Supporting being raised on farm (9)
I believe the answer is:
upholding
'supporting' is the definition.
(upholding is a kind of supporting)
'raised on farm' is the wordplay.
'raised' becomes 'up' ('up' can be similar in meaning to 'raised').
'on' is a charade indicator (letters next to each other).
'farm' becomes 'holding'.
'up'+'holding'='UPHOLDING'
'being' is the link.
(Other definitions for upholding that I've seen before include "Supporting" , "Maintaining" .)
