My Autumn Bliss raspberrry bushes, about thirty, have produced excellent
crops for the last 6/7 years. This year about half of the bushes are short
in growth and have light green leaves. They are not producing, although
the
remainder are producing an excellent crop. The bushes are pruned back to
ground level every February.
Are they lacking the proper fertiliser, or just getting beyond it? Any
advice would be welcome.

As my oldest raspberry planting is over 15 years old and still producing,
I doubt that yours is "just getting beyond it." It's some problem with
disease or fertility or (not knowing your layout at all) possibly a growing
competition with trees for resources after seven years. (And I can tell you
from experience that trees can send out roots a surprisingly long way to tap
into richer, better watered territory.)
