rate of seeding tests indicate that a bushel of seed per acre is the most pro- 

 fitable rate of good seed to sow. 



The time of seeding tests at the College indicate that September 20th 

 to October 10th is the best time to plant. The results are as follows: a 

 plat that would yield at the estimated rate of 46 bushels per acre if planted 



Figure No. 5. A portion of a date of seeding test. The tall strips near the center and to the right 

 of the picture were planted October 10th. Between these two. are three strips, one planted November 

 21, 1918, and the other two in April, 1919. The spring plantings never headed out. 



September 25th, would yield 45 bushels if planted September 30th; 39 bushels 

 if planted October 15th; 20 bushels if planted October 25th; 10 bushels if 

 planted November 5th; 4 bushels if planted November 20th. Four spring 

 plantings were made from Rosen rj-e. None of them headed out. This 

 experiment shows that greatest success depends upon planting sufficiently 

 early in the fall. 



DISTRIBUTION OF CERTIFIED ROSEN RYE BY THE MICHI- 

 GAN CROP IMPROVEMENT ASSOCIATION.* 



The rapid increase in acreage of Rosen rye in Michigan has been due not 

 only to the superior yielding qualities of this rye but to the fact that ample 

 supplies of high grade seed, unmixed with common rye have been annually 

 available from the Michigan Crop Improvement Association growers. 



The Michigan Crop Improvement Association is an organization of Michi- 

 gan farmers particularly interested in increasing crop production through 

 the use of superior varieties, best methods of cultivation and fertilization. 

 This association may be joined by any farmer or seed grower of Michigan 

 interested in crop improvement. 



Through the association, large increases of desirable varieties kept pure 

 by careful inspection, are obtained in a relatively short time. Improved
