Abstract：This experiment was conducted to study the effects of combined application of organic fertilizer and chemical fertilizer on the production performance，nutritional qualityand economic benefitsof diferent triticale （x） Triticosecale） varieties，and to provide theoretical basis for high yield cultivation techniques of triticale in dry farming areas of central Gansu. The experiment used a split-plot design，and the main plot factor was nitrogen application rate，which was set at four levels：12O（A1），24O（A2），360（A3），and 480kg⋅hm-2N （A4）. For these nitrogen application treatments，nitrogen was applied as a combination of organic fertilizer and urea，with 2/3 of the nitrogen from organic fertilizer used as base fertilizer and 1/3 from urea as topdressing. Two control treatments were also included：no fertilization（CK1） and single application of chemical fertilizer（CK2）.The subplot was two triticale varieties （C1：‘Gannong No. 2∙ ；C2：‘Gannong No. 4′ ）.The results showed that among thefertilization treatments，when thecombined applicationrateoforganic fertilizer and chemical fertilizer was 360kg⋅hm-2N ，the average hay yield （8.36t⋅hm-2， ），crude protein content （10.73%） ，and comprehensive evaluation value （0.95%） ）of the two triticale varieties were relatively higher. From the perspective of triticalevarieties，thecomprehensiveevaluationvalueof‘Gannong 2∙ triticale（O.6O）washigherthanthat of‘Gan nong 4′ triticale（O.4O）. Their interaction showed that when the combined application of organic fertilizer and chemical fertilizer was 360kg⋅hm-2N ，the comprehensive evaluation value of Gannong No. 2 was the highest （0.84），which was higher than thatof the two triticale varietiesunder single application of chemical fertilizer （0.52，0.72）.Inconclusion，underdryclimateconditions，to balance high-qualityand high-yield forage as well as economic benefits，the recommended nitrogen application strategy is as folows：for‘Gannong 2∙ triticale，a combined application of organic fertilizer and chemical fertilizer at a rate of 240kg⋅hm-2N is suitable； for 'Gan- nong 4′ triticale，a single application of chemical fertilizer at 360kg⋅hm-2N is appropriate.
