OSR at a glance.

OSR can be a challenging and unpredictable crop to grow, from achieving good establishment, to overcoming disease, weed and pest pressure and then securing decent yields.

Despite this, it is still one of the most viable and profitable break crops, and the 2017 planted area increased to 600,000 ha.

What's really going on?

With the outlook for OSR seemingly positive, we wanted to know more about how farmers were making success of their crop, looking closer at the challenges they face.

What are the most popular variety types?

From farm saved seed to certified, open pollinated types to hybrids, there are a lot of options available when it comes to variety choice. Whilst individual varieties were not asked about, 43% are growing more than one type of variety.

Which of the following variety types are you growing this year (harvest 2018)?

What about cabbage stem flea beetle?

CSFB has been a major problem and over 70% have suffered from cabbage stem flea beetle in the last three years. However, pressure was thought to be lower this and good growing conditions helped many crops overcome attacks.

How would you rate the severity of CSFB pressure on your farm over the last three years?

Growers have tried a wide range of strategies to minimise the risk with varying degrees of success. 69% of growers are aware of the importance of good seedbeds and adequate soil moisture to support quick establishment. Higher seed rates, use of hybrid varieties and early drilling are all also popular strategies.

Have you tried any of these strategies to help minimise your CSFB risk and how successful have they been?

Protecting the crop.

Over the past three years, Sclerotinia has been the most frequently targeted disease with over 76% often applying treatment, with only 3% who don't apply anything.

How has OSR performed in recent years?

Crop failure was less prevalent this year (Feb 2018) and recent yields were considerably higher than the year before. 19% of growers suffered from some failed OSR crops this season with 3% of total winter OSR area lost. 27% of growers achieved yields over 4.5 t/ha.

Have you had any failed crops of winter OSR in the last three years, including this harvest year?

Do people understand winter OSR?

Out of a 1-5 score, 74% rated the agricultural industry’s understanding of winter wheat yield factors as a 4 or 5, compared to only 34% for winter oilseed rape. There's work to be done.
