Gaillardia planted at population density gradients was supplied with three levels of nitrogen (150, 220 and 250 kg N/ha) and three levels of phosphorus (60, 120 and 160 kg P/ha) to study the growth and yield of Gaillardia. The flower yield of gaillardia differed significantly for the spacing levels but not for N and P levels. The maximum flower yield of 35.5 t/ha was obtained when spaced at 30 x 20 cm. All the first order interactions were significant at P 0.05. The highest flower yield of 42.2 t/ha was realised when gaillardia was spaced at 30 x 20 cm with an application of 150 kg N and 80 kg P per hectare with a common dose of 60 kg K. The uptake of nutrients by gaillardia did not commensurate with increase in levels of application although there were significant differences between the treatments
