Abstract
Salinity is one of the most important problems that agriculture faces in the arid and semi-arid areas. That was motivated us to look at one of its aspects, which is irrigation water salinity, but with organic matter amounts to reduce the deterioration caused by this kind of water, and to come out with the right doses of organic matter at different levels of irrigation water salinity. We have applied three levels of irrigation water salinity: S1= 5 dS m-1, S2= 9 dS m-1 and S3=13 dS m-1, with three organic matter doses: F0= 0 t/ha, F1= 30 t/ha and F2= 60 t/ha. The results obtained were very encouraging and important through the noticeable impact of the measures studied. The positive impact of organic matter amounts on the saltiest treatments has been manifested, unlike the less salty treatments that they lack and we can say that the dose of 60 t/ ha of poultry manure is the best to increase the production of grains yield and straw yield, but the dose of 30 t/ha is the optimal dose to increase the weight of 1000 grains. This confirms the effectiveness of it responding to the irrigation water salinity effects, which is manifested in better plant yield.
