Value puts pressure on crop (5)

I believe the answer is:

price

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

'value' is the definition.
(I know that price is a type of value)

'pressure on crop' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'on crop' becomes 'rice' (I can't explain this - if you can you should give a lot more credence to this answer).
'p'+'rice'='PRICE'

'puts' is the link.

Can you help me to learn more?

(Other definitions for price that I've seen before include "Betting odds" , "Jordan?" , "Fanny?" , "Listed cost" , "Cost of an item" .)

I've seen this clue in The Mirror.
