Produce much, and many more (4)

I believe the answer is:

farm

I'm a little stuck... Click here to teach me more about this clue!

'produce' is the definition.
('farm' can be a synonym of 'produce')

'much and many more' is the wordplay.
'much' becomes 'far' (I've seen this in other clues).
'and' says to put letters next to each other.
'many more' becomes 'm' (I am not sure about the 'many' bit.**).
'far'+'m'='FARM'

Can you help me to learn more?

(Other definitions for farm that I've seen before include "See 5" , "Manage land for crops or livestock" , "Cold Comfort --" , "Rural establishment" , "Use the land" .)

I've seen this clue in the Evening Standard.
