The morphological characteristics of plants are often influenced by their access to nutrients. The aim of this study was to evaluate the morphological changes of quinoa cultivars in response to the use macro and micro elements at Ahvaz Station of Khuzestan Agricultural and Natural Resources Research Center. The experiment was a factorial in a completely randomized design with three factors: application of triple superphosphate fertilizer at 4 levels (0, 50, 100, 150 kg / ha), foliar application of zinc sulfate in 3 levels (water without zinc sulfate (control)), zinc sulfate foliar application at concentrations of 4 and 8 g/L) and three cultivars of Quinoa (Giza1, Q26, Titicaca) in three replicates in cylindrical pots of P.V.C. The results showed that the simple and interaction effects of treatments had significant effects on plant height, first branch to ground level and panicle length at 1% probability level. Application of 150 kg. ha-1 triple superphosphate and zinc sulfate foliar at 4 g/L significantly increased morphological indices of quinoa cultivars. Also, among the cultivars studied, Q26 had the highest plant height, panicle length, stem diameter and root diameter.
