Table XIII shows that the average yield of plats sown October 1 
and October 15 is from 10 to 11 bushels per acre less than that of 
plats sown September 1 to 7. 
In all the varietal tests at the Judith Basin substation an effort 
has been made to sow winter wheat early : that is, between August 10 
and September 10. In 1908, the only year when there was much 
winterkiUing, the seeding was late because the seed was not available 
earlier. 
Rate-of-Seedixg Experiments. 
E at e-of -seeding experiments with winter wheat were started in 
1909 and conducted for six years. During the first three years, the 
Turkey (C. I. No. 1558) was used, while during the last three years 
the Kharkof (C. I. No. 1583) was sown. The rates of seeding ranged 
from 2 to 8 pecks per acre. Table XIV contains the data that have 
been obtained from these tests. This table shows that there is but 
little difference in the yields produced from the 3-peck and the 4-peck 
rates of seeding, the rates from which the highest yields have been 
obtained. 
Because of the free tillering of winter wheat it is not necessary to 
seed heavily in order to get a good stand. Seeding more than 4 pecks 
to the acre not only reduces the yield but also the quality of the grain. 
Three pecks is the rate usually sown by farmers in the Judith Basin 
and is the one at which all of the plats in the varietal tests are sown.

SPRING WHEAT. 
Spring wheat is not as important a crop in Montana as whiter wheat. 
In the Judith Basin the acreage of spring wheat is very small hi com- 
parison with that of winter wheat. In the eastern part of the State, 
where winter wheat is not a sure crop, spring wheat is of more 
importance. 
The work with spring wheat at Moccasin has included field plat 
and nursery tests. The varieties tested have included those that 
have given the best results in other dry-land districts of the Great 
Plains area.
