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

Keywords: Triticale, Fertilization, Variety, Grain yield, Protein content INTRODUCTION Triticale, a hybrid created by crossing wheat and rye, combined the positive characteristics of the parent species. [...]he inherited the ability to survive strong frosts from rye, and high genetic potential for yield and increased tolerance to diseases from wheat. The nitrogen content in the grain, among other things, depends on the mutual relationship of nutrients in the applied fertilizers. [...]the use of nitrogen with potassium and NPK - fertilizers with a nutrient ratio of 1:1 increases the protein content in the grain, while the increased share of other nutrients in relation to nitrogen reduces the protein content (Tyrone, 2002; Jelić et al., 2004; Lalevic et al., 2019). The analysis of meteorological conditions during the two ~ year research showed that the temperature conditions, but also the amount of precipitation had a certain influence on the values of the observed traits in the selected genotypes of triticale included in the research. [...]to the amount of precipitation, the average air temperatures for the observed period in both years of the research were higher in relation to the multi-year average. [...]the average air temperature for the period October-July in the first year of the research was 1.7 ° C, and in the second 1.2 ° C higher than the multi-year average (Table 1).
