DIFFERENCES IN GRAIN YIELD AND GRAIN QUALITY TRAITS OF WINTER TRITICALE DEPENDING ON THE VARIETY, FERTILIZER AND WEATHER CONDITIONS

Abstract

The research conducted in the north of Montenegro in the period from 2017-2019 aimed to examine the impact of different fertilizer variants on the yield and grain quality traits in four varieties of winter triticale. The research included the control and three variants of nitrogen fertilization: 60 kg ha-1 (N1), 100 kg ha-1 (N2) and 120 kg ha-1 (N3). In all fertilizer variants, in addition to nitrogen, another 100 kg of ha-1 phosphorus and potassium were used. The results of the research showed that all examined varieties reacted positively to the application of mineral nutrition both by changing the productive characteristics and by changing the grain quality. The greatest positive effect on all examined parameters that affect productivity had the variant of fertilization in which nitrogen was used in the amount of 120 kg ha-1. The variety PKB Vožd had the highest yield (5.79 t ha-1) in both years of research, while the cultivar Favorit had the lowest yield (4.67 t ha-1). The variance analysis clearly indicated that the individual effects of variety and fertilization, as well as the effects of the interaction between variety x fertilization and fertilization x year on grain yield in the examined winter triticale varieties were significant (p<0.01).
