The application of various chemical products for plant protection and plant biostimulans increases financial costs, which is a prerequisite for their combined application in tank mixtures. During 2021 and 2022 on the experimental field of the Agricultural University of Plovdiv, Bulgaria, a field experiment with the rye variety “Milenium” was performed. The aim of the trial was to study the application of plant protection products in tank mixture with biostimluant and its influence to the rye grain yield and quality. The trial included the following treatments: 1. Untreated control; 2. Granstar 75 DF - 15 g ha-1 (herbicide); 3. Granstar 75 DF - 15 g ha-1+ Zantara 216 EC - 1.25 l ha-1 (fungicide); 4. Granstar 75 DF - 15 g ha-1 + Amino Expert Impuls - 3.00 l ha-1 (biostimulant); 5. Granstar 75 DF - 15 g ha-1 + Zantara 216 EC - 1.25 l ha-1 + Amino Expert Impuls - 3.00 l ha-1. The highest rye grain yield, absolute and hectoliter seed mass, grain wet gluten and crude protein for treatment 5 were recorded.
