Yield from what's sown in garden, reportedly (4)
I believe the answer is:
cede
'yield' is the definition.
(I know that yield can be written as cede)
'what's sown in garden reportedly' is the wordplay.
'what's sown in garden' becomes 'ced' (I am not sure about this - if you are sure you should believe this answer much more).
'reportedly' becomes 'e' (I've seen this in other clues).
'ced'+'e'='CEDE'
'from' is the link.
Can you help me to learn more?
(Other definitions for cede that I've seen before include "Transfer" , "21 across" , "Surrender or yield" , "Allow" , "Yield formally" .)
