Golden vegetable in cultivated land (7)
I believe the answer is:
orchard
'cultivated land' is the definition.
(I've seen this before)
'golden vegetable' is the wordplay.
'golden' becomes 'or'.
'vegetable' becomes 'chard' (chard is a kind of vegetable).
'or'+'chard'='ORCHARD'
'in' acts as a link.
(Other definitions for orchard that I've seen before include "Plantation of fruit trees" , "Field of fruit trees" , "Fruit-tree plot" , "Place of fruit trees" , "Plot for fruit trees" .)
