Water conservation is essential in the West. In addition, there is an increasing desire for naturalized landscaping. To meet these needs in the sod industry, we are investigating various aspects of sod production using native and adapted grasses. Eighteen different monocultures or mixtures of native and adapted grasses were seeded in the spring of 2006. The species used include buffalograss, blue grama, western wheatgrass, streambank wheatgrass, crested wheatgrass, sheep fescue, Canada bluegrass, sandberg bluegrass, and muttongrass. Some of the mixtures had warm season grasses seeded in the spring and then overseeded with cool season grasses in the fall. Kentucky bluegrass was used as a control. Netting was used as a second treatment in a factorial design. The plots were then evaluated for quality, percent cover, and species composition throughout 2006 and 2007. Sod will be harvested from these plots in early summer and late summer of 2007 and evaluated for sod strength and ability to transplant. All maintenance such as mowing (3.5 inches) and fertilizing (3 pounds of N per 1000 sq. ft.) was performed at sod production levels, i.e. non-limiting.
