Abstract: A field experimented was conducted at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh during spring season of 2018-19 and 2019-20 to study the effect of different herbicide combinations with allelopathic plant extracts on growth and quality of sugarcane. Different treatments failed to show any significant effect on germination and qualitative characters of sugarcane. However, The results reveal that the maximum plant height was observed with weed free (3 hand weeding at 30, 60 and 90 DAP) during both the years. In case of chemicals, significantly higher plant height at harvest was found with pre-emergence application of halosulfuron methyl + metribuzin which was statistically at par with application of halosulfuron methyl + metribuzin (75% R.D) + 25% SWE and halosulfuron methyl + metribuzin (75% R.D) + 25% SUWE during both the year of the study.
