Food cultivation (7)
I believe the answer is:
nurture
This clue is a double definition.
'food' is the first definition.
(thesaurus)
'cultivation' is the second definition.
(thesaurus)
(Other definitions for nurture that I've seen before include "Cherish (an ambition)" , "Cherish (a hope)" , "Encourage development of (a child)" , "Feed (but not nature?)" , "Cultivate" .)
