Consternation caused by vegetables I'd raised (6)
I believe the answer is:
dismay
'consternation' is the definition.
(synonyms)
'vegetables i'd raised' is the wordplay.
'vegetables' becomes 'yams' (yam is a kind of vegetable).
'raised' says the letters should be written in reverse (going up in a down clue).
'yams'+'id'='yamsid'
'yamsid' backwards is 'DISMAY'.
'caused by' acts as a link.
(Other definitions for dismay that I've seen before include "Disappointment" , "Appal" , "Affright" , "Consternation, discouragement" , "Agitate" .)
