Wheat and Barley Variety Demonstration - 1986 - TLM Farms - Yuma, AZ

Abstract

On farm variety demonstrations are conducted by the Cooperative Extension Service to demonstrate the commercial potential of new and established varieties of wheat and barley when grown under various environmental and management conditions. As part of an ongoing variety demonstration program conducted in Yuma County, Arizona for the past 20 years, this study was conducted at TLM Farms on the south Yuma Mesa on extremely coarse-textured sandy soils under sprinkler irrigation. Five hard red spring wheat, six durum and four barley varieties were evaluated under TLM Farms management using 13 ft x 275 ft randomized plots with four replications. Statistically significant yield differences were measured that suggest, when compared to previous and other studies, that variety performance on coarse textured, sprinkler-irrigated soils is different than on finer textured flood-irrigated soils.
