What practical measures did the people of mesopotamia take to grow crops on a regular basis

The people of Mesopotamia had two rivers namely the Tigris and Euphrates. They made canals and other man made waterways to use for irrigation and to supply their plants with water. Using these irrigation tools they channeled water from rivers to their crops. Irrigation helped keep the soil moist, and the river water delivered nutrients to the soil. In this way they grew crops on a regular basis.

Few crops that they grew were- barley , wheat, vegetables, lentils, fruits etc.

that’s true, tatiana prouskouriakoff established that the inscriptions were primarily historical.   they recorded events in the lives of mayan rulers and their families.
