AbstractRomaine lettuce plays an important role in Yuma’s economy. An estimated 10,000 acres are cropped to large number of varieties each year with planting season that spreads from September to March. The demonstration site was selected to compare new and existing varieties of romaine lettuce on growers’ fields using standard farming practices. Selected growth parameters were evaluated throughout the growing season. Results indicate that varieties tested at Barkley Farms in Yuma are expected to do well if grown under similar growing conditions and planting time. Varieties tested during this planting slot did not experience any incidence of diseases. There was no significant head size and head weight difference among varieties evaluated. Number of heads per bed and number of heads left after harvest were significantly different among varieties tested.
