Barley Progress,Just coming into head

This is Grace, John, Izzy and Wiz standing in our latest barley crop, we have some planted at 30kg ha of seed, some at 60kg of seed and some at 90kg ha of seed. There is a marked difference between the 30,60 and 90kg rates in terms of crop height, the photo is of some of the 90kg ha.
This crop is close to 60 days since germination.
The crop will have to finish on subsoil moisture most likely, there is a chance of some more rain although it is only a chance.
