Abstract: Abstract Sugarcane is an industrial crop globally used for producing biofuels and bioproducts and is the only source of white sugar in Bangladesh. However, labour-dependent cultivation and climate change are responsible for the higher production costs and lower yield of sugarcane, and these factors are barriers to sustainable sugarcane farming in Bangladesh. In this paper, the prospects of existing sugarcane farming practices are described, and some improved cultivation and management practices addressing the principles of conservation agriculture (CA) in overcoming these barriers are evaluated. Excessive tillage, burning of trash after harvesting, and mono-cropping have been identified as crucial factors that increase sugarcane production cost, deteriorating soil health, and decreasing cane yields. Several improved conservation tillage machines used for cereals, pulse, and other crops are becoming more accessible to farmers in Bangladesh, but these machines are not used for sugarcane crops. Minimum tillage can also be a resource-saving tillage option for cultivating sugarcane but is limited in sugarcane production owing to the absence of suitable machinery. However, the irrational removal and burning of the residue in the sugarcane farming systems may have adverse effects on the environment. Intercropping not only increases economic benefits but also minimises the negative impact of mono-cropping. We suggest that minimum tillage, residue mulching, and intercropping should be applied as profitable and sustainable cultivation practices in sugarcane farming. Therefore, both research and extension activities addressing the use of appropriate CA technologies, including conservation tillage machinery improvements, could help to achieve sustainable sugarcane farming in Bangladesh.
