Description |
A field experiment was conducted during kharif season of 2012 on farmer?s field at Marewad village of Dharwad district to study the sources (gypsum, single super phosphate and elemental sulphur) and levels of sulphur (10, 20, 30 and 40 kg ha-1) on growth and yield of sesame (Sesamum indicum L.). The experiment was conducted in RCBD with factorial concept with three replications. Among the sources of sulphur, application of gypsum (637 kg ha-1) and single super phosphate (655 kg ha-1) recorded significantly higher seed yield compared to elemental sulphur (594 kg ha-1). Application of sulphur through single super phosphate and gypsum resulted in higher yield attributes (number of capsules plant-1, number of seeds capsules-1 and seed weight plant-1) leading to higher seed yield. Among levels of sulphur, an application of 30 and 40 kg ha-1 resulted in significantly a higher seed yield (668 and 680 kg ha-1 respectively). Control treatment recorded significantly a lower seed yield (540 kg ha-1). Growth parameters (plant height, number of primary branches plant-1, leaf area index at harvest and dry matter production plant-1) recorded significantly higher at 30 and 40 kg S ha- 1compared to lower levels of sulphur. Single super phosphate and gypsum application also resulted in significantly higher oil content (48.68 and 48.68 % respectively) and protein content (25.63 and 25.54 % respectively), whereas among the levels of sulphur 30 and 40 kg S ha-1 recorded significantly higher oil content (48.80 and 49.08 % respectively) and protein content (25.94 and 26.13 % respectively) compared to lower levels of sulphur. Significantly higher N, P, K and S uptake was observed at 30 and 40 kg S ha-1 compared to lower levels. Sulphur application at 30 and 40 kg ha-1 recorded significantly higher net returns (`17717 and 17752 ha-1 respectively) and B: C ratio (2.15 and 2.11 respectively) than lower levels. |
