I'm the DM for a D&D campaign, set in a sort of "realistic-fantasy" setting. There's monsters and magic and stuff, but there's not enough of that for the average medieval community to see much more than the odd zombie attack or passing griffin.
Last session, one of the PCs came into possession of a large manor, which covers 2000 acres of good farmland, 500 acres of meadowland, and a nearby woodland that they have permission to harvest timber and the like from.
I was wondering if someone can help me figure out the yields of the following crops per acre; bear in mind, this would be medieval European technology, toward the later end of the High Middle Ages, specifically. Geographically, the region is similar to Maryland, Delaware or New Jersey.
- maize (see note)
- peanuts (see note)
- potatoes (see note)
- wild walnuts (kinda mixed in with the forest)
I've decided to include peanuts, maize, and a few other new-world nightshade crops (e.g. tomatoes and potatoes) in the world for flavor, and so that the peoples inhabiting more southerly climates could still rotate in a pulse crop of some kind (i.e. peanuts) during the growing season instead of wasting a third of their cropland letting it go fallow.
Also, for the grains that can do it, I'd also like to include an increased yield for the winter planting (e.g. planting in October vs. planting in March).
Problem is, Google has been supremely useless in finding a satisfying answer to this question, it's only interested in modern yields.
