Let's be very charitable and figure out a scenario where this could be true.
Suppose, a farmer has a farm which produces 1 unit of crop. Farmer uses 0.8 of the crop for subsistence and sells 0.2 of the crop. They get $600/acre.
Now, crop yields go up 5x, so now the farm produces 5 units of crop. Subsistence needs are the same, so the farmer is now able to sell 4.2 units of crop. This is 4.2/0.2 = 21 times more revenue or $12,600/acre.
