Every crop ranked by what one tile earns per day, with the numbers shown.

Crops are the one thing on this site that can be ranked with arithmetic instead of an argument, so that is what this does. Every placement below comes from one number: gold per tile per day, over a full 28-day season, at base quality. The tier boundaries and the notes are editorial, and a few crops are worth more than their number says. Corn and Ancient Fruit are the obvious two, and both say so.
For each crop: harvests in a 28-day season, times yield per harvest, times sell price, minus seeds (one for a crop that regrows, one per harvest for one you replant), divided by 28. Seed cost is the General Store price, which is twice the seed's value in the game files, with a listed exception for anything bought somewhere else or not bought at all. No fertiliser, no Tiller, no quality stars and no extra-harvest luck, because those scale nearly the whole table at once and change the gold without changing the order.
gross = harvests x yield per harvest x sell price seeds = 1 if the crop regrows, otherwise one per harvest profit = gross - seeds x seed cost gold/day = profit / 28
Blueberry, worked through: four harvests, three berries each, 50g a berry is 600g off one tile. Take off the 80g seed and spread the 520g across the season and it comes to 18.6g a day, which clears the 18g S-tier line by half a gold. Tap any crop to see its seed cost, sell price, harvests and gold per day, and check its placement yourself.
Crops die when the season turns, so each season is ranked on its own. The Greenhouse tab drops that limit and pits everything against everything.
Indoors nothing dies at season's end, which makes this the only board where Summer and Fall crops can be compared head to head.
