Abstract
Two sources of sulphur-coated urea (SCU) were compared with single or split applications of calcium ammonium nitrate (CAN) as sources of N for cotton and sorghum in the savannah zone of Nigeria. On only one of the three sites, at the lowest rate of N application (40 kg/ha), SCU-11, with a dissolution rate of 11% in 7 days, was more effective for grain yield of sorghum than SCU-30, having a dissolution rate of 30% in 7 days, or CAN. On the same site, a single application of SCU-11, SCU-30 or CAN produced a higher sorghum yield than a divided application of CAN at the same rate. There were no significant differences between treatments at the other sites or in experiments with cotton
