Abstract: 

A field experiment was conducted at the Al-Sfireh Region in Aleppo using a completely randomized block design RCBD with three replicates. The search aimed to study the effect of soil application and foliar application by Zn’s chelate concentrations on the production of durum wheat variety Douma 1 and the content of Zn in soil, grain and straw through two seasons (2019/2020 and 202/2021). The treatments were foliar application of Zn by concentration (100, 150 ppm) and soil application by (150, 200 ppm) twice at tillering and spike heading, with control (without fertilizer). Results showed significant differences and superlatives of all fertilized treatments compared with control at all traits (soil, straw and grain content of Zn, thousand kernel weight and grain yield). The effect of methods of applications differs on grain yield from season to season. All foliar application treatments had superiority on soil applications for most traits. The grain yield increasing upon adding methods by 150 ppm ranged between 9.7-10.6% in foliar application compared with soil application
