Peasants made a customary payment to the Church out of what they grew. What was it, and how much did it come to?

توضیح

The payment was a share of the harvest handed over to support the parish and its clergy, and custom fixed it at one part in ten rather than leaving it to whatever the priest asked for. The labour answer is the closest trap, because peasants certainly did owe days of work in the fields, but that duty was owed to the lord of the estate and was quite separate from what the parish received.
