Özet:

This research was carried out under Isparta conditions in 2018-2019 vegetation period. In the study, 2 durum wheat (Çeşit-1252 and Kızıltan-91) and 2 triticale (Ümran Hanım and Karma-2000) varieties were used. In this research; the effect of different nitrogen fertilizer applications (nitropower 33 and dinitroso) on some mineral contents (Fe, Zn, Phosphorus, K, Mg) in different development stages was investigated. This research was consisted of 24 plots (2 nitrogen applications x 4 varieties x 3 replications = 24) and carried out split split plot design with three replications. 550 seeds were sown on per square meter and 7 kg P2O5 and 5 kg / da N were applied to all plots during planting. The other half of the nitrogen was given at the beginning of stem elongation period. In research results, in the early harvest period while the values of Mg, P, Zn, Fe contents decreased, K ratio increased. In slow release fertilizer (Dinitroso) application some nutrient contents (Fe, P, K and Mg) have increased significantly. As a result; It has been determined that triticale can be used for freekeh purposes as it is harvested early and slow release fertilizer application has been determined to be effective on grain quality.
