Dry Farming In Colorado

Badly injured by hail, but the silo will save what’s left 
seed or grain which is well adapted for feeding purposes. The 
sorghums have one very valuable characteristic—in drouthy pe¬ 
riods they will cease growth and unless the drouthy period is ex¬ 
ceedingly prolonged, will recover and continue growth if moisture 
comes later. The sorghums have a very large place in the forage 
crops of our dry-land regions because of their ability to with¬ 
stand drouth. They cannot be successfully grown in some local¬ 
ities, because of the cold climate resulting from the high alti¬ 
tudes. Where the sorghums will out-yield corn, they should be 
grown for forage purposes in preference to corn. 
Forage Sorghums or Sorgos .—The forage sorghums can be 
grown practically all over the Colorado plains. In some localities 
near the foothills and in some localities on the Platte-Arkansas 
Divide, the altitudes are too high and the climate too cool for the 
best development of even the shortest-season sorghums. 
There are a large number of varieties and types of sorghums. 
Practically only two types are adapted to any of our legions. 
These are the ambers and Sudan Grass. Of the ambeis we have 
Black Amber, Red Amber, and White Amber. 1 he White Amber 
was produced by selection by Mr. Freed, of Western Kansas. It 
is called in many sections, and in some government liteiatuie, 
“Freed’s Sorgo”. 
Sudan Grass is not commonly called a sorghum, but for the 
purpose of this bulletin, it can be classed with the sorghums. It 
crosses readily with the ambers or other sorghums, showing its 
close relationship.
