Abstract: A research investigation was conducted during kharif season 2015 to study the effect of phosphorus and sulphur nutrition on growth, yield and quality attributes of sesamum (Sesamum indicum L.) under acidic soil of Nagaland at the Department of Agricultural Chemistry and Soil Science, School of Agricultural Sciences and Rural Development (SASRD), Nagaland University, Medziphema campus, Nagaland. The experiment was carried out in a Factorial Completely Randomized Design comprising of 9 treatments P (0, 25 and 50 kg ha^-1) and S (0, 20 and 40 kg ha^-1) and each treatment was replicated three times. The study revealed that the growth parameters such as plant height, stem diameter and number of branches showed significant response to phosphorus and sulphur application at increasing rates after 30, 60, 90 days of sowing and at harvest except number of branches at 30 DAS was not significant but thereafter significantly affected by the treatment combinations. Highest growth attributes were found with P₅₀S₄₀. Significantly best yield and yield attributing parameters were obtained with P₅₀S₄₀. The oil content in seeds was significantly affected and highest was found with P₅₀S₄₀. The protein content increased with increased phosphorus levels.
