Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
Lolium multiflorum (Italian rye-grass, [2] annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. [3] It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. [4] [5] It is also grown as an ornamental grass.
[2] [3] It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera. They are characterized by bunch-like growth habits. Lolium is native to Europe , Asia and northern Africa , as well as being cultivated and naturalized in Australia , the Americas , and various oceanic islands.
Common names by which it is known include annual ryegrass, a name also given to Italian ryegrass (Lolium multiflorum), rigid ryegrass, stiff darnel, Swiss ryegrass and Wimmera ryegrass. [1] It is a native of southern Europe, northern Africa, the Middle East and the Indian subcontinent and is grown as a forage crop, particularly in Australia ...
The transpiration ratio is the ratio of the mass of water transpired to the mass of dry matter produced; the transpiration ratio of crops tends to fall between 200 and 1000 (i.e., crop plants transpire 200 to 1000 kg of water for every kg of dry matter produced). [10]
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

Leymus arenarius can grow exponentially in terms of height and root development in the presence of nitrogen.L. arenarius is known to take up nitrogen into its root system. . Increasing nitrogen concentrations can promote growth, as over time, the plant mass above the surface may not change, but nitrogen will accumulate in the root syst
One of the most significant differences in hay digestion is between ruminant animals, such as cattle and sheep, and nonruminant, hindgut fermentors, such as horses. Both types of animals can digest cellulose in grass and hay, but do so by different mechanisms. Because of the four-chambered stomach of cattle, they are often able to break down ...
