Abstract: The straw yield and agronomic characteristics of recommended spring wheat, oats, and barley cultivars were compared at Hartland, New Brunswick in 1999 and 2000. The straw yields ranged from 2.51-3.31, 2.73-3.68, 2.28-3.63, and 2.69-3.59 T/ha for spring wheat, oats, six-row barley, and two-row barley, respectively. Plant height ranged from 85-96, 103-110, 73-99, and 78-94 cm, respectively for spring wheat, oat, six-row barley, and two-row barley. Stem population per m2 ranged from 402-520 for spring wheat, 315-455 for oats, 387-516 for six-row barley, and 529-714 for two-row barley. There appears to be little correlation between straw yield, plant height, and head population for spring grains. There is an indication that higher stem populations per m2 can contribute to higher straw yields when comparing two-row and six-row barley.
