An investigation was carried out to ascertain the effect of planting density and nitrogen on the performance of kaon. The planting density was regulated by the seed rate per hectare. Four different seed rates (4, 6, 8 and 10 kg ha1) and five nitrogen levels (0, 15, 30 and 60 ka ha1) were used for this study. The result of the study revealed that the planting density significantly influenced the yield and yield contributing characters such as plant population per square meter, plant height, number of tiller per plant, effective tiller per plant, grains per panicles, grain and straw yields. Nitrogen too significantly influenced the yield and yield contributing characters except plant population per square meter. The maximum grain yield (1.98 t ha1). The dose of 60 kg N ha-1 produced the highest grain yield (1.87 t ha1) and it was statistically similar to 45 kg N ha1 (1.82 ha1). The interaction effect due to seed rates and nitrogen levels showed significant influence on effective tiller per plant, grain and straw yield and harvest index. The combination of 10 kg seed and 60 kg nitrogen per hectare produced the highest grain yield (2.15 t ha1).
