LUIS – (Trifolium alexandrinum L.)
This variety has been obtained by a decennial selection work with material grown in the province of Pisa. It adapts itself very well to the hilly and level surroundings of central Italy. It resists well to alkaline and saline soil. It can be used in a double way: fodder/seed. Cold proof, it's good for autumnal sowing. It has been registered with the "Registro Nazionale delle Sementi Elette di specie agrarie" since 2002.

Use and productivity:
Trifolium alexandrinum provides a fodder, that is appetizing to livestock, valuable quality and high digestibility. It has a nutritious value such as medicago sativa, but the latter usually shows a lower content of fibers. It can be inserted into the cropping system as main growing (field alternated of short duration) or intercalated (spring/summer herbarium ).
It has to be considered an improving plant for its taproot and rich in tubercles apparatus. Adversities that can cause serious concern are limited; among these, we remember: Erysiphe polygoni, it appears on the leaves, and it slowly thickens until covering and appearing as a yellow/white efflorescence. Among other possible cryptogams we remember Phytium effusarium that can cause damage to the plants.
