In Senegal it chiefly produces fruit (6)
I believe the answer is:
litchi
'fruit' is the definition.
(litchi is a kind of fruit)
'in senegal it chiefly' is the wordplay.
'in' says the answer is hidden in the clue.
'LITCHI' can be found hidden inside 'senegal it chiefly'.
'produces' is the link.
(Other definitions for litchi that I've seen before include "Asian tree" , "Chinese tree; its fruit" , "piece of fruit" , "Edible Chinese fruit" .)
