Of course. Although I'd say it differently: pre-state people probably practiced some amount of farming, and niche-creation. But what we call a primitive state is precisely the superstructure needed to gather lots of them and make them farm for your benefit.

And to make sure it worked to your benefit (as the king) it was important that they farmed a limited number of things which were easy to keep track of, and easy to transport, and hence easy to tax. Like wheat or barley or rice, which you can inspect any time, and which ripens on a predictable date, on which your soldiers can show up to collect the rent. (And unlike potatoes.)
