Urge factory to produce fruit (8)
I believe the answer is:
eggplant
'fruit' is the definition.
(I know that eggplant is a fruit)
'urge factory' is the wordplay.
'urge' becomes 'egg' (as in egging someone on).
'factory' becomes 'plant' (a manufacturing plant).
'egg'+'plant'='EGGPLANT'
'to produce' acts as a link.
(Other definitions for eggplant that I've seen before include "US name for aubergine" , "What goes into moussaka" , "It's also called aubergine" , "Its fruit is aubergine" , "Vegetable" .)
