'farm' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'can cut credit in outlets' is the wordplay.
'cut' means to remove the last letter.
'credit' becomes 'cr' (abbreviation).
'in' is an insertion indicator.
'outlets' becomes 'shops' (shop is a kind of outlet).
'can' with its last letter taken off is 'ca'.
'cr' placed into 'shops' is 'shcrops'.
'ca'+'shcrops'='CASH CROPS'

'produce' acts as a link.
