Useful Swathing Info

Here are some useful links regarding swathing timing of various crops.  At the bottom of this post is a chart for seed moisture and swathing timing.  These moisture levels were developed through years of research by OSU.

Response of Seed Yield to Swathing Timing in Tall Fescue and Creeping Red Fescue

Using Seed Moisture as a Harvest Management Tool to Determine Swathing Time in Grass Seed Crops

Response of Seed Yield to Swathing Time in Annual and Perennial Ryegrass

Growing Meadowfoam


Crop                                      Optimum Moisture 
                                                        for Swathing           
Meadowfoam                                  42%
Crimson Clover                               35%
Annual Ryegrass                         43-46%
Tall Fescue (forage)                    40-43%
Tall Fescue (turf)                        35-41%
Perennial Ryegrass                     35-43%
Orchardgrass                             42-46%
Fine Fescue                               20-35%

Fescues, perennial ryegrass, and annual ryegrass will lose about 2-3% moisture per day while orchardgrass loses about 1% per day.  Meadowfoam loses 2% moisture per day.
