Table 15. — Data obtained in the varietal experiments with grain sorghums at the Wood- 
uard Field Station by sowing on two dates in 1914 and 1917. 
[Data in columns numbered 1 a:e for the first seeding, tho?e in columns numbered 2 for the second i fl- 
ing. The first seeding in 1914 was made on May 11 and the second seeding on June 2. In 1917 the hist

1 First seeding 50 per cent rice, second seeding 25 per cent ripe when the first hilling frost occurred en 
Oct. 12. 
- Flat 25 per cent ripe on Oct. 12, when the killing frost occurred. 
3 Flat 60 per cent rit e when the first frost occurred. 
* Plat 40 per cent i.e when the first frost occurred. 
White durra in the later-sown plat matured in 5 days less time and 
made a considerably higher yield than the earlier plat. Feterita 
matured in 11 days less time and although the grain yields were 
almost the same from the two seedings the total crop yield was more 
than twice as much from the later seeding. 
The kafirs in the later seeding failed to mature grain, hence results 
for them are not included in the table. The kaoliangs in general 
required less time in which to mature grain when seeded Late, though 
there were one or two exceptions. Four of the seven kaoliangs made 
higher grain yields when seeded on June 2 than when seeded on 
May 11. All of the kaoliangs made higher yields of total crop from 
the late seeding.
