Planting season and cultural treatment effects on emergence and survival of three range species were determined for two cold, dry pinyon-juniper sites in north central Arizona. Plowing was the most effective seedbed preparation for controlling plant competition. Furrow drilling also eliminated a large amount of competition. Emergence and survival (E & S) of Luna pubescent and Nordan crested wheatgrass averaged highest with fall planting, but summer planting was best for E & S of fourwing saltbush. E & S averaged highest on plowed seedbeds and decreased progressively on undercut, undercut-strip, presprayed, sprayed, and control seedbeds. Surface drilling on tilled seedbeds increased E & S over furrow drilling for fourwing saltbush and usually for Nordan crested wheatgrass. Drilling in wide, shallow furrows increased Luna pubescent wheatgrass E & S. Furrow drilling increased E & S for all species on nontilled seedbeds. There were some significant interactions among treatment combinations. Practical application of results is discussed.
