    On the application of arabian gulf water in irrigation: A future possibility حسب Abu Sharar, Taleb [طالب ابو شرار]

    منشور في 1987
    "…Barley can tolerate 12 dS m water salinity without any apparent yeild decrement. Yield would decrease by 5% per each additional increment in water salinity beyond 12 dS m Thus, if Gulf water salinity was treated according to the model of plant response to time weighted salinity, then barley could alternatively be irrigated with fresh/Gulf water in a way that would save a minimum of 16% of the applied water. …"
