Wasnt there trial work done showing In a very rapidly growing crop CCC doesn't have any effect on tillering. If your short head numbers and have your nitrogen out maybe even all at sowing your next beat option is to up the seeding rate.
Edit- what I'm trying to say is I don't think CCC has an effect in very fast growing crops and early nitrogen and seeding rate are the best control you have over tiller numbers

Welcome along Ant.
You have a similar rainfall as my part of the world.
I don't know what the ideal sowing date is where you are. 1st May would be too late here although it does happen if we have no choice.
I don't think there will be much yield difference between 150mm or 125mm row spacings, the plants will fill that extra space.
Plant numbers are important though as you seem to be aware. I would be aiming for 300-350/m2 for spring barley.
Your fertiliser input will depend completely on the levels of N, P & K in your particular soil, along with the usual pH requirements and trace elements.
In my experience, the main factors leading to a high yield of spring barley are (in no particular order):
I wouldn't want any more than 3 tillers per plant as the plant cant properly support more than 3 or 4.
CCC during tillering will increase tiller numbers but it will not increase yield.
Type of roller to use after planting? A Cambridge roller before crop emergence is my preferred option. I don't like rolling emerged barley but have done it - make sure the rings aren't too new and sharp.
I never bother counting grains on barley ears - the reason being two - fold 1. the grain number will depend on the ear population, a thinner crop will have more grains as it tries to compensate for lack of ears & 2. there is nothing I can do about the number of grains per ear.
Teagasc is our state run Agri Research body here. They published the Spring Barley Guide a few years ago - definitely worth a read: https://www.teagasc.ie/media/website/publications/2015/The-Spring-Barley-Guide.pdf

In my experience, the main factors leading to a high yield of spring barley are (in no particular order):
- Sown on time but not too early, spring barley needs to hit the ground running and not stop. The second half of march would be my ideal on free draining soil.
- Enough plants
- Nitrogen on early, finished (and hopefully washed in) by the end of tillering
- Top class seed bed (and I mean top class).
- Warm kind weather from emergence to tillering
- Cool bright weather from tillering to ripening
- The right variety
- Harvest as soon as it is ripe (an over ripe crop will lose a lot of yield by dropping specific weight and losing heads on the ground).
- Plenty of P in the soil (incorporate into the seed bed if P levels are below optimum).
- Good disease control (two spray timings in our climate).
- Break crops will increase spring barley yields above those of continuous spring barley.
- Tillering

Ccc needs to be early or forget about it
Counting seed/plants/heads is frowned upon

Any opinions on flat rollers? :Whistle2:

Don't forget making roads
Cabin fever has not set in and Bales V Pits has already started without the Flat V Ringrollers squaring up to each other.
2019 could be a rough year finishing up with a Yellow Jacket protest at the ploughing.

Did you say ploughing......? Down with such talk.
In the interests of inclusiveness in this modern society, I think "the ploughing" event should be renamed as "the cultivations".

It's okay I've seen The light, I'm now a ring roller Man too so one less To argue For flat rollers.
Now I just need To find a decent one!
Welcome along telesnag to F4F. The spring barley guide Cork mentions above Is definitely worth a read.
Ok i will try answer some questions and add more info, thank you for all the replies, very much appreciated!!!
1. Yes i do read the teagsc spring barley guide, its the best in the world i have found, trying to get the rubber to the road is the challenge.
2. Ccc not available, we are very limited with pgr in oz, we can get moddus. Straw is worth a fortune this year due to drought.
3. The crop will always grow like mad due to coastal enviroment, i think is part of the challenge with getting suffecient tillering, it will be fully out in head in 9 weeks and have heads poking out now in week 7.
4. Soil tests i will revisit, i cant remeber the numbers, i work in mining, doing 7 days on 7 days off, my brwin is cooked most of the time!! My work is 2500km away.
5. Done tiller counts yesterday and today, i have areas that will do 1000 heads i believe, areas below this are purely down on plants, i struggle with cockatoos eating seeds when sowing. Im a zon gas gun expert now!!
6. Becuase i am taking a sillage cut seeding earlier is hard work, i prefer to spread my risk and have this form of income rather than let paddock sit and go rank in wet.
7. I couldnt get planet seed, thats on cards for next year.
8. Normally with Westminster i would get 20_24 grains a head.
9. Due to pace of crop growth ive only ever got 1 fungicide on, net blotch is the only disease i get thus far. I sprayed crop today with radial, plus 15l ha of uan liquid n, 110 l ha of water. I reckon it will burn due to low due to low drift nozzles used by contractor, i hate them, i love the good old fashion flat fan mist, like god intended.
So far after the info i have recieved, i need to work on fertility, establishment (tricky) but a must.
I have to direct drill otherwise lose to much moisture, we have cool climate but springs can be drier than what i would imagine Ireland is?. I would never get on any earlier to sow due to wet dirt.
Rolling, i have a rubber tyre roller i can fill with water, due to crop establishment being uneven at times doing this effectively might be tricky but i really want to try this.
N application, since the growing is so quick i think? I am better to dump all on in one hit once drill rows are visible? I dont have my own spreader yet but will work on getting one.
Are tines or disc the preffered choice? I prefer tines to be honest, i have better tillering where the seed band is wide and not slotted in tight.
Some pictures post spraying today, the fungicide was oiler than i expected, i think it will burn, big droplet size didnt help.
See what happens?
Thanks for the info any help is appreciated....
Cheers, Ant...

Looks good to me!
Is rolling done best start of tillering, or if i have crop at different stages, whats the best middle ground??

Best done before seed germinates but ground needs to be very dry.

Yes they do. I’ve done it when it wasn’t dry enough at planting time.
As I mentioned earlier, I wouldn’t be rolling or using pgr to encourage tillering in spring barley unless I actually had a problem.
Damage will occur to plants from the tractor wheels.

To improve establishment roll straight after planting. To stimulate tillering roll just before tillering starts, damaging the main stem makes the plant think it's dying and puts out more tillers. The old school way was to graze with sheep which removed the main stem.
More so in winter barley not so much in spring barley.

My father was religious about rolling the emerged barley years ago. He always swore by it and I can't say I ever remember a crop lodging. How good the crops were though is another matter. I'd say 2 tonnes did a lot for them back then.

i try to roll mine at 3-4 leaf before tillering,heavy flat roll
im on red sandstone so quite light ground that needs to be firm
