A field experiment was conducted to study the different levels of Nitrogen and Phosphorus on nutrient content and uptake of Palmarosa under rainfed conditions on vertisols at Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2007–2008. The experiment was laid in factorial randomized block design with three replications. There were four levels of nitrogen viz., 0 kg (N₀), 40 kg (N₁), 60 kg (N₂), 80 kg (N₃) and three levels of phosphorus 0 kg (P₀), 20 kg (P₁), 40 kg (P₂) ha⁻¹. The results revealed that the nitrogen content (0.85%), phosphorus content(0.69%) and potassium content (0.56%) in the crop was highest when treated with 80 kg (N₃) ha⁻¹ and the nitrogen content (0.74%), phosphorus content (0.60%) and potassium content (0.48%) was also more with the application of 40 kg (P₂) ha⁻¹. Similarly the crop uptake was recorded highest with application of 80 kg N ha⁻¹ where the nitrogen uptake was (30.50 kg ha⁻¹ phosphorus uptake (14.36 kg ha⁻¹) and potassium uptake (13.25 kg ha⁻¹ while the nitrogen uptake (22.12 kg ha⁻¹ phosphorus uptake (11.90 kg ha⁻¹) and potassium uptake (10.12 kg ha⁻¹) was also more when treated with 40 kg (P₂) ha⁻
