at least some of the info above is likely to change with the hearth & home update. devs have shown new foods/recipes and plant-able crops in some of their teasers. (no idea yet where any of those new foods will be found) also there are 4 more biomes to be added, which will likely add even more to the farming aspects. i'd add to what others have already said in that the farther you progress in game, the less valuable early crops become, to the point they become practically useless. hopefully this can be addressed with new updated recipes!
