Bringing together the latest intelligence from across the industry to help oilseed rape growers make the most of early August drilling is an authoritative 20-page guide published this summer.
Produced jointly by leading crop production and establishment specialists, Bayer and Opico with experts from ADAS, NIAB and Wright Solutions, the new guide provides a wealth of practical advice for early drillers alongside the most important establishment essentials.
Sowing in the first two weeks of August has been invaluable in allowing many crops to survive cabbage stem flea beetle grazing in recent years, it observes. But moving drilling forward from its main mid-late August window brings with it a number of challenges that need to be addressed to make the most of this opportunity.
Chief amongst these is the danger of increased CSFB larval burdens in the spring. While reducing the pressure from phoma, earlier drilling is also recognised as adding to risks from light leaf spot, clubroot, and possibly also verticillium and turnip yellows virus.
At the same time, the guide points to the increased agronomic pressure presented by overly-large canopies susceptible to pre-mature stem extension in mild winters and serious damage from frost and snow if conditions turn cold.
Higher lodging risk is highlighted as a particular consideration too; especially where a combination of higher seed rates and better establishment results in dense stands of thinner-stemmed plants.
In addition, of course, sowing in early August means very little time from harvesting the previous crop, with obvious implications for previous cropping, straw management, grass weed control and correcting any soil structural problems. And machinery and workload issues at the peak of cereal harvest for most cannot been ignored either.
To make the most of the valuable opportunities earlier OSR drilling brings while avoiding its main pitfalls, the Guide to Early OSR Drilling identifies a number of important rotational, varietal, machinery and management priorities in a series of easy-to-read sections.
Foremost amongst these are:
“Making the new Guide available as widely as possible to growers and their advisers across the country this summer will, we very much hope, help them to take full advantage of the particularly good prospects for OSR in the coming season with the least risk,” comments Bayer OSR campaign manager, Lizzie Carr-Archer. “Copies can be obtained free-of-charge from both ourselves and Opico."
