The principle is equally important for all
countries where dry-farming is practiced.
Other small grains
_Oats _is undoubtedly a coming dry-farm crop. Several varieties have
been found which yield well on lands that receive an average annual
rainfall of less than fifteen inches. Others will no doubt be
discovered or developed as special attention is given to dry-farm
oats. Oats occurs as spring and winter varieties, but only one
winter variety has as yet found place in the list of dry-farm crops.
The leading; spring varieties of oats are the Sixty-Day, Kherson,
Burt, and Swedish Select. The one winter variety, which is grown
chiefly in Utah, is the Boswell, a black variety originally brought
from England about 1901.
_Barley, _like the other common grains, occurs in varieties that
grow well on dry-farms. In comparison with wheat very little seareh
has been made for dry-farm barleys, and, naturally, the list of
tested varieties is very small. Like wheat and oats, barley occurs
in spring and winter varieties, but as in the case of oats only one
winter variety has as yet found its way into the approved list of
dry-farm crops.
