Technical Abstract: Common purslane is traditionally considered a weed. Recent literature suggests the potential human health benefits of omega-3 fatty acid consumption. Omega-3 fatty acids are found in flax seed oil (LNA) and fish oil (DHA and EPA), but the highest known producer of Omega-3 fatty acid in plant tissue is common purslane. In order to produce common purslane for seed and as a potentially healthful forage for chickens, goats, cattle or humans, we need to explore herbicide options and harvest strategies. Studies were conducted on a taller, upright growing variety of common purslane the summer of 2006 at the Central Great Plains research station. Herbicide screens were conducted in the greenhouse and desiccation trials were conducted both in the greenhouse and the field. Preliminary findings such as biomass production, yield data, and crop tolerance will be discussed.
