DATE-OF-SEED1NG EXPERIMENTS. 
In 1914 and 1917 the grain sorghums in the varietal experiments 
were duplicated on different dates. The first seeding in 1914 was 
made on May 11, while the second seeding was made on June 2, or 
22 days later. In 1917 the main varietal plats were seeded May 15 
and the duplicate plats on May 23, or 8 days later. The data previ- 
ously presented are for the earlier seedings. The behavior of the 
varieties when seeded at different times differs greatly, and certain 
adaptations and limitations of varieties to climatic conditions are 
emphasized. Data for both seedings in the varietal experiments in 
1914 and 1917 are shown in Table 15 for direct comparison. 
In 1914 the growing periods of the milos did not vary greatly with 
the date of seeding. The standard milos were very little taller from the 
first seeding than from the second, but the earlier seeding of dwarf milo 
grew approximately 1.5 feet taller than the later plats. In yields of 
grain the earlier plats were much above the later seeded duplicate 
plats with one exception. Standard White milo (C. I. No. 352) made 
a higher yield of grain from the later seeding than on the earlier plat, 
due to the fact that the earlier plat was damaged by birds to a con- 
siderable degree.
