Abstract
A field experiment was conducted at the experimental farm, Department of Agronomy, SASRD, Nagaland University to study sesamum on nutrient uptake, economics and nutrient concentration on post-harvest soil as affected by different levels and sources sulphur. The experiment was laid out in randomized block design (RBD) with three replications. There were ten treatments viz., T1 (control), T2 (10 kg gypsum ha-1), T3 (20 kg gypsum ha-1), T4 (30 kg gypsum ha-1), T5 (40 kg gypsum ha-1), T6 (control), T7 (10 kg elemental sulphur ha-1), T8 (20 kg elemental sulphur ha-1), T9 (30 kg elemental sulphur ha-1) and T10 (40 kg elemental sulphur ha-1). The total Nitrogen (70.72 kg ha-1), Phosphorus (7.91 kg ha-1), Potassium (28.52 kg ha-1) and Sulphur (6.05 kg ha-1) uptake by the plant was recorded highest with 40 kg elemental sulphur ha-1. Treatment T10 recorded the highest net return as well as B:C ratio (%) with Rs. 24,130.40 ha-1 and 1.21 respectively, while T1 and T6 recorded the lowest net return and were statistically at par. The available soil Nitrogen (435.53 kg ha-1) after harvest was recorded highest in T1 (control). The available soil Phosphorus (48.75 kg ha-1) and Potassium (214.27 kg ha-1) was recorded highest in T1 (control) and available soil Sulphur (22.15 kg ha-1) was recorded highest in T10.
