The Influence of the Sowing Rate and Foliar Fertilization on the Yield of Some Tritical Varieties in the Context of Climate Change in Northwest Romania

Triticale is recognized worldwide due to its high protein and lysine content, high production capacity and adaptability to biotic and abiotic stress conditions, these qualities being taken over from wheat and rye. Triticale is widely used in various fields such as animal feed in various forms, in medicine, the bakery, beer, alcohol, cellulose, bioethanol industry and many others. Thus, the demand for triticale grains is increasing, and this has led to the research and improvement of culture technology to obtain superior products, both quantitatively and qualitatively. The purpose of this study was to identify the best varieties of triticale cultivated in the north-west of Romania, sown in different plots and fertilized on the ground or additionally, the study being carried out over a period of two years at the Livada Agricultural Research and Development Station, Satu Mare county. The study was located on an acidic soil with a pH between 5.19 and 6.65 and a humus content of 2.82%. The climatic conditions in the reference period were extremely variable, in the first year a deficit of more than 90 mm/m2 of precipitation was registered, and in the second year of the study, an increase of more than 34 mm/m2. The effects of additional fertilization were influenced by the level of precipitation, so in the experimental variants additionally fertilized, lower productions were obtained compared to the variants fertilized only on the soil. Compared to the Negoiu control, the Utrifun variety proved to be the most productive, but this will be proven in the following years of study, under different climatic conditions.
