Why OSR ? Drummonds Seeds OSR Ad MPU 300 x 250

This year’s tillage harvest is well underway and many farmers have found huge variations in yield with one of the main differences being continuous versus first year cereal . In modern day farming high yields are paramount in order to sustain to profitability and that’s where OSR comes into play. The vast majority of crops have yielded between 1.5-2.1t/ac this year and with a market price of €370/t, it’s likely going to be the most profitable crop on Irish tillage farms this year.

oilseedOSR has lots of other benefits not only profitability.
On average OSR will increase yields by 0.75t/ac over continuous cereals. It also helps to control troublesome weeds such Sterile Brome / Black Grass and resistant weeds like chickweed and poppy. It also helps soil structure by breaking plough pans through its vigorous root system.

Another attribute to growing OSR is spreading the workload. OSR allows farmers to drill earlier and spread combining hours over a longer period of time.

osr Harvesting 3Agronomy

  • Soil – Ideal ph is between 6.5 to 7. If your ground is panned or suffers from compaction, a subsoiling should be considered before drilling
  • Fertiliser should be placed /spread before drilling to ensure a quick establishment
  • Target between 35/40 seeds per square meter when drilling in normal conditions at the right time. Increase the rate to 45 seeds in difficult conditions or if when drilling late.
  • The TGW is a vital tool when calibrating the drill
  • Aim to have a good soil to seed contact and also a fine and firm seedbed preferably rolled.
  • Herbicides - there’s plenty of good options when considering herbicide application but the first most important thing is field history. Does your field suffer from problematic weeds such Charlock, Vol Rape, Runch and Mustard ? If so Clearfield technology is the way to go.

 

Clearfield Varieties

  • It gives you the option to grow rape where Volunteer /weed Brassicas are a problem ie Charlock, Mustard, Vol Rape , Stubble Turnip and Runch
  • Flexible Post Em herbicide spray timing which ensures optimum crop establishment
  • Unaffected by establishment system
  • Rapid emergence

What is Clearfield Technology

  1. Clearfield Varieties have specific tolerance to Cleranda
  2. Cleranda is a co-form of imazamox + metazachlor
  3. Rate of use is 2l/ha + Dash 1l/ha. ( Dash is an adjuvant).
  4. Cleranda works best when applied to small, actively growing weeds
  5. Needs to be applied to a dry leaf
  6. Avoid rain after application
  7. Spray windows can be comprised if left to the end of October
  8. Reminder Cleranda is an ALS herbicide so if you know a field with resistant weeds, do not apply - ie poppy and chickweed. Clearfield varieties may not be of benefit in this circumstance.
