If you're looking for Europe such data does not exist. The closest you can come is Walter of Henley from the 13th century. https://archive.org/details/walterhenleyshu01cunngoog
He wrote the standard book on stewardship that was used from the 13th century to the 16th century, so likely very accurate.
Wheat took 2 bushels of seed per acre (each bushel weighed 60 lbs) and yielded 10 bushels or 8 bushels net (which was called a quarter). 2.5 acres with traditional agriculture is the total farmland needed to support a person with two field agriculture. Three field supports in theory 20% more. One field supported about 20 people per square mile. One field is where a field is kept in constant cultivation, but is surrounded by a lot of land supporting livestock which supply dung for fertilizer. Slash and Burn agriculture can support 10 persons square mile - this was the standard agriculture in Germany during the Migration Period, so the Romans greatly exaggerated the number of Barbarians they faced.
The quality of land is very important to yields. Good bottom lands (these are the lands on the flood planes of rivers) can yield 10 times the normal yields and one can expect at least double yields. Rice supports more than wheat, but is more labor intensive per acre. In South China the rice paddies are surrounded by banks which allow them both to be flooded and drained. Rice eels are also raised in the flooded paddies, when not using this system and dry farming rice the yields are very low by contrast.
Corn (AKA maize) also has much higher yields per acre than wheat and takes little effort to grow - the reason Central and South America supported such large cities.
Crop yields and how much they can support is a very complicated subject, as is how much land was under cultivation and the methods used. What you're trying to find out would likely take a decade of field research even for a country and just for a century.
In Europe it's also complicated by the fact that animal breeds are not the same and have greatly improved. An adult Medieval sheep weighed only about 60 bls compared to 120+ for a modern one and an adult Medieval cow only about 400 lbs (I'm not sure of the modern weight but at a guess I would say 3 to 4 times larger). Keep in mind that one had to support livestock through the winter on grain (mainly oats) and hay which was not a field crop and there was a very limited amount of meadow producing hay (worth 3 times what farmland producing wheat was in the Middle Ages).
