NURSERY EXPERIMENTS. 
The nursery experiments with barley consisted almost entirely of 
tests of varieties. No promising varieties not already being grown 
in plats were observed in the nursery experiments. Progenies from 
a few natural hybrids of barley found in the plats at Newell were 
grown for observation. The strains isolated were not as promising 
as other varieties previously mentioned. 
RATE-OF-SEEDING EXPERIMENTS. 
Kate-of-seeding experiments with White Smyrna barley, C. I. No. 
658, w T ere begun in 1917 and conducted for three years. The barley 
was sown at four different rates, ranging from 4 to 10 pecks per acre. 
The data are not entirely conclusive, but are of considerable interest. 
The yields are shown in Table XXIV. 
The highest average yield was obtained from the plats sown at the 
rate of 4 pecks per acre. In 1917, however, the 8-peck rate gave the 
highest yield. The barley in the varietal experiments usually has 
been sown at the rate of 5 pecks per acre, and from the average re- 
sults shown in Table XXIV this rate appears to be ample. On a 
well-prepared seed bed the sowing of 4 pecks of clean barley seed 
per acre apparently is sufficient.
