During the 2014-2016 period, in the experimental field of the Department of Plant Growth at Agricultural University of Plovdiv were carried out field experiments. The aim of the study was to investigate the influence of foliar fertilizers on the chemical composition of the grain of durum wheat varieties Predel and Elbrus. The plants were treated in the tillering, jointing and heading phases of growth with Megafol (300 ml/da) and Megafol-protein (300 ml/da). The results were compared with an untreated control. The experiments were based on a predecessor chickpea on the block method in four replications with a plot size of 15 m2. As a result of the experiments, the use of Megafol-protein had the most significant effect on the crude protein content of the Predel grain when it was applied in the tillering phase and the Elbrus grain when applied in the heading phase. The use of Megafol had a significant positive effect on the gluten content of the Elbrus variety only after application in the jointing phase.
