Deliver new stock of local vegetables (5)
I believe the answer is:
calve
'deliver new stock' is the definition.
(give birth to calves - stock can mean cattle)
'of local vegetables' is the wordplay.
'of' says the answer is hidden in the clue.
'CALVE' is hidden in the letters of 'local vegetables'.
(Other definitions for calve that I've seen before include "Breed" , "left in grotto" , "Give birth to a young bovine" , "(Of ice) split from an iceberg" , "Split from the pack" .)
