DD barley

[SilliamWhale]

Anyone got any really good dd barley?

If so how did you do it?

Winter or Spring?

Have some lovely winter put in with Claydon. Spring is looking OK, but not 100% happy with it.

 

[SilliamWhale]

I meant Spring.

Been round with agronomist on SB today. Tillered badly and looking spindly. Just cannot put my finger on why its not done much. Nor can she really. Its definitely not compaction and shouldn't be lack of any particular nutrients.

Obviously the cold and wind. I guess the cold may have scuppered any P availability that tillage would have done.

Bit of a shame as thin spring barley can't sort itself out.

Why do you say that?

Why do you say that?

Soil test looks ok. Field history and past cropping etc. Has P, K, Ca and N. Not actually done a tissue test on it but on other fields tissue testing hasn't come up with much this year.

Why do you ask?

I thought you posted a tissue test this year with quite low nutrient levels.

Only asked because I wanted to know what you'd done come to that conclusion.

Cold has certainly hit it here, there was a very hard cold week in early April that upset some of the earlier sown crops, later swon looks a little better as it got away a bit better and tillered more evenly.

I posted a wheat one where everything was quite good early on and then did one after which showed lower in Mg but not massively. Soil tests show a good mg/ca relationship

Actually having had a look at it again maybe it is pointing to lower Mg that Wheat isn't bothered about but Barley may be? Also though I recently put on Ca lime, that can affect the Mg status maybe?

The reading I've done recently suggests that wheat responds better to Mg than barley.

We had some winter wheat planted at the beginning of this year which went into a really nice seedbed (good frost tilth) but looks bad. No vigour, thin and spindly. Conclusion on that was just the cold with an added bonus of a bit slug hollowing.

quite late sown 15th April. Still cold for a while after that though.

I'd swap spindly barley for spindly wheat! 2 years ago I had some dreadful looking spring wheat but it you get the right weather it can still come up trumps. Can't sat the same for SB.

Agronomist and old man still reckon its something to do with roundup residue but I just can't see how - some of this was sprayed with roundup a month before drilling.

Depends if you believe any of what Don Huber says.

I think what he says may have an affect. But the only thing I don't quite understand is why sometimes it may happen and other times not. WW never shown any impact. It seems not have much of a pattern within the context of the amount of roundup sprayed pre drilling.

Where i DD spring wheat (where admittedly there was less residue but did roundup pre drilling to kill some meadowgrass etc.) I don't notice anything but then again maybe this field has not had a build up of roundup like the other one may have? - It was after failed rape. And to take this further Clive has sprayed roundup after DD wheat into rape? Hmm confusing..

Pure conjecture and only a wild guess but maybe if it's cold at drilling and the soil biology isn't active then it isn't working to release micronutrients that may have been locked up.

Possibly. Still something else is bugging me but can't figure out why.

I know Dockers of this parish like using plenty of Glyphosate a few times a year and has never noticed a thing.
Lots of the kiwi's double dosing stuff before seeding small seeds and not hearing much abuot glyph there at the moment but admittedly they would be the first doses for a number of years.

Did you test the seed for vigour etc?

No.

my spring barley has been awful, largely because I missed the moment to drill and ended up 'a day late and a dollar short' which meant not drilling into dry enough conditions. There is better establishment in some cultivated areas, but I think what I am seeing is the difference in soil moisture at drilling because it is just as good in some lighter undisturbed areas. I don't think there has been any effect from round up which was sprayed 3 weeks before drilling.

Did you get the spade out to dig up a few roots?

 

[Old Spot]

Pretty sure its not roundup, I have the same effect, I have sent some soils off from affected and unaffected patches in field for a soil microbe test. The samples have gone to Aus for analysis! New thing apparently will be interesting. We still have slugs working on the roots of the bad areas where there were volunteers or chaff.
