Italian Ryegrass

Lolium multiflorum L.(common names: Italian Ryegrass, Loiessa) is a grass of Mediterranean origin; it was introduced to Italy, in the Po Valley, from where it spread to Europe and other continents, becoming one of the most important grasses for livestock feed. An annual or biennial plant with a high degree of establishment and aggressiveness, high weed control capacity, it lends itself to excellent dry matter production and high nutritional values. It is usually used in monoculture or in the formation of mixed grasslands. The forage production achievable with the first cut averages 35-40 t/Ha. The green matter is equivalent to 9-11 t/Ha of dry matter with 5500-6500 Forage Units.

There are two subspecies of Italian Ryegrass:

Lolium multiflorum ssp. Italicum: excellent cold resistance, low alternativity, can form biennial grasslands. Generally, it can be sown in autumn to be mowed in May and, under favorable conditions, with cool environments and mild temperatures, extend its vegetative cycle to be then grazed or used for hay production.

Lolium multiflorum ssp. Westerwoldicum: an alternative annual plant, aggressive, with a high establishment rate in areas with a temperate climate. Sown in August, it can be grazed until February with excellent results, and then produce excellent hay, baled, or ensiled in May.

There are two varieties with different numbers of chromosomes:


Diploid Varieties (2N)
They are characterized by smaller seeds, thinner vegetative mass, lower water content in the forage, and are particularly used for hay production.

Tetraploid Varieties (4N)

Double the number of chromosomes compared to diploid varieties, very high production potential, larger seeds, taller stature, wider leaves with higher water content in the forage. They lend themselves very well to be baled or ensiled.
