Paddy crop (4)
I believe the answer is:
rice
'paddy crop' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rice that I've seen before include "... his librettist - cereal" , "Paddy field crop" , "Seeds from the paddy field" , "Grain for food" , "Cereal grass" .)
