A greenhouse experiment was conducted at the Department of Agronomy, University of Ibadan, Nigeria to evaluate the optimum level of sulphur for the growth and yield of Celosia argentea during August to October 1991. Five sulphur levels (0,2,5,5,0, 7.5 and 10.0Ug/g) were tested on Celosia in a completely randomized design. Application of sulphur significantly increased leaf number, plant height, leaf weight, and stem weight. The optimum sulphur rates for leaf, stem and shoot production appears to be 7.5Ug/g. The results show that sulphur nutrition is necessary for the optimum growth and yield of celosia.
