Produce work on short credit (4)
I believe the answer is:
crop
'produce' is the definition.
(I've seen this before)
'work on short credit' is the wordplay.
I cannot quite understand how this works, but
'work' could be 'op' (short for opus) and 'op' is present in the answer.
'credit' could be 'cr' (abbreviation) and 'cr' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for crop that I've seen before include "Dock" , "Harvest yield" , "It's produced at harvest time" , "Yield from cultivation" , "hair style" .)
