  1. 1. Traditional Technology Solutions Presents Organic Farming Methods – Part 6 Cultivation of sesame and its oil extraction Presented by, N. S. Santhana Krishnan, Traditional Technology Solutions, E-mail:, Website: .
  2. 2. 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 named “Thiru-Magaral”.  We chose one acre for black gram cultivation.  We also cultivated black gram in our ancestral residential plots in Neyyadupakkam village.  We didn’t irrigate the lands but used the monsoon rain and moisture from condensed fog for cultivation.
  3. 3. We distributed the sesame seeds and ploughed the soil a day after rain
  4. 4. We allowed the sesame plant to grow naturally like weeds without any human interference
  5. 5. Seeds got germinated as plants by seven days
  6. 6. Sesame plants gown around four inches high after fifteen days of seeding
  7. 7. Plants growth in twenty days
  8. 8. Plants after thirty five days
  9. 9. Plants after forty five days
  10. 10. Plants started developing sesame pods after sixty five days
  11. 11. The sesame pods got matured by ninety days
  12. 12. The pods got harvested manually by 95 days and collect in bunches
  13. 13. The harvested plant bunches were collected as a heap
  14. 14. 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
  15. 15. After stacking the plants were dispersed to get completely dry. The dried plant were beaten by stick in order to get the sesame seeds
  16. 16. Kindly note: Simultaneously at Neyyadu pakkam village we sowed sesame for 20 cents at our residential plots to avoid the weed occupation. Lets have a look how we cultivated sesame at this place in the following slides.
  17. 17. We ploughed the land after dispersing the sesame seeds
  18. 18. Sesame plants got germinated
  19. 19. Plants growth after 30 days
  20. 20. Plants growth after forty five days
  21. 21. Plants growth after sixty days
  22. 22. Pods started to appear by seventy five days
  23. 23. We can notice matured black sesame by ninety five days
  24. 24. We harvested small amount but good quality of sesame seeds from this place. We kept this sesame as seeds to sown in next season
  25. 25. Around 130 kg of sesame were soaked in water to dissolve added clay particles.
  26. 26. We washed the sesame trice completely and filtered it.
  27. 27. We dried the cleaned sesame on terrace under sunlight
  28. 28. The sesame got completely dried for three days
  29. 29. 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.
  30. 30. The oil got extracted in a cleaned wooden expeller by cold pressing(temperature developed in this process was less than 40◦C).
  31. 31. 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
  32. 32. We burnt the sesame straw inside a oil drum to get clean ash
  33. 33. The ash can be dissolved in water and filtered to use as nutritious insect repellant spray for next crop.
  34. 34. Conclusion:  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
