Abstract
The experiment was conducted in fields of field crops department-agriculture college / Al-qasim green university in winter season 2018-2019, the field ground was tilled, smoothed and modified, The field was divided according to Randomized Completely Block Design with three replications, the plots were included five treatments from division of the N fertilizer : N0 : without addition, N1 : 1/2 at planting- 1/2 at stem elongation, N2 : 1/4 at planting -1/2 at stem elongation â 1/4 at booting, N3 : 1/3 at planting - 1/3 at stem elongation -1/3 at booting and N4 : 1/4 at planting - 1/4 at stem elongation - 1/2 at booting, 825 triticale cultivar was used with seedling rate 100 kg.h-1 in lines planting at distance 20 cm among lines, the weeds were removed, the study traits were : plant height - No. of grains. spike-1 - grain 1000 weight- grains yield â percentage of proteins. The results showed that the treatment N4 gave high value while the treatment N0 gave less value in plant height, the high mean in grain 1000 weight found in treatment N4 comparison with treatment N0 which gave value, the treatment N4 also gave higher grain yield in plant while the treatment N0 gave lower value in plant. The results appeared variation in percentage of protein, the treatment N4 gave high value comparted with the treatment N0 which gave low value.
