Harvest of more appropriate crops (4)
I believe the answer is:
reap
'harvest' is the definition.
(I know that harvest can be written as reap)
'of more appropriate crops' is the wordplay.
'of' says the answer is hidden in the clue.
'REAP' is hidden in the letters of 'more appropriate crops'.
(Other definitions for reap that I've seen before include "Save harvest, glean" , "Derive as advantage" , "Cut the corn" , "Harvest (a crop)" , "Gather 23dn" .)
