Effects of different levels of nitrogen, phosphorus and sulphur on yield and yield attributes of summer sesame (Sesamum indicum L.)

Eighteen treatment combinations consisting of three levels of nitrogen (25, 50 and 75 kg ha-1), three levels of phosphorus (12.5, 25 and 37.5 kg ha-1) and two levels of sulphur (0 and 20 kg ha-1) were tested in factorial randomized block design with three replications. A significant increase in growth and yield attributes viz; plant height, number of branches/plant, length of capsule, number of seeds/capsule and test weight was obtained with increase in nitrogen levels from 25 to 50 kg N/ha., phosphorus levels from 12.5 to 37.5 kg/ha, Sulphur levels from 0 to 20 kg ha-1
