Well, according to Dondlinger 1908, in The Book of Wheat, p. 77, the modern harvest time is in June. He lists that for several countries, all as of 1908. I think Pliny or Columela mentions that different varieties of wheat take longer growing seasons before harvest, and that the higher-yield varieties, by ancient standards, take longer than lower-yield ones.
