CEREAL EXPERIMENTS AT THE WILLISTON SUBSTATION. yal 
It will be seen that in none of the years was there any significant 
difference between the results from the seedings at 4, 5, and 6 pecks. 
The results from the 3-peck seeding are sufficiently lower to show 
that 3 pecks is not enough. Since the 4-peck rate gives as good re- 
sults as the sowing of 5 or 6 pecks and requires less seed per acre, it 
should be considered the proper rate. The general practice of the 
farmers in the vicinity of Williston is to sow 4 pecks to the acre. 
“Tn each of the years the plat on which the 3-peck rate was seeded 
was more weedy throughout the season than the plats where the higher 
rates were used. Owing to the thinner stand of wheat plants in the 
3-peck rate, the time from planting to maturity was several days longer 
each year. The bushel weight of the grain also wasless. The average 
weights per bushel of grain were 56, 553, 55, and 53} pounds from 
the sowings at 6, 5, 4, and 3 pecks, respectively. 
NURSERY TESTS OF SPRING WHEAT. 
Table X presents certain nursery data for 84 races in the different 
groups of wheat. These were grown in the 174-foot rows, planted 
each year with the planter that placed 210 seeds 1 inch apart in the 
row. These data are averages for the two years, 1912 and 1913. 
The same races were used in each of the two years. 
- The season of 1912 was a very good one for crop production. The 
rainfall was above normal for the growing period, April to July, in- 
clusive. The season of 1913 was the reverse of 1912. It was exceed- 
ingly dry until the latter part of June, and the rainfall from April to ; 
July, inclusive, was considerably below normal. —

In the durum races, as shown by Table X, there were 30 with 
glabrous and 9 with pubescent glumes. Those with smooth glumes, 
which include the races of Kubanka and Arnautka, produced the best 
average yield of grain, 311 grams, compared with 274.1 grams per row 
from the pubescent-glumed races. The straw also was longer and 
heavier and the heads longer. The number of tillers, the length of 
_ heads, and the kernel weight were lower in the smooth-glumed than in 
the hairy-glumed races.
