The experiment was carried out during the two seasons 2019/2020 and 2020/2021 at the Hamima Research Station, east of Aleppo Governorate, with the aim of determining the best need for nitrogen in the growth and productivity of irrigated wheat (Doma1), The transactions in the following form where the treatment of the recommendation: (N0: without addition, N1: 70, N2: 105, N3: 140, N4: 175, N5: 210 and N6: 245) kg N/he. Two treatments were were less than the recommendation with a rate of (25, 50)%, and three treatments were higher than the treatment of the recommendation with percentages (25, 50, 75)%, in addition to the treatment of the control (N0). The experiment was carried out by designing randomized complete sectors with three replications. The results showed a direct increase in the values of morphological traits with an increase in the rate of urea fertilizer added to the soil compared with the control, and the treatment N5 outperformed the rest of the treatment for the productive traits in both seasons.

Keywords: Urea, Wheat (Doma 1), Morphological and Production traits.
