Estimating the annual yield of a plot of land

tombe said:

Hi everyone, apologies for another novice question:

Let's say the average wheat yield is 8 tonnes per hectare and I have a hectare that I want to use for wheat production one year. Given that some types of wheat can be planted in the spring and harvested in the autumn, and others can be planted in the autumn and harvested in the spring, should I expect 8 tonnes a year from that hectare or around twice that if I plant twice a year? Is it right to use a plot of land twice a year for the same crop? I expect it would cause soil depletion, but perhaps planting something else in that hectare the next year will help with that?

I think you would be lucky to harvest 8 tonnes from a single hectare. The 8 tonnes per hectare is an average for big and small fields. Smaller fields contain a greater proportion of headland (outer border) which will much yield less than the middle of the field. In a single hectare field that could be 50% of the area or more, compared to 25-30% or less in a field size of 10 or 40 hectares.
