From research on the relationships of measurable plant characteristics to forage quality has come a quite simple and relatively accurate estimate of the feeding quality of the standing alfalfa crop.
The method requires:
- The target average forage quality to be stored. (Example 150 RFV [relative feed value])
- A 2-square-foot frame
- A simple definition for alfalfa maturity based on easily identifiable traits.
- An estimate of the approximate percent harvest loss expected (10 percent loss under the best conditions; 15 percent may be average. (Expect higher losses under less than optimal harvest conditions.)
