Abstract
The present study was carried out at Experimental Farm of faculty of Agriculture, Saba Basha, Alexandria University, Abess, Alexandria, Egypt, during the two seasons of 2018/2019 and 2019/2020 to study role of organic manure, salinity remediator and selenium and their interactions for alleviating the effect of salinity on yield of barley (Hordeum vulgare L. cv. Giza 123). The preceding crop was maize (Zea mays L.) in both cropping seasons. Soil samples of the experimental sites were taken at the depth of (0-60 cm). This experiment was conducted in split- split plot design in three replications during the two seasons. The main plots was organic manure (Without application (control), 12 and 24 m3), subplot was application of salinity remediator (control, Agrosol Tonic at the rate of 12 l/ha with the first irrigation, Agrosol Tonic at the rate of 12 l/ha with the second irrigation) and foliar application of Na selenite rates (spray water, 5 ppm and 10 ppm) was distributed in sub- sub plot in both seasons.
