WHEAT PRODUCTION ON DRY LANDS. 55 
acre, one plat being sown with seed treated with formaldehyde and 
the other plat with untreated seed. The experiment was repeated on 
September 9. On both dates of sowing an irregular stand was 
obtained on the plats sown 4 inches deep. On November 5 counts 
were made of plants emerged on representative areas on each plat, 
and the results obtained are shown in Table 38.

The average yield obtained from the shallow seeding was 17.3 
bushels per acre and from the deep seeding 14.9 bushels per acre. 
The yields, however, were somewhat influenced by weeds, which 
Se numerous in the thin irregular stand obtained from deep 
seeding. 
Table 39 shows the yields obtained from sowing winter wheat 2 
inches deep, 34 inches deep, and 5 inches deep in the four years 1917, 
1918, 1919, and 1921. Sowings were made in duplicate twentieth- 
acre plats each year. On account of favorable moisture and tem- 
perature conditions at the time of sowing, practically no difference 
was obtained in the stands from the three depths of sowing during 
any of the years. It will be noted from Table 39 that the average 
yields obtained from the three depths of sowing were practically 
identical, indicating that the depth of sowing probably has no influ- 
ence on the yield if uniform stands are obtained.

RESULTS AT LIND. 
WINTER WHEAT. 
At Lind, depth-of-seeding experiments were carried parallel to 
the rate-and-date-of-seeding experiments with both fall and spring 
wheats. Data for the depth-of-seeding experiment with winter wheat 
are given in Table 40.
