The effect of elevated Temperature was studied on the accumulated total dry weight and the amount of uptake nutrients from emergence to anthesis in durum wheat. The elevated temperature reduced the dry weight of the plants by an average of 12.6% and absorbed N, P and K by an average of 19.3%, 21.3% and 12.9%, respectively. The higher temperature reduced content of the Fe (12.4%), Mn (13.1%), Cu (14.9%) and Zn (16.2%). Genotypic specificity was proven in durum wheat under the effect of elevated temperature. Variety Vazhod demonstrated most susceptibility to future temperature changes. In this genotype elevated temperature was decreased by 17% aboveground dry weight in anthesis and by 30% the amount of N and P in the plants.
