WHEAT PRODUCTION ON DRY LANDS.. We 
Yields are not uniform in their relation to rate of seeding in these 
_ experiments, other factors apparently having more bearing on results 
than the rate of seeding. Variations tend in both directions, yet 
center more or less around the 4-peck rate. The data do not con- 
_clusively point to any rate as best for any particular condition, but 
since farm practice is already based on the 4-peck rate of seeding the 
' experimental evidence at least does tend to confirm this practice. 
SPRING WHEAT. 
At Lind the experiments with spring wheat to determine the best 
rates and dates of seeding did not include the rate factor for any date 
other than the first. The date of first seeding in the spring was deter- 
mined entirely by seasonal conditions and durimg the experiments 
varied from March 12, in 1919, to April 3, in 1917. In any case the 
first seeding date was always the earliest date in the spring at which 
seeding could be done. The two later dates were at regular intervals 
of one month after the first. The results are given in Table 35.

These data point conclusively to the advantages of early seeding 
for spring wheat. 
_ The rate of seeding does not seem to be a particularly important 
factor so long as the rate is heavy enough to provide a stand capable 
of competing with weeds. The results of rate-of-seeding experiments 
with spring wheat are given in Table 36.

These data indicate that a rate of 4 pecks gives the best average 
net yield in the 5-year period, and considering the superior advan- 
tages of heavier stands in competing with weeds and wireworms a 
rate of 4 pecks or more probably is advisable.
