Rye is an annual temperate grass or cereal crop, grown as either a forage- or grain crop. It is categorised as a forage cereal together with Oats and Triticale. Forage cereals produce forage for autumn, winter and spring. As a forage crop it can be utilised as grazing, silage or hay (if cut at a vegetative stage).
Often produced under irrigation, but requires at least 400 mm rainfall per annum for Winter rainfall areas or 500 mm rainfall per annum for Summer rainfall areas.
