الملخص EN

The study was conducted at the research station of Field Crops Department - College of Agriculture - University of Tikrit during 2017 - 2018.

Three levels of Nano Zinc (0 _50_100 ppm) were sprayed on ten Genotypes of Tritium durum (Baghdad(1) , Fadda48 22(2) , Simeto cheak 38(3), Lahnau Cam 47(4) , Amedakwl 15(5) , Mau ssara 10(6) ,Bijah Sia 17(7) , Sardar 36(8) , Halio 26(9) and I Carasha 45(10) ).

Studied traits were days to (75%) heading, flag leaf area, plant height, number of spikes per m2 , number of grain per spike, 1000 grain weight and grain yield, biology yield and harvest index.

The results of the study were summarized and showed significant differences among concentrations of Nano Zinc and Genotypes and interaction for all characteristics.

The best interaction was between 100 ppm and I carasha 45 in spikes number /m2 , total seed yield and biology yield which give (517.50 spikes per m2 , 6.210 tn.ha-1 and 20.550 tn.ha-1 respectively.
