MSc in Agronomy backs eating this type of veg! (7)

I believe the answer is:

organic

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

'type of veg' is the definition.
The answer and definition are not the same part of speech.

'msc in agronomy backs eating' is the wordplay.
'eating' indicates a hidden word.
'backs' is a reversal indicator.
'cinagro' is hidden within 'msc in agronomy'.
'cinagro' backwards is 'ORGANIC'.

'this' is the link.

Can you help me to learn more?

(Other definitions for organic that I've seen before include "Derived from animal or vegetable matter" , "(Compound) containing carbon" , "without fertiliser" , "In cargo (anag.)" , "Gin, Cora? (Anag)" .)

I've seen this clue in The Independent.
