The present study was conducted to determine the effect of variety, organic fertilizer and predecessor on protein, lysine and methionine contents, and their variation in triticale grains under biological cultivation. During the 2014-2017 period, a three factors experiment was managed on field certified for organic farming in Field Crops Institute - Chirpan, Bulgaria. Three varieties, three doses of organic fertilizer and two predecessors (sunflower and durum wheat) were tested. Based on the data obtained, it was found that the variety has a significant influence on the parameters studied. The highest significant values of the chemical parameters were observed when applying organic fertilizer at a dose of 1,750.0 kg/ha. After a predecessor of durum wheat, the value of lysine was higher and statistically significant compared to predecessor of sunflower. Similar coefficients of variation of the studied parameters were found, which not depended of a variety, a predecessor and an applied organic fertilizer, varying between 4.38% and 5.35% for protein, 4.1% and 5.33% for lysine and 4.31% and 5.22% for methionine.
