Cultivation of sesame
In this presentation we are going to discuss about cultivation of
sesame and its oil extraction.
sesame have tendency to absorb high amount of nutrients from soil
and to grow well even at drought conditions.
We started the cultivation at the starting of winter season since the
crop can grow using the moisture caused by morning dew drops.
This cultivation took place in our lands situated in the Village
We chose one acre for black gram cultivation.
We also cultivated black gram in our ancestral residential plots in
We didn’t irrigate the lands but used the monsoon rain and
moisture from condensed fog for cultivation.
We distributed the sesame seeds and ploughed the soil a day after rain
We allowed the sesame plant to grow naturally like weeds
without any human interference
The pods got harvested manually by 95 days and collect in bunches
The harvested plant bunches were collected as a heap
A close-up view of stacked plants which are later covered with
tarpaulin sheet for three days for the grains to mature completely .
In this process even partially matured white seeds will also get
matured by turning black
After stacking the plants were dispersed to get completely dry. The
dried plant were beaten by stick in order to get the sesame seeds
Simultaneously at Neyyadu pakkam village we sowed
sesame for 20 cents at our residential plots to avoid the weed
Lets have a look how we cultivated sesame at this place in
the following slides.
We ploughed the land after dispersing the sesame seeds
We can notice matured black sesame by ninety five days
We harvested small amount but good quality of sesame seeds from
this place. We kept this sesame as seeds to sown in next season
Around 130 kg of sesame were soaked in water to dissolve added clay
We washed the sesame trice completely and filtered it.
We dried the cleaned sesame on terrace under sunlight
The sesame got completely dried for three days
We used 2 kg of Chemical free jaggery for every 10 kg of sesame to
expel oil from it.
We also used purified and RO,UV treated water to sprinkle over
sesame as lubricant in oil extraction process.
The oil got extracted in a cleaned wooden expeller by cold
pressing(temperature developed in this process was less than 40◦C).
We got light colored ( due to washing) aromatic sesame oil which was
allowed to stay Undisturbed for three days in order to settle down the
dispersed particles as oil cake. The clear oil was transfer in a cleaned
nylon can and stored in dark dry cold place
We burnt the sesame straw inside a oil drum to get clean ash
The ash can be dissolved in water and filtered to use as nutritious
insect repellant spray for next crop.
We got good quality and quantity of sesame from small area.
We found that the land soil in which sesame was cultivated
retained moisture and their was a good sign of earth worm
activities comparatively to the Adjacent bare lands.
When we washed sesame to remove clay and dust we observed
black color substance from sesame external cover getting
dissolved in the water and made the water black .We stored the
water separately and testing its properties.
We found the ash of the sesame straw was highly alkaline
which has t be diluted well before applying to other crops.
Next time we are planning to transplant sesame saplings at
equal distance and compare its yield
