Abstract The field experiment was conducted to study the effects of γ -polyglutamic acid and nitrogen（N） on the agronomic traits，yield， quality and nitrogen use efficiency（NUE） of sesame.The results showed that the combination of γ -polyglutamic acid and different N rates increasedthe plant heightand fruit axis length ofsesame，reduced the sputumpositionand theyelowtips，and increased by 7 . 5 % - 1 7 . 2 % and （20 1 7 . 5 % - 3 5 . 7 % for the 1O0-grain weight andthe yieldof sesamerespectively；the sesamequality（such as oil content，protein，sesamin and sesamolin） at the N application were better compared to γ -polyglutamic acid application. There was no significant difference in sesame quality between the application of 120 and . Increased N application rate increased the N fertilizer contribution rate and N agronomic utilizationrate，utdreasedteUEndartalprductivityeNUE，silavlablendlableKontentreicreasduderhlica tion of γ -polyglutamic acid. Considering the synergistic effect of arsenic nitrogen fertilizer and γ -polyglutamic acid，the effect of the combined with γ -polyglutamic acid application was better，can be applied in sesame production.
