EFFECTS OF AGROCLIMATIC CONDITIONS AT TRIAL LOCATIONS AND FERTILIZATION ON GRAIN YIELD OF TRITICALE

Triticale is a plant species which is characterized by high genetic potential for grain yield, as well as good nutritive properties of its grain, while it is not so demanding as wheat in regard to agrotechnic measures and ecological conditions, so it is regarded as a very promising crop. In order to reach high and stable grain yield, few demands ought to be fulfilled, such as favorable agroclimatic conditions of the production area, growing superior cultivars, and good production technology, especially sufficient and well-balanced mineral nutrition. In Serbia, acid soils represent a serious problem for field crop production. These are soils with bad air-water and physico-mechanical properties, so plant production carried out on them is highly unstable. For that reason, correction of those soils acidity is necessary to improve their productive properties, which has a long-term effect on increasing yield of the grown crops. This paper deals with the effect of agroclimatic conditions at trial locations and fertilization on grain yield of triticale. The experiment was established at two locations (Zajecar and Kraljevo), during two years (2009 and 2010), and included control variant without fertilization and three variants fertilized by mineral
