Evaluation of Triticale Grain Yield and Quality under the Influence of Genotype and Fertilization on Acid Soil

Triticale, a hybrid of wheat and rye, is valued for its high yield potential, adaptability to marginal soils, and nutritional quality. Grain yield and quality are influenced by genotype, fertilization, and environmental conditions. Understanding the interactions among these factors is essential for optimizing productivity, especially on acidic soils where nutrient availability can be limited. In a two-year study, variations in grain yield, hectoliter weight and 1000 grain weight of triticale were investigated, depending on the genotype, fertilization and the year of the study. Genotype Triamo (G2) achieved the highest grain yield (6.50 t ha-¹) in the T5 treatment in the second year, compared to the control treatment (3.66 t ha-¹), with a significant factor interaction (p<0.05). The hectoliter weight was the highest in the Triamo genotype (65.80 kg hL-¹) in all treatments, while the Odisej genotype in the first year in the T5 treatment had the highest of 1000 grain weight (48.20 g). The correlation between grain yield and hectoliter mass was positive (r=0.44**), while between grain yield and 1000 grain weight, a weak negative relationship was established (r=-0.03). The results indicate the importance of an optimal combination of genotype and agrotechnical measures in order to achieve optimal yields and quality of triticale grains on acidic soils.
