Adding quotes around the dimension values will most likely break the wms
standard, and standard clients
will simply ignore them.
In other words, to a compliant standard, the above list defines the
following possible values:
"Cereals"
"Cereals"
"Oil
crops"
"Root"
ant then they will add to the GetMap request ...&DIM_CROP="Oil&...
Long story short, your use case places you out of the WMS standard reach,
and the solution will break
any standard client.
My suggestion: don't try to use human readable values for your dimensions,
use codes and have a lookup
table to turn them into human readable ones for your clients
