Photograph of grasses. Weeping Love Grass (Eragrostis cruvula) in a cultivation study. Note the rows to the right of the white stick and the broadcast to the left of this. The area was seeded in April, 1939, on Chickasha fine sandy loam soil. # 340.

Photograph of little bluestem at the Red Plains Experiment Station. The bluestem was established in the spring of 1940 by 1500 pounds per acre seed-hay mulch. An effort has been made to thresh the seed from material by a small Allis-Chalmers combine. The hay contained considerable moisture, thus the threshed material contained considerable seed. Application was made broadcast on badly eroded sandy loam soil which had previously been cropped to cotton and grain sorghum. After spreading, the material was immediately rolled with a cultipacker. OK-8713.
