10 years. During this period the four most produce 

 tive varieties of each year for seed included Mammoth 

 Yellow six times; Blackbeauty five times; Hollybrook 

 four times; and Edward, Haberlandt, Ebony and Wil- 

 son each three times. 



In the last five-year period, Hollybrook averaged 15.1 

 bushels of seed per acre; Blackbeauty 13.9 bushels; 

 Mammoth Yellow 13.3 bushels; and Ebony 12.4 bushels. 

 The varieties which lead in seed production have rath- 

 er coarse, erect stems, and are medium late. The early 

 varieties never rank high in yield of either seed or for- 

 age. 



The farmer will make no mistake in choosing the 

 Mammoth Yellow for this latitude. It is a rank grow- 

 ing variety, has medium large yellow seed, and requires 

 about 135 days to mature a crop of seed. It produces 

 good hay. Hollybrook produces a smaller plant and 

 has yellow seed. It requires about 125 days to make a 

 crop of seed. Blackbeauty and Ebony are black seed- 

 ed varieties. 



For the production of hay. Mammoth Yellow, Holly- 

 brook, Ebony and Biloxi are recommended. On good 

 land they produce from one to two tons of hay that is 

 of high feeding value, being similar in composition to 

 ha}" from cowpeas, clover and alfalfa.
