Rice plant

Rice plant

A short, fast-growing crop that yields small edible grains. Its great nutritional output and ease of cultivation has made it the economic core of many great civilizations. While rice grows quickly, it is sensitive to soil fertility and will not fare well in poor soil.

Rice plants yield rice, a fast growing crop. While its speed nets a high overall yield per tile per day, each plant gives the least food per harvest, so rice takes a high amount of labor for a given amount of food. Therefore, it is a good option for newer colonies, but may be gradually phased out as a food reserve is established.

  • Analysis[edit]

    Rice plants' daily nutrition (per tile) is fractionally higher than corn and potatoes (102.7% and 105.4% in regular soil, respectively), though rice's greatest strength is its quick and stable growth.

    The short maturation time makes it ideal for establishing a colony, as an 'emergency' food crop when food runs low, for biomes with short growing seasons, and as a 'last planting' crop when winter is fast approaching. As rice is harvested so frequently, damage from destructive events like blight and cold snaps has a much smaller impact than with other crops. Each individual rice harvest is both faster and smaller than other crops, so less is lost in a single event. The fast growing speed also has a use in leveling up the Plants skill.

    However, this also means rice requires far more labor to reap and sow for the same nutrition compared to potatoes and especially corn. Rice takes 183% the work than potatoes, and 366% the work of corn. While corn gives slightly less nutrition per tile, you could plant in more tiles for the same yield (assuming space isn't limited). Therefore, rice becomes less viable past the midgame, unless the colony is in an emergency.

    While rice is no more affected by soil fertility than corn, rice will grow even faster with high fertility, magnifying the innate strengths (quick, stable food) and weaknesses (work) of that fact. And unlike corn, rice can grow in hydroponics. While rice provides significantly more nutrition over time than any other hydroponics crop, it requires a harvest and replanting every other day to do so.
