Effectiveness of a land imprinter and rangeland drill for establishing 'Nordan' crested wheatgrass (Agropyron desertorum) from fall plantings on loose and firm seedbeds was compared in the northern Great Basin in 1982 and 1984. Seedbed treatments applied on a Wyoming big sagebrush (Artemisia tridentata subsp. wyomingensis)-Thurber needlegrass (Stipa thurberiana) habitat type included brushbeating, brushbeating plus disking, and no treatment. Crested wheatgrass seed was planted at 6.7 kg/ha by broadcasting before imprinting broadcasting after imprinting, with a rangeland drill equipped with depth bands and at 3.4 kg/ha with a rangeland drill with deep-furrow openers. Maximum seedling emergence occurred on brushbeat-disked seedbeds planted by broadcasting before imprinting in 1982 (37/m2) and 1984 (22/m2) and by drilling with regular openers in 1982 (23/m2). Seedling emergence was almost twice as good with imprinting compared to drilling on loose-brushbeat-disked seedbeds, but 2 to 4 times more seedlings emerged from drilling than imprinting on firm-unprepared seedbeds. Maximum yields produced 2 and 3 years after planting averaged 500 to 1,000 kg/ha on brushbeat-disked seedbeds planted by broadcasting before imprinting and regular drilling. Imprinting may be a viable alternative to drilling in this region on loose seedbeds.
