THE INFLUENCE OF THE VARIETY AND DIFFERENT DOSES OF NITROGEN ON THE GRAIN YIELD AND PROTEIN CONTENT IN TRITICALE GRAIN

Abstract

Observed through agronomic and economic significance, cereals represent the most important group of field plants, and the protein content in grain is the most important chemical parameter of complex grain quality. The research was conducted in order to determine the influence of the variety and different doses of nitrogen on the grain yield and protein content in triticale grain. The experiment, set up according to a random block system in four replications on eutric cambisol soil in the north of Montenegro, included five varieties of winter triticale (Odyssey, Kg-20, Triumph, Rtanj and Tango). In addition to the control (variant without fertilization), four more fertilization variants were applied. The results of the research showed that the application of fertilizers has a significant influence on the values of the observed traits on the one hand, but also that the grain yield and protein content in the grain is largely conditioned by the genotype. In this regard, the highest average protein content in the grain had the variety Triumph in both tested years. The protein content of all tested varieties was significantly lower in the control variant compared to the fertilized variants. The highest grain yield in the first year had the variety Tango while the highest yielding variety in the second year was variety Rtanj.
