Our objective is to analyze the behaviour of cereals at the level of soils characterized by different salinity rates, in Oranais and to see the correlation between the nature of the soil and the yield. We studied the regional bioclimate and carried out physicochemical analyzes of the soils of plots sown during the 2016-2017 agricultural campaign in durum wheat (Semito variety) and barley (Saida variety), at three sites. In particular at the CFPA (Professional Training and Learning center) of Misserghin in the Province of Oran, Si Zidane pilot farm in the Province of Sidi Bel Abbes and at the level of INRAA of H'madena in the Province of Relizane. Our study allowed us to identify variability in salinity,with extreme salinity at the level of the sebkha of Oran which is used as the benchmark for the extreme rate of salinity observed. Other physicochemical parameters, different from one site to another, were determined with a view to looking for correlations of other parameters with salinity. The Misserghin site stood out in terms of yields compared to other sites thanks in particular to its low salinity rate which is 1.73ds m-1 and a rainfall of 296 mm with better distribution. Followed by the site of the Si Zidane pilot farm in Sidi Bel Abbes, and then followed by the INRAA site which revealed a low yield, given the aridity with low cumulative precipitation, as well as its situation in a Semi-arid lower than warm winter. Barley adapted best relative to durum at all three sites.
