Days barley to harvest after planting?

Barley can be harvested 75 to 120 days after planting, depending on the variety and the growing conditions. Early maturing varieties can be harvested in as little as 75 days, while later maturing varieties may require up to 120 days. The most common way to determine if barley is ready to harvest is to look at the color of the kernels. When they turn from green to yellow or brown, they are ready to be harvested.
