During the period 2013/2016, at the experimental field of Crop science department at Agricultural University - Plovdiv a field experiment was conducted, using a block method in 4 repetitions and size of the experimental plot 20 m2 . Two triticale varieties - Musala and Attila were tested. The two varieties were grown at fertilization levels, N0, N120, N160, N200, N240 kg/ha. The green mass yield value was reported in heading and milk maturity phases. Plant height and the yield structural elements have been determined. This research aimed to determine the influence of triticale structural elements on green mass yield, as a source of renewable energy, depending on nitrogen fertilizers and the phase of harvesting. The obtained results show that the structural elements have highest influence on the green mass yield. In milk maturity phase, the structural elements values increase, compared to heading phase. Increasing nitrogen fertilizers, leads to increasing in yield values, and highest yield was reported at N200 variant. Attila variety is characterized by higher stems and longer spikes than Musala variety. The differences in leaves number and stem thickness between the two varieties are negligible.
