FALL-SOWN OATS IN THE SOUTH 13 
of different strains have been grown in the nursety experiments. 
However, only a relatively small number of all these strains have been 
of sufficient promise to warrant their continuance over a period of 
years. 
NURSERY METHODS 
Prior to 1913 only single or duplicate rod rows of each strain were 
grown. ‘These tests were largely preliminary, and the data obtained 
are not presented in this bulletin. Beginning with 1913 and con- 
tinuing up to and including 1920, most strains were grown in tripli- 
cated single-rod rows, with every tenth row sown to the Culberson 
variety as a check. Since 1921 the best of the different varieties and 
selections grown in the oat nursery have been sown in duplicated 
three-row blocks or plots. Check plots are no longer used. When 
sown the rows are 18 feet in length, but at harvest they are reduced 
to 15 feet by discarding 1)4 feet from each end. Approximately 100 
laa? are grown in the duplicated three-row block nursery each 
year (8). 
The average yields obtained during the eight-year period from 1913 
to 1920, inclusive, together with the annual and average yields ob- 
tained during the five-year period from 1921 to 1925, inclusive, from 
a number of varieties and selections of fall-sown oats grown in nursery 
rows and plots at the Arlington Experiment Farm are given in Table 4.

1 The lower average yields for the period from 1913 to 1920, inclusive, in part at least were due to severe 
injury by winterkilling in 1915 and 1920.

3 Average for the period from 1915 to 1920, inclusive.
