OSR rate for Campus off the heap

[Tompkins]

Slightly off topic but of the newer conventional varieties, what would people recommend for this year and farm saving for a few years after that??

Its interesting if the UK is getting new conventional varieties coming through. We have had nothing new available independently tested in France since 2014. The last is called ES Mambo and I believe the most widely grown variety in France.

I don't know if this is because the breeders are not entering anything for trials or because the gov agencies responsible are pushing hybrids for our own good.
Newer conventional varieties are imported from other EU countries but without testing they are a shot in the dark for us.

I’ve gone with Acacia for half my OSR area this year, the other half being hybrid but like you, I’m hoping to FSS next year

Some home saved seed coming up already.

Count out 250 seeds, weigh them x4 = TGW you say good germ from your test so work on 95%, target population 45 plants, allow 10% field loss. With a TGW of 8g (bold sample you say) works out to 4.2kg/ha. Why are we disregarding years of trials that say 25-35 plants coming out of winter produces optimum yield? I appreciate we've lost seed dressing insecticides. Just thinking of a number doubling it for good measure and adding some more because it's cheap off the pile is senceless. Good seedbed, moisture, and planting this early = 40-50 seeds per m2. Only my opinion though.

This year the stuff that looked thin and crap until the spring has outyielded the 'thick' stuff considerably. Also made the mistake of assuming that Matrix Clearfield were 3ha packs at 50seeds/m2 like nearly all other rape - wrong, it is 60 seeds. Realised on the final field which was reduced to 50 seeds and yielded 0.5t/ha more than the others.

2%

Edited to add: I think the tolerance at the crush is 4% but I wouldn't want to be breeding up anything over 1% @crazy_bull ?

Not sure I would want to drill anything with a reading above zero in erucic acid for seed, and if you keep getting readable levels consider growing clearfield varieties with corresponding spray to kill off the volunteer issue.

contractual spec is 2% but homes generally only kick off if it tests above 5%.

interestingly the breeders of Mambo have just launched a candidate variety called Pinacle that looks a fair shout at a new conventional.

if anyone wants any to try drop me a DM

Drilled 20th July
6kg/Ha seed, 15kg/Ha N in the row. One dose slug pellets broadcast. Graminicide a few days ago.

What are the row spacings there?

 

[snarling bee]

600mm
Cousins 6m Oil Drill with 10 micro wing legs.
Want to keep as much as possible undisturbed for the Kerb to work well on any blackgrass that grows.
Row width will be fine I think at this early drill date unless there is a blocked spout anywhere which will mean a 1200 spacing!!
