Abstract: Stalks of non-wood herbaceous species Amaranthus hybridus was investigated by soda pulping to investigate the future of Amaranthus hybridus species stalks as a auspicious renewable cradle in pulp and paper industry, which is profusely accessible in Kashmir (India) along road sides, foot paths, wastelands, pastures, hilly areas as unwanted weed. In the opportunity of current study, the element characterization of Amaranthus hybridus stalk dust, chemical characterization of liquor analysis and paper properties were carried out. The elemental analysis of test species bared that Ash%, Lignin%, Hot water solubility%, 10% NaOH solubility, Alcohol-benzene solubility% and Holocellulose % content were detected in the array of 11.03, 17.55, 20.25, 40.40, 6.64 and 62.41 respectively. Liquors obtained after digestion of test species results what is called as black liquor and the chemical analysis of the liquor includes pH, total solids, chemical oxygen demand and color which were chronicled 8.84, 6.82%, 226240 ppm and 115505 PCU respectively and for wash liquor the corresponding values were recorded 8.45, 1.90%, 113100 ppm and 31684 PCU. The cooked Amaranthus hybridus stalks subjected to soda pulping process and were no chemical was added (control) results in pulp and the strength properties of standard resultant sheets of 60 gsm of beaten pulp at 300 ml csf were assessed in terms of tensile strength (Nm/g), tear index (mN.m²/g), burst index (Kpa m²/g), double fold number. The overall results revealed that pulp obtained from Amaranthus hybridus stalks at 8% soda pulping has a auspicious potential to be used in pulp and paper industry.
