Comparative Study on Fiber Dimension, Density and Chemical Components of Two Varieties of Rapeseed Straw

Oil seed rape (Brossica napus} planting is increasing as the Iranian Ministry of Agrieulture Jehad policy to provide supply of oil food in Iran. The objeetive of this study is utilization of rapeseed straw as a considerable raw material for paper industry whereas there is shortage of lignocellulosic material in Iran. Sampling was earried out from two varieties of oil seed rape, Hiola 401 and PF, based on initial eompatibility experiments and yield in Mazandaran province from Baye-colla researeh station. The results show that at least 4 ton/hect. oven dry rapeseed straws are available. There were significant differences between fiber width, lumen diameter, ash and extractive contents in two varieties. Rapeseed straw as a lignocellulosic material was achieved at 10 score according to the five characteristics consisting ofphytology, fiber dimension, fiber yield, chemical components and appearance feature. This means more studies are necessary to make a final assessment.
