Haygrass
A mixture of nutrient-rich grasses which yield large amounts of hay. Hay is edible for animals, but not humans.

Haygrass is a player-growable food crop with a high yield, and a slightly longer growing cycle. Haygrass can't be sown in hydroponics. Mature haygrass yields 18 hay.
Hay is inedible for humans; only rough grazers can eat hay.
Growing
Haygrass has a base growing time of 8 days, need a minimum soil fertility of 50%, and have a fertility sensitivity rating of 60%. The following table details how long it takes for haygrass to grow in each growable ground type, factoring in the plant resting time and being in ideal growing conditions:
| Ground Type | Gravel | Soil | Rich Soil | Hydroponics |
|---|---|---|---|---|
| Fertility (%) | 70 | 100 | 140 | 280 |
| Grow Time (days) | 14.75 | 12.09 | 9.75 | - |
| Base Yield/day[1] | 1.56 | 1.9 | 2.36 | - |
- ↑ Per plant
Haygrass has the highest yield per day, and therefore highest nutrition output out of any player-growable plant in the game in most cases - although rice in hydroponics, berry bushes, and agave all have better nutrition outputs compared to haygrass. However, none of the three aforementioned solutions would be feasible for sustaining livestock.
Food Production
The following table shows much haygrass it takes to sustain one baseline hunger rate animal, but only factors in the nutritional value of the yield, and the yield per day:
| Ground Type | Gravel | Soil | Rich Soil | Hydroponics |
|---|---|---|---|---|
| Raw | 20.52 | 16.83 | 13.57 | - |
| Kibble | 8.21 | 6.73 | 5.43 | - |
For the purpose of the variable nature of animal hunger rates; figures in this table have been rounded up to two decimal places, rather than to the next integer. If you're feeding animals that are being reared for meat, it's better to feed them raw hay than kibble; it's counter-productive to feed animals meat, to get less meat out of them.
The following is a list of hunger rates[1] (therefore multipliers) for some of the best animals for their purposes in the game:
- Cobra (economy/massed combat) - 0.07
- Cat (manhunter murdering/massed nuzzling) - 0.1
- Arctic/Timber wolf (hauling/rescue) - 0.18
- Snowhare (slaughtering) - 0.23
- Alpaca (cheap wool) - 0.45
- Husky (alcoholism) - 0.5
- Cow (milking) - 0.85
- Thrumbo (trophy) - 4.5
- ↑ At maturity
Economy
Haygrass' raw product is hay, which has a market value of 0.9 silver. The refined product with the largest profit margin is kibble, having a 12.07% profit margin.[1] The following table details silver per day, per plant. It only factors in the 50% selling markdown, the market value of the products, and the yield per day:
| Ground Type | Gravel | Soil | Rich Soil | Hydroponics |
|---|---|---|---|---|
| Raw | 0.7 | 0.86 | 1.06 | - |
| Refined[2] | 2.54 | 3.09 | 3.83 | - |
Haygrass is generally lackluster when it comes to economy, due to hay's remarkably low market value. Even kibble underperforms when compared to other food crops with fine meals.
