Abstract
The influence of irrigation with saline water on the seed yield, oil content, and quality of stock (Matthiola incana), an oilseed plant rich in omega-3, was studied under greenhouse and field conditions as part of a study to assess the potential of stock to replace low cash field crops in areas of marginal water use due to water scarcity. Water of electrical conductivity ≤6 dS/m did not have a negative effect on yield parameters. Total yield, seed number, and oil content were not affected by salinity, whereas the content of omega-3 was significantly increased.
Additional keywords: salinity, seed oil, omega-3.
