Abstract: The study was conducted to estimate the chemical and physico-mechanical characteristics (quality of fibre) of jute fibre, the popular variety of O-9897 was grown with the application of water hyacinth, chemical fertilizer in soil and control under proper agricultural management. The water hyacinth responded comparatively better in enhancing the fibre quality than chemical fertilizer. Lower chemical constitutes the non-cellulosic portion (lignin and hemicellulose) in fibre indicates good quality, which found with water hyacinth. The percentage of lignin and hemicellulose in fibre with water hyacinth 12 and 20% with chemical fertilizer 13 and 21% and with control 13.6 and 21.20% respectively. The enriched physico-mechanical properties obtained with water hyacinth over the chemical fertilizer and control. The lower values of fineness (35φ) and higher values of whiteness (22.3%), bundle strength (7.61 lbs/mg), tensile strength (80.30 lbs/mg) and breaking tenacity (39.50 lbs/mg) ascertain the high quality of fibre found with water hyacinth. And the values found in fibre with chemical fertilizer, fineness-36.50φ, whiteness 21%, bundle strength-6.99 lbs/mg, tensile strength-78.98 lbs/mg and breaking tenacity- 39 lbs/mg. Thereby the study showed that chemical and physico-mechanical properties of fibre increased with water hyacinth. Study also indicates that the sole chemical fertilizer application in soil may not be possible to maintain the quality of fibre, it may be need an integration of organic matter and chemical fertilizer application in soil to enrich the fibre quality.
