analyses. The seed production of Dakota Kursk is also better, 

 especially in dry seasons, than that of the Siberian strain. Under 

 more humid conditions this millet may be the more profitable variety, 

 but in the Great Plains it is probable that Dakota Kursk will give 

 better average results. 



COMPARATIVE YIELDS OF SELECTED STRAINS OF MILLET. 



In testing the comparative value of the progeny strains of millet, 

 two methods of planting have been used. These were (1) ordinary 

 plats of one-tenth or one-twentieth acre in size, with the seed drilled 

 at the rate of 20 pounds per acre, and (2) cultivated rows 8 rods long, 

 seeded at the rate of 2 pounds per acre. In most cases the plats have 

 been planted in duplicate or triplicate, and the rows in all tests have 

 been planted in duplicate. 



At the Akron Field Station the two varieties of millet which have 

 given the largest yields are Siberian and Kursk. These varieties 

 have been represented in the comparative tests by uniform strains 

 selected for drought adaptation. The two strains of Siberian millet 

 have given slightly higher yields than the six strains of Kursk millet, 

 both in drilled plats (Table II) and in cultivated rows. Of the strains 

 of Siberian millet, A. D. I. No. 4-3 is a better hay type than No. 4-5, 

 being finer and more leafy.

Among the strains of Kursk millet, A. D. I. No. 3 and a selection 

 from this strain, A. D. I. No. 3-2, have given the highest yields at 

 Akron. (See Table II.) Those two strains are practically identical 

 in type of plant and have been given a common name, Dakota Kursk. 

 No. 3-2 has given somewhat the greater yield, both at Akron and at 

 Newell, and hereafter the strain bearing this number will be used as 

 far as possible for distribution to farmers.
