Abstract: In order to obtain higher yield and better quality for feed of “Dongnong96026” in Harbin of Heilongjiang Province, we start the study base on the density and nitrogen fertilizer and using Split-plot design. Through four plant densities treatments(7.5million basic seedling per hectare, 6million basic seedling per hectare, 4.5million basic seedling per hectare, 3million basic seedling per hectare) and three N fertilizer application levels(75kg/hm2, 150kg/hm2, 225kg/hm2), we studying the effect of density and N level on yield and feeding quality of triticale. The result indicated that lower density and higher N level were beneficial to biological yield and feeding quality. The best quality was found in this treatment of 4.5million basic seedling per hectare and 150kg/hm2.
