I want to know the answer to the following question:
The the Ur III period, what crop had Sumerians switched to from wheat for their primary crop?
All the background I'm provided with is that "As is known from the "Sumerian Farmer's Almanac", after the flood season and after the Spring Equinox and the Akitu or New Year Festival, using the canals, farmers would flood their fields and then drain the water.". Is that enough to answer the question?
Answer: no
