Last or First?

A few days ago I harvested my yacon (Polymnia edulis). My season outside is a bit too short to get good yields outside, so I grow in large pots which I move in to the living room in autumn and grow on for 2-3 months. This year I was a bit late and one of the plants had been cut right down by an early frost and the other was badly damaged. Both sent up new shoots when they came into the house. 
The first harvest of 2021 or the last of 2020?
