Residue management in sugar-cane cultivation is crucial for improving soil health, as it positively impacts the increase of sugar cane productivity. The study aimed to describe the effect of sugar-cane residue management using ammonium sulfate fertiliser and its substitute on cane and sugar yield in plant and ratoon cane. A pot experiment was conducted using a factorial block randomised design. The first factor is N and S fertilisation, consisting of ammonium sulfate (AS), urea, gypsum and bio-compost. The second factor is the residue management consisting of four levels, namely burnt residue, residue incorporated into the soil, residue put on the soil surface and composted residue. These treatments were tested on the first and second cane. The results showed that the composted residue gave the highest increase in cane and sugar yield by 83.7% and 81.2%, respectively on the ratoon cane when compared with the plant cane. Fertilisation using urea, bio-compost and gypsum showed the highest cane yield. The results suggested that composted residue can be applied in sugar-cane cultivation in dry land to increase nutrient uptake and cane and sugar yield in plant and ratoon cane.
