WASHINGTON GROWN ALFALFAS 
HAVE RIGOROUS WINTERS 
States B. R. Bertramson, Chairman, Department of 
Agronomy, Washington State College 
A study of the weather records for the last five years 
shows that in the Yakima Valley, where the bulk of the 
state’s alfalfa seed is grown, temperatures each year 
have hit zero or below and on occasions dropped as low 
as 25 degrees below zero. In addition to these low 
temperatures in this basin area located between the 
Rocky Mountains and the Cascades, the low annual 
precipitation leaves the area little protected by winter 
snow falls. Hence the rigor of winter may be more 
keenly borne by these Washington alfalfas than in 
states where cold weather is accompanied by ample 
snow fall to give protection. Without a protective snow 
cover, the alternate freezing and thawing subject the 
Washington alfalfa to severe heaving. 100 lbs.
