Abstract
Research was conducted in a greenhouse at Bozeman, Montana and on coal mine spoils at Colstrip, Montana [USA] in 1975 to determine the initial establishment of fairway crested wheatgrass (Agropyron cristatum), critana thickspike wheatgrass (A. dasystachyum), ranger alfalfa (Medicago sativa) and fourwing saltbush (Atriplex canescens). Establishment of the 4 spp. in the greenhouse experiment was different from that in the field experiment. In both studies all 4 spp. showed good initial establishment. N and P fertilizer application after emergence had no effect on the survival of any species.
