Triticale is a cereal species obtained by crossing the wheat with rye, and therefore it has specific traits between those of the parental species. There are two important factors in establishing the resistance to plant lodging: the plant height and thickness of straw. These two traits with importance upon the plant lodging are determined by the plant genetics and are influenced, between some limits, by the environmental and technological factors. In this respect, the aim of the paper is to present the results obtained at different triticale varieties under different technological and climatic conditions regarding the biometrical traits plant height and straw thickness. The experimental data were obtained in field experiments located in South Romania. In the agricultural year 2012-2013, ten triticale varieties were studied. In the agricultural year 2013-2014, two triticale varieties were studied under three technological conditions: two preceding crops (sunflower and maize); two soil tillage (ploughing and harrowing); six nitrogen application variants (respectively 0+0+0, 40+40+40, 40+80+0, 0+40+80, 0+80+40, and 0+120+0 kg.ha-1). For each triticale variant and replication and in each experimental year, there were measured the plant height and stem diameter at soil level. The obtained results showed that the plant height and straw thickness do not correlate each other according to the triticale variety. But, for a given triticale variety, the plant height correlates negatively with the straw thickness, according to the plant water supply, preceding crop and soil tillage. However, nitrogen application determined the increasing of both studied plant traits, respectively the plant height and the straw thickness, the effect being different according to the split nitrogen applications.
