This experiment was conducted to study the effects of combined application of organic fertilizer and chemical fertilizer on the production performance， nutritional quality and economic benefits of different triticale （×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： 120 （A1）， 240 （A2）， 360 （A3）， and 480 kg·hm^-2 N （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 the fertilization treatments， when the combined application rate of organic fertilizer and chemical fertilizer was 360 kg·hm^-2 N， the average hay yield （8.36 t·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 triticale varieties， the comprehensive evaluation value of ‘Gannong 2’ triticale （0.60） was higher than that of ‘Gannong 4’ triticale （0.40）. Their interaction showed that when the combined application of organic fertilizer and chemical fertilizer was 360 kg·hm^-2 N， the comprehensive evaluation value of Gannong No.2 was the highest （0.84）， which was higher than that of the two triticale varieties under single application of chemical fertilizer （0.52， 0.72）. In conclusion， under dry climate conditions， to balance high-quality and high-yield forage as well as economic benefits， the recommended nitrogen application strategy is as follows： for ‘Gannong 2’ triticale， a combined application of organic fertilizer and chemical fertilizer at a rate of 240 kg·hm^-2 N is suitable； for 'Gannong 4' triticale， a single application of chemical fertilizer at 360 kg·hm^-2 N is appropriate.
