Abstract

Oil seed rape (Brassica napus) planting is increasing as the Iranian Ministry of Agriculture Jehad policy to provide supply of oil food in Iran. The objective 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 carried out from two varieties of oil seed rape, Hiola 401 and PF, based on initial compatibility experiments and yield in Mazandaran province from Baye-colla research 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 of phytology, fiber dimension, fiber yield, chemical components and appearance feature. This means more studies are necessary to make a final assessment.
