Barnyard grass. The cultivation of Panicum crus-galli, L. , has 

 not bee a carried on extensively in this state. This grass, 

 although usually regarded as a weed, is frequently used as a f . r- 

 age plant in western Iowa and along the Mississippi in eastern 

 Iowa. It occurs abundantly as a roadside and garden weed 

 throughout Iowa, and is a conspicuous grass in sloughs and in 

 cornfields in the Missouri and Mississippi bottoms. Consider- 

 able success has beea obtained with this grass in Massachu- 

 setts.* 



F. Lamson-Scribner says-.f 



"At the Hatch experiment station, in Massachusetts, the 

 crop produced was very uoiform, averaging seven feet in height. 

 The yield was at the rate of 11,207 pounds of straw per acre 

 and 66.7 bushels of seed. When sown for silage or for soiling 

 at the rate of one peck of seed to the acre, the yield was at the 

 rate of from fifteea to eighteen tons per acre. A field sown 

 July 26, after a crop of hay was removed, yielded twelve tons 

 per acre. It is very much liked by stock, and is a valuable 

 forage plant for feeding green or for the silo. It is not so well 

 adapted for hay, as it is a course, succulent grass, and rather 

 difficult to dry. " 



Dr. Kennedy states that from the results from seeds sent 

 out by the division of agrostology, United States department 

 of agriculture, I of the seventy-eight packages sent out for trial, 

 most of the trials proved to be failures, owing to the lateness 

 of planting and the severe drouth.
