CEREAL EXPERIMENTS AT JUDITH BASIN SUBSTATION. 13 
TREATMENT OP CROPS. 
The seeding has been done with an 8-foot double-disk and a 6-foot 
single-disk drill. On each drill the spouts were 6 inches apart. After 
seeding no cultivation has been given the plats. In some years it 
was necessary to cultivate the alleys and roads in order to kill the 
weeds. In the 18-inch alleys between the fiftieth-acre plats the 
weeds are pulled by hand, and no cultivation is necessary. 
Harvesting is done with a binder. The grain is shocked on the 
plats and remains there until it is thrashed. The thrashing is done 
with a small thrasher with a 26-inch cylinder. Since the varieties 
have been grown in the replicated plats, one plat of each variety has 
been carefully rogued and the crop from this plat thrashed in the small 
nursery thrasher. By this method it is possible to avoid the mixture 
that takes place in the larger thrasher and thus obtain pure seed of 
each variety. 
CROP RECORDS. 
The first notes taken after sowing are on the date of emergence. 
After this, notes are taken on the stand of the different varieties. 
Since all the varieties of any one cereal are seeded at the same rate 
and on the same date all stands are usually uniform, but any differ- 
ences are noted. Any disease that may appear is noted, as is also 
the percentage of lodging. Records are kept of the dates of heading, 
ripening, and cutting of each variety. 
Nursery Experiments. 
The new varieties tested in the nursery are usually grown in 3-rod 
or 8-rod rows, depending on the quantity of seed available. In some 
cases it is possible to discard some of the varieties the first year, but 
usually they are grown two years. By that time it is possible to dis- 
card the poor varieties, while the most promising ones are increased. 
In the improvement experiments the starting point is usually the 
head row. From the head row the good selections are grown in 3-rod 
or 8-rod rows, depending on the quantity of seed available. After 
being tested in 8-rod rows for two years it is usually possible to dis- 
card the poor selections. The more promising ones either are 
increased or continued in 8-rod rows. When they are increased they 
are usually grown in a hundredth-acre or fiftieth-acre plat for one 
or two years before being grown in the regular varietal test. 
The selections in head rows are sown by hand. In all the other 
nursery work the seeding is done with a grain drill. In seeding the 
3-rod and 8-rod rows alternate holes in the drill are closed and the 
rows sown 1 foot apart. The rows are harvested by hand and 
thrashed in the nursery thrasher. Complete notes are taken on all 
selections and varieties.
