Refute it? Maybe about right. It could provide apples (5,4)
'it could provide apples' is the definition.
The definition suggests a singular noun which matches the answer.
'refute it? maybe about right' is the wordplay.
'maybe' is an anagram indicator.
'about' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'refuteit' with letters rearranged gives 'fuittree'.
'fuittree' placed around 'r' is 'FRUIT TREE'.

(Another definition for fruit tree that I've seen is "Perhaps apple".)
