Abstract: Straw yield and other agronomic characteristics of spring wheat, oats and barley were compared at Hartland, N.B. in 1999. Straw yields ranged from 8.50-7.19, 6.79-5.69, 7.18-5.69 and 8.42-6.34 T/ha for spring wheat, oats, six-row barley and two-row barley respectively. Plant height ranged from 79-88, 98-107, 66-94 and 72-93 cm respectively for spring wheat, oats, six-row barley and two-row barley. Head population per meter squared ranged from 552-372 for spring wheat, 488-275 for oats, 539-341 for six-row barley and 763-528 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 head populations can contribute to higher straw yields when comparing two-row and six-row barley.
