Abstract

The biometry, morphological properties and chemical composition of bagasse, corn, sunflower, rice, and rapeseed residues were analyzed. The results revealed there were significant differences among the agricultural residues in biometry and morphology properties and chemical composition. The greatest proportion of fiber length (1.32 mm) and cellulose (55.56%) was found in residues of bagasse, with a low ash (1.78%) and lignin (20.5%). The rice and rapeseed residues had highest amount of ash and extractive component. The slenderness and flexibility ratios of the all types of agricultural residues fibers were very to similar to some of hardwood and softwood species. In addition, the lignin content of the studied agricultural residues is less than hardwood and softwood species.

 

Key words: Agricultural residues, biometry properties, chemical composition, morphological properties.
