The relative boron tolerance of three varieties of tall wheatgrass [ Agropyron elongatum (Host) Beauv.], ‘Alkar,’ ‘Largo,’ and ‘Nebraska P. I. 98526,’ grown in nutrient cultures was determined. Alkar was also tested in soil cultures. Boron concentrations responsible for a 50% decrement in growth in nutrient cultures ranged from 33 to 38 ppm water‐soluble B for the three varieties. The B level causing a 50% decrement in growth of the Alkar variety in the soil culture was 46 ppm water‐soluble B in the soil solution.
