What Yam sells for
Quality changes the price: silver is worth about a quarter more than regular, gold about a half more, and iridium double. Your farming level decides how often you get each.
| Regular | Silver | Gold | Iridium | Regular with Tiller |
|---|---|---|---|---|
| 160g | 200g | 240g | 320g | 176g |
| Farming level | Regular | Silver | Gold | Iridium |
|---|---|---|---|---|
| 0 | 97.02% | 1.98% | 1% | 0% |
| 5 | 69.42% | 19.58% | 11% | 0% |
| 10 | 45.82% | 33.18% | 21% | 0% |
Iridium quality only becomes possible with Deluxe Fertilizer, which is why the chance is 0% here.
Profit per tile
This is profit for one tile planted on day 1 of the season and replanted after each harvest, sold raw, after paying for seeds. It counts every harvest that fits before the season ends.
| Planted in | Harvests | Level 0 | Level 6 | Level 10 | Rank at level 6 |
|---|---|---|---|---|---|
| Fall | 2 | 203g | 239g | 260g | 12 of 17 |
Planted on day 1 of Fall, Yam is harvested on day 11, 21. Going from farming level 0 to 10 raises its profit by about 28%, mostly through better quality. It has to be replanted after every harvest, so the seed cost repeats: 120g over the season. For a different day, farming level, profession or fertilizer, use the Crop Profit Calculator.
Does fertilizer help?
| Nothing | Basic Fertilizer | Quality Fertilizer | Speed-Gro | Deluxe Speed-Gro |
|---|---|---|---|---|
| 239g | 173g | 150g | 258g | 278g |
For Yam, Deluxe Speed-Gro is the only one that pays: it lifts profit from 239g to 278g a tile. The others cost more than they bring in. Speed fertilizer works by fitting an extra harvest into the season; see Speed-Gro vs Deluxe Fertilizer for when that happens.
Sell it raw or process it?
| Machine | Makes | Price | Days in machine | Extra gold per machine per day |
|---|---|---|---|---|
| Keg | Juice | 504g | 3.75 | 92g |
| Preserves Jar | Pickles | 518g | 2.5 | 143g |
The last column is what one machine adds per day over selling the crop raw, if it is never idle. For Yam the better machine is the Preserves Jar (Pickles, 143g a machine-day). Preserves Jars earn more here, so keep your Kegs for crops with a higher gain. The Keg vs Preserves Jar tool splits a harvest across the machines you actually own.
In the greenhouse
Grown in the greenhouse all year (112 days), Yam makes about 1,314g a tile once established, from 11 harvests. Compare crops for a full greenhouse in Best Greenhouse Setup for Money.
How it compares
