Three field experiments were conducted at Guneid, Sudan, in which N was applied to sugarcane (A) in one dose, (B) in split doses at 2 and 4 months, and (C) as a single dose 4 months from planting. Nitrogen application generally increased the yields of both cane and sugar but did not significantly affect sucrose recovery. Correlation coefficients for yields of cane and sugar suggested that the application of 88–176 kg N/ha 2 months after planting was economic.
