I'm worldbuilding an earth-like planet with no axial tilt, in order to maximize extreme climates (like deserts). However, there will still be pockets of fertile land, which will be populated by humans, with a technological level similar to that of the ancient civilizations of the fertile crescent, like the babylonians.
One of the side effects of not having an axial tilt is the minimization of seasons. So it got me thinking, on how this would interphere with an agricultural society, namely with seeding and harvest seasons...
Would it be feasible to cultivate seasonal plants in such an environment, like wheat or grapewhine? Or would it be better to use plants that are not seasonal, like barley or rice (if my research doesn't fail me they have seasons, but may be perennial)?
I would like my civilization to have wheat and wine, would it be possible?
