June 3 in 1918. The late seeding was made on June 7 in 1917, on 

 June 9 in 1916, on June 10 in 1914 and 1915, on June 12 in 1918, and 

 on June 20 in 1919. 



Four varieties, Dwarf milo (C. I. No. 332), Feterita (C. I. No. 182), 

 Dawn kafir (C. I. No. 340), and Manchu kaoliang (C. I. No. 171), 

 were included in these experiments. One plat of each variety was 

 seeded at an early date, one at a normal date, and one at a late date 

 each year. In the early and late dates the varieties each occupied 

 tenth-acre plats, and in the normal date they occupied twentieth-acre 

 plats for each year during this 6-year period. 



The results obtained from the date-of-seeding experiments are 

 shown in Tables V to IX, inclusive. The results for each variety are 

 shown separately first, and the averages of the four varieties are then 

 included in one table to facilitate comparison.

DWARF MILO. 



Table V shows the agronomic data for Dwarf milo in the date-of- 

 seeding experiments. (Fig. 5.) This table shows that the stands 

 obtained from the different dates of seeding are not comparable in all 

 cases in the same year or in the different years. The row space to the 

 plant ranged from about 5 to 8 inches in 11 of the 18 plats used in the 

 experiment. In 6 of the 7 plats remaining, the row space ranged 

 from 10 to 17 inches, and in the other plat it was 27 inches. The thin
