Barley is a widely adaptable crop.
It is currently popular in temperate areas where it is grown as a summer crop and tropical areas where it is sown as a winter crop.
Its germination time is one to three days.
Barley grows under cool conditions, but is not particularly winter hardy.

Barley is more tolerant of soil salinity than wheat, which might explain the increase of barley cultivation in Mesopotamia from the second millennium BCE onwards.
Barley is not as cold tolerant as the winter wheats (Triticum aestivum), fall rye (Secale cereale) or winter triticale (× Triticosecale Wittm.
ex A. Camus.),
but may be sown as a winter crop in warmer areas of  Australia and Great Britain.

Barley has a short growing season and is also relatively drought tolerant.
