Description A field experiment entitled “Response of sesame (Sesamum indicum) to
sources and levels of sulphur during summer” was conducted at the Student’s
Farm, College of Agriculture, Rajendranagar, Hyderabad, during summer,
2007. The experiment was laid out in a randomized block design with factorial
concept and was replicated thrice. The treatments comprised of three sulphur
levels viz., 10, 20 and 30 kg ha-1 and three sources of sulphur viz., single super
phosphate, gypsum and elemental sulphur along with one control (no
application of sulphur). The cultivar tried was Swetha, a white seeded
sesamum variety recommended for Telangana region of Andhra Pradesh.
Sulphur sources as well as levels have significantly influenced the plant
growth characters, yield attributes, yield (seed & oil), economic returns and
nutrient uptake (NPK & S). Significant interaction effects were not observed
for many characters except on oil yield.
Application of sulphur @ 30 kg ha-1 to summer sesamum resulted in
significantly increased plant height, dry matter production and number of
branches plant-1. Regarding the sulphur sources, SSP proved its superiority to
other sources for the above said growth characters.
The yield attributes viz., number of capsules plant-1 and test weight of
seeds were found to be maximum with sulphur application @ 30 kg ha-1.
Among the sources of sulphur, SSP recorded significantly highest number of
capsules plant-1 and test weight compared to other sources.
The highest seed and stover yields, harvest index were obtained with
sulphur application @ 30 kg ha-1, followed by 20 kg S ha-1. Among the
sources of sulphur, SSP application resulted in significantly higher seed and
stover yields. Lowest seed yield was recorded with control (no application)
followed by elemental sulphur.
Maximum oil content and yield were recorded by 30 kg S ha-1. Among
the sources, SSP recorded highest oil content and oil yield. Application of
sulphur in the form of gypsum was the next best. The lowest oil yield was
recorded by elemental sulphur and least in control.
The interaction between levels and sources of sulphur was significant
with respect to oil yield only. Single super Phosphate at 30 S kg ha-1 recorded
maximum of oil yield followed by SSP at 20 S kg ha-1.
The highest gross returns and net returns were realized due to sulphur
application @ 30 kg ha-1, whereas benefit-cost ratio was maximum with
gypsum source of S application.
