Give up on the osr. Sorry. Wait until Feb for cereals. In the absence of pics. And I’m not an agronomist.

I haven’t got any OSR, but a friend posed the question to me. He is using Urea for the first time.
Somehow or other he always seems to have good OSR crops, but suggests it is absolutely plastered with larvae right now.
Based on my experience he’ll do well to get 2t/ha. Might be 0.

Last year, Harry as in the Harry’s Farm YouTube videos, got 12 tonnes off 110 acres.
He isn’t far away from me or the friend who asked me about Urea on OSR.
But Harry is on Cotswold Brash, rather than the liquorice all-sorts we both have.
@Two Tone if you want to stir the neighbours up, put some PK on!
It's too early for N. The risk of losing it is too high & there's not enough active growth to boost. N helps it grow. It doesn't make it grow. I'm with @Gong Farmer on this.

There you go @Cotswoldfarmer1977.
A bit like the two farmers growing potatoes one always followed the other if he went to plant potatoes the other followed straight away so he told his staf one spring to put the potato seed out in the field this was when they used to put seed potatoes out in the field in bags the staff said it's to soon he said it's ok so the bags were put in the field so the next door staff went and planted the first farmer went and brought his potatoes back in.

Yes, I wouldn't consider any urea applications before the second week of Feb, say. As Brisel says, any N only feeds growth that is happening, it doesn't stimulate growth that wouldn't otherwise be happening.
Same as PGRs and tillering, they support existing tillers, not create them.

I use TSum200 here.

It is somewhat location dependent. It could be something you consider for your location. I would say that if you are in area that has mild winters it could work.

The T-sum calculation is used to estimate spring N fertilization timing for perennial ryegrass. Beginning January 1, calculate the average daily air temperature measured in celsius. Fertilize for early spring or late winter growth when 200 "units" have accumulated. Calculate the average daily...

Is there a U.K. T sum map published anymore?I use TSum200 here.

Do you calculator your self or is the a website with regional dataI use TSum200 here.

Watch the daffodils. Well the main season varieties. Spread when begin to elongate stem. Will be mid february. Other old wives tales available - some with a lot of science in support!
No. In some mild winters it was achieved before the end of the NVZ closed spreading period, so gave mixed messages.
T Sum was designed for grassland which can start growing at lower soil temperatures than cereal crops.

Yes, the studies show that flowering daffs is time for AN, so urea when buds visible. Valentine's day. Dead cert. Always is.

Yes, sorry, thank you for correcting me, I should have been more specific with Urea at stem elongation before the 'pencil stage' and AN at flower buds opening. Goodness Tesla next thing you know I will be advocating variable rate N and using fancy sensing equipment - but I fear that is one step to far for a Laggard like me. Bit over 4 bags of Nitram to the acre. Bag to bag and half early, rest mid April, at your convenience. Speed up over the wet patches where not much crop - unfortunately these modern spreaders are too clever and adjust the rate if tractor slows or speeds up and only vary if there is some sort of software map in them. Think it is called progress. Bah humbug!! Best wishes,

Mine will get 200kg/ha bulk over the lot on or around valentine's day. Then will sit back, light my pipe and wait for the digestate to arrive. That way, should still be a margin if it's silaged due to blackgrass.
It's a little bit like realising that you may as well have just shut up and done what dad / grandad told you to do when you started.

In other countries they apply urea ontop of snow.
Anyone tried it here?
