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.
