Abstract or Description: 
Summer slump is a decline in growth of alfalfa usually beginning in July in areas where maximum daily temperature exceeds 100 degrees F, such as the low elevation deserts of Southwestern U.S. In more temperate regions, there is a gradual decrease in alfalfa yield in successive harvests throughout the year, but the yield decline in the summer is not as sharp as in hot summer regions. The term summer slump has also been applied to reduction in growth of perennial cool season grasses such as tall fescue during the summer.
