New farmer oddly quiet (5)
I believe the answer is:
fresh
'new' is the definition.
('fresh' can be a synonym of 'new')
'farmer oddly quiet' is the wordplay.
'oddly' indicates alternate letters.
'quiet' becomes 'sh'.
The alternate letters of 'farmer' are 'fre'.
'fre'+'sh'='FRESH'
(Other definitions for fresh that I've seen before include "New; bracing" , "New; pert" , "Not canned or preserved" , "Saucy" , "New-fangled" .)
