Triticale is the first man-made cereal grain crop species resulting from the hybridization of wheat (Triticum aestivum) with rye (Secale cereale), the name of which combines the scientific names of the two genera involved (Triticosecale or Triticale) . As a hybrid species, it combines rusticity from rye with productivity from wheat as well as other many attributes of both of its parents.Being a plant exclusively done by humans Triticale sp. inherited from parents specific agricultural skills but most important these herb valuable features incorporated into its genome in terms of resilience to adverse conditions. The most important components in triticale production are the number of grains / spike and grain weight / spike, the last being determined as a result of grain filling rate and the duration it was made.The aim of this study was to test the performance of the genotypes studied by analyzing the main elements of productivity and their behaviour under the influence of environmental factors and depending on agro-technical treatment used. The experiments were conducted over two years, 2010-2011 and 2011- 2012, at Agricultural Research and Development Station from Turda. The biological material used, consist of 25 winter triticale genotypes from different sources. Yield and yield component values were different from year to year due to climatic conditions of each growing season.The trial was set in three replication arranged by quadratic balanced latice method with repeated basic scheme which allow us to use two levels of fertilization, respectively lower fertilization applied at plant emergence and additional fertilization at stem elongation stage. At maturity, before harvest plant height was measured. Also in order to determine the influence of additional fertilization level the yield components have been determined. So, were collected from each experimental plots 25 ears which were determined based on the main elements of productivity (number of grains per spike, grain weight per ear (g), one thousand grains weight (TKW), specific weight (Kg/hl), etc.)Based on the results obtained were established some relationships between the main components of production and their influence on other factors apply.
