The effect of sulphur in the form of ammonium sulphate on the performance of sugarcane under heavy clay soils of Sudan was conducted at the research farm of Kenana Sugar Company during two consecutive seasons (2012/13- 2013/14). The experiment was laid out in a randomized complete block design (RCBD) with four replications and gross plots of 4 rows x 10m length x 1.50m width with a 5m length inspection road between each block to evaluate the effect of sulphur on sugarcane yield and quality. Applications of fertilizers were at the rate of 69 and 23kg/feddan for Nitrogen and phosphorus respectively (nitrogen in the form of urea & ammonium sulphate and phosphorus in the form of tri-super phosphate (TSP) (standard practice) and Sulphur at the rate of 0.00, 12.00, 24.00, 36.00 and 48.00 kg Sulphur/feddan in the form of ammonium sulphate. The results revealed that Sulphur (S) had a positive impact on sugar and cane yield/feddan Compared to (control) and the negative impact on plant density, also insignificant on sugar yield/feddan and its application had a significant effect on the Fiber% cane, but there were insignificant differences among means of Pol% cane, Brix% cane, ERSc (estimated recovery of sucrose), purity% and moisture %cane, also Insignificant differences were obtained among the means of the internodes number and plant height of all tested treatments.
