Germination Pretreatment Requirement |
No treatment required 120, 183 3o C in moist sand, mid-Jan. 119 |
|
Seed Processing Needed e.g. awns |
Use hammermill to separate seed from forage, 3/16
screen. Scalped material in Model M2B
1/18 round with no air. Fine scalping
with office clipper 1/22 round, ½ air.
Larger quantities threshed much faster with Kurtz-Pelz thresher. Seed
must be very dry to thresh and screen properly. 138. |
|
Storage Requirements |
Cool, dry 138 |

|
Hand Collection Methods, Problems and Cost/Lb. |
Seed is very small and light. Flowering is indeterminate
and seed readily shatters. Recommend clipping heads and laying out on tarps
or in bags to dry. Must be
very dry to handle. Harvest when the center of the flower is dark
brown. 138 Contract 1993:
