Yam requires new seeds after each harvest when you replant.

In a 27-day growing window, one tile gives 2 harvests and 320g revenue. Deducting 120g in seeds leaves 200g net profit, or 7.41g per growth day. This example uses normal quality, no profession, no fertilizer cost and immediate replanting.

Growth acceleration & last planting day

Outdoors, planting by the last viable day allows a harvest on day 28. A crop taking a full season needs a longer window. Season-free areas do not have a seasonal planting deadline. Repeat-harvest intervals stay unchanged.
