So, I'm no historian, but I can google.
So I googled the first 2, largely manual, farming styles that came to mind - paddy fields, and tea - and those were pretty much all women doing the work.
So then I thought, but that's biased, lets look at some others
Wheat farming - once I got out of the mechanised stuff, I found 'Wheat Farming in the Punjab' and there were both women and men hand harvesting.
So I thought some more. Grapes, Oranges - fruit harvesting - women and men again
Ploughing - the one that requires strength apparently (I know almost nothing about this) - finally mainly men... no.. hangon, plenty of men, but also a fair few boys and old men (so strength can't be all-important then), and when no animals or tractors where involved, there it was, women with the picks and hoes.
So, my googling leads me to disbelieve you karbon.
