to only crop where he believes they can achieve profitable yields. The farm averages yields of 4.7 t/ha, with the best performing crop from a stand of just 146 plants per m2 – so he...
