Abstract

The research was conducted in the Natural Resources Research Department/Homs Research Center, for three consecutive seasons 2015/2016, 2016/2017, 2017/2018, with the aim of knowing the response of two soft wheat cultivars to several levels of supplementary irrigation and several levels of nitrogen fertilizer. Two soft wheat cultivars (Bohouth10 and Douma6) were planted in a split-split-plot design experiment, with three irrigation treatments (100%, 66%, 33%) of the water requirement with a control without irrigation (rainfed), and five nitrogen fertilization treatments (N0: fertilizer recommendation, N1, N2: 25% and 50% higher than fertilizer recommendation respectively, N3, N4: 25% and 50% lower than fertilizer recommendation respectively), with three replicates for each treatment. The results showed that the 100% irrigation treatment was superior in terms of water requirement with a grain yield of 5.67 tons/ha over the other treatments, while the differences were apparent between the varieties, with a grain yield of 4.18 and 4.13 tons/ha for the Douma6 and Bohouth10 varieties, respectively. As for the differences between the fertilizer treatments, they were apparent with a grain yield of (4.14, 4.22, 4.29, 4.14, 3.99) tons/ha for the N0, N1, N2, N3, and N4 fertilizer treatments, respectively.
