Alfalfa Protein Content

Medicago sativa L.

Crude protein content in alfalfa is a key indicator of forage quality, depending on the growth stage, and ranges from 18–25% on a dry matter basis at optimal harvesting time.

In the reference 66 varieties crop Alfalfa, where this is mentioned in the description.

The crude protein content in alfalfa is highest during the branching stage, reaching 25% or more. During the optimal harvesting period, which occurs from the bud stage to the beginning of flowering, the values vary within the range of 17–22%. As the plant enters the flowering stage, protein concentration decreases to 15–16% due to the accumulation of structural carbohydrates and the process of stem lignification.

A decrease in protein levels below 14–15% indicates that the plants have been left in the field too long or that there has been a failure in agronomic practices, specifically high soil acidity, which limits nitrogen fixation. To maintain high protein quality, phosphorus-potassium nutrition and strict adherence to harvest timing are critical, as overly early harvesting can negatively affect the longevity of the stand.
