Cost, time and bonus at every level
Agriculture runs to level 20, adding +3% to production_rate and 60 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 3d 1h for the final level alone. Gems are only ever the optional instant finish; the study itself is bought with what your fields already make.
| Level | Total production rate | Power | Study time | Each resource | Gems to finish |
|---|---|---|---|---|---|
| 1 | +3% | 60 | 2m | 3,000 | 50 |
| 2 | +6% | 120 | 3m | 4,200 | 70 |
| 3 | +9% | 180 | 4m 30s | 5,880 | 98 |
| 4 | +12% | 240 | 6m 45s | 8,220 | 137 |
| 5 | +15% | 300 | 10m 8s | 11,520 | 192 |
| 10 | +30% | 600 | 1h 16m | 61,980 | 1,033 |
| 15 | +45% | 900 | 9h 43m | 333,360 | 5,556 |
| 20 | +60% | 1,200 | 3d 1h | 1,792,920 | 29,882 |
Taken from nothing to level 20 that is 9d 5h of raw study and 6,267,660 of each of food, wood, stone and iron — 25,070,640 resources in total. Levels above 10 additionally consume an advanced forging material, one more unit per level past the threshold, so the last 10 levels also need the forge working.
Where it sits in the tree
Agriculture belongs to the Economy branch — the production, construction and gathering line — everything that fills the stores. It has no prerequisites at all, so it is one of the first studies available to a new Academy. Studying it opens 5 further techs.
| Tech | Branch | Requires this tech at level |
|---|---|---|
| Logistics | Economy | 5 |
| Irrigation | Economy | 8 |
| Granaries | Economy | 10 |
| Quarrying | Economy | 5 |
| Woodcraft | Economy | 5 |
What it eventually opens: 31 studies sit downstream of Agriculture, counting every remove.
