How do they differ capitalist and non capitalist in agriculture?

Capitalists get paid the market price for what they produce. Capitalist farmers wanting more money grow more stuff, or grow stuff that makes more profit. Non capitalists grow stuff and get paid or don't get paid wether they grow stuff or not. There is no monetary incentive to grow more than you can eat. However you can get beaten or punished for not growing enough stuff by the people that pay or don't pay you to grow it.
