There are milling wheat growers and feed wheat growers hoping for a premium. Heavy land in the East and Midlands can grow consistently high protein milling grades with a good yield and little penalty over a feed type.
IMO it's better to think of margin rather than just yield. You'd want to regularly be achieving a £15/t premium for milling to justify the extra inputs required and accept that some years the weather prevents you meeting the spec so you want a higher premium to see you through the bad years when you have an expensive heap of feed. Varieties like Skyfall changed the game somewhat - feed wheat costs, a reasonable septoria score, good quality and an early maturity date though it has fallen over to yellow rust now. Lots of feed growers were getting useful premiums from this when demand was good and a decent yield when the premium wasn't there.
Group 3 soft milling wheats fell out of favour when no new good varieties came through the Recommended List system & premiums fell. We used to have a great export market when the likes of Consort, Claire, Robigus etc were at the top of the RL yields table. These growers jumped into Group 1 & 2 varieties when they superseded the Gp 3s and many have gone back to Gp 4s when these had the highest yields in the List and the milling market was oversupplied.
Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.
If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.
Common options for rejuvenating swards include:
Take a silage cut, probably into bales, remove the material and start again with the aftermath...
