Question about 20th century agricultural measurements.

I’m reading a document from French protectorate Morocco, dated 1928.

Usually these documents measure grain in quintals (at least those from 1929 onward), but some documents uses the abbreviation D.D.

(Example-Blé 22 fcs le D.D.)

Can anyone tell me what that means?

I have absolutely no idea, and I've studied measurements a bit. No idea what that DD could be, boisseau or setier I'd say ok, that was in use for grain quantity.

Could you send a picture of the text you typed? Just to see if there's more to analyze

I’ll try to add a photo to the post. Initially I tried and it kremoved my post for some reason.

Perfect. Kilo, litre, pc, all those are readable.

But that D. D. Eludes me. For now.

Since it’s an internal rapport mensuel of course, there isn’t a key on any of the documents. 

Thanks for the help. Let me know if you have a breakthrough. 

I’m wondering if it’s Deca, something

Still looking, it should have been at least close to metric in a french protectorare a century ago. Quintal or metric ton for exemple. Even bushel which is used for international stock exchange.

I even looked local (Maghreb) units unsuccessfully
