Abstract: 

A field experiment was conducted in Abe Jarash Farm at the Faculty of agriculture affiliated with the University of Damascus, during the growing seasons (2020/2021), in order to evaluate the response of four barley cultivars (Arabic white, Arabic black, Furat-3, Furat-6) for the fertilizer in four different levels of nitrogen fertilizer (T1:without fertilizing،T2: N80،T3: N100،T4: N120) kg.h^-1depending on some Morphological and Productivity Traits associated with improving the grain yield. The experiment was carried out according to split plots design in three replicates. The results showed significant differences among mean values of studied parameters, where barley cultivar Furat-6 recorded significantly highest mean values under  level of fertilizer N120 kg.h^-1 , In leave area index , number of spikes / plant ,weight grains / plant, number of grains/plant , and grain yield (5.65, 12.56 spikes.plant^-1,9.25  g, 194.5grains.plant^-1,  3450kg.h^-1 respectively) as compared to barley cultivar  Arabic black which recorded lowest mean values under zero fertilizer level (2.06, 3.62 spikes.plant^-1, 2.50g, 52.50 grains/plant^-1, 2750 kg.h^-1 respectively). study indicates the importance of using mineral fertilizers at an average rate (N120 kg.h^-1) and (N100 kg.h^-1)  in order to improve the productivity of barley crops under  Damascus city conditions.

Keywords: barley, cultivar, fertilizer, Yield.
