Abstract: A field experiment was conducted on growth and yield parameters of Palmarosa at Medicinal and Aromatic plants Research station, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad, during kharif 2016-17 and 2017-18. An experiment with Randomised Block Design was conducted with the objective to “Study the influence of Nitrogen and Sulphur on herbage and essential oil yield of palmarosa by following the technical programme as T1(100-60-40 Kg NPK/ha), T2(150-60-40 NPK/ha), T3(200-60-40 NPK/ha), T4(100-60-40 NPK/ha+30 kg Sulphur), T5(150-60-40 NPK/ha+30 kg Sulphur), T6(200-60-40 NPK/ha+30 kg Sulphur), T7(100-60-40 NPK/ha+60 kg Sulphur), T8(150-60-40 NPK/ha+60 kg Sulphur), T9(200-60-40 NPK/ha+60 kg Sulphur. The fresh herbage yield per hectare was highest (12.25 t) with 200:60:40 kg NPK/ha+60kg Sulphur/ha followed by 200:60:40 kgNPK/ha+30kg Sulphur/ha while the lowest yield per hectare (8.50t) was noticed with 100:60:40 kgNPK+60 kg Sulphur/ha. Considering the importance of crop, every effort is being made to increase the oil production of the crop by using improved nutrient management practices.
