In a field experiment, conducted during the period 2016-2018 year on the experimental field of the Crop Science Department at the Agricultural University of Plovdivare investigated the content and yield of crude and digestible protein in triticale grain under the influence of the treatment with plant stimulants and different fertilization levels. The experiment was carried out according the block method in four replications after predecessor sunflower and plot size of 15 m2. There were used three triticale varieties Kolorit (standard), Musala and Trismart and two fertilization levels N6P5K2 and N12P10K4.The treatment with the plant stimulators Vitafer Algi (VA) and Vitafer Green (VG) was performed in the beginning of stem elongation (BBCH 31).The present study determined that combined treatment with plant stimulants and increased fertilization rates resulted in a 4-5% increase in crude protein yield and up to 1.6% in the amount of digestible crude protein compared to the lower fertilization level.

During the period 2016-2018 year on the experimental field of the Crop Science Department at the Agricultural University of Plovdiv a field experiment was carried out according the block method in four replications with three triticale varieties Kolorit (standard), Musala and Trismart after predecessor sunflower and plot size of 15 m2. The action of the plant stimulators Vitafer Algi (VA) and Vitafer Green (VG) was conducted under two different nutrition regimes of the soil: N6P5K2 and N12P10K4. The plant stimulators were applied in the beginning of stem elongation (BBCH 31). The aim of the study was to determine the influence of the applied nutrition regime and the treatment with plant stimulators on some yield components: plant height (cm) and tillering. From the dispersion analysis we can conclude that the fertilization is a major factor that most influences the studied yield components plant height, number of tillers per m2, number of stems per m2 and percentage of productive tillering, as the differences between the different variants are significant and statistically proven for the two-year study period. Second in importance is a factor variety, followed by the factor treatment with plant stimulants. Average for the two-year period of the investigation the application of the plant stimulants leads to 1.03 to 1.07% increase in the examined parameters according to the untreated variants, as by number of tillers per m2 number of stems per m2 and plant height the best results are achieved with VG and by the percentage of productive tillering, VA achieved the best effect.
