EFFECT OF CULTIVAR AND INCREASED NITROGEN QUANTITIES ON SOME PRODUCTIVE TRAITS OF TRITICALE

According to the results of Stošović (2009), triticale achieved high yields in the hilly-mountainous region and in the application of lower cultivation technology, while under optimal conditions, in terms of grain yield, it has mostly reached the leading varieties of wheat, and outreached the varieties of rye, barley and oats (Biberdžić et al. 2012). Cultivars of triticale are distinguished by high genetic potential for yield, and that is why triticale can be considered a perspective plant species, especially from the point of view of climate change, which through increasing temperatures and drought show an even more intense influence on cultivated plants. In the tested soil samples, which were pre-dried to air-dry state and crushed in a porcelain mortar to a particle size of 2 mm, the following chemical and physical properties were determined: land reaction (pHKCl) by the combined glass electrode, the content of humus by the Kotzman method, content of CaCO3 volumetric, using Scheibler calcimeter (Džamić et al., 1996) and the content of the easy-access P and K by the Al-method, by Egner-Riehm (1960). In February 2012, a lot of low temperatures were observed, especially in the first decade, when the temperature was -9.6°C. The snow cover in this year has significantly contributed to the protection of plants from freezing, but its long retention slowed down the vegetation in the spring.
