These slides discuss our recent cultivation of groundnut and its oil extraction. We have organically cultivated groundnut and its yield was better than an average non-organic farming. The procedures are presented in the slides.

  2. 2. Groundnut cultivation  In this presentation we are going to discuss about cultivation of groundnut and its oil extraction.  We have cultivated groundnut in a land which was not in use for more than 12 years(chemical traces was almost nil).  We started the cultivation at the starting of winter season simultaneously with black gram and sesame.  This cultivation took place in our lands situated in the Village named “Neyyadupakkam”.  We chose 50 cents for groundnut cultivation.  We did irrigation for plant twice and third irrigation for plucking(harvesting) groundnut.  We added quarter ton of composted cow dung and 5 packets of Rhizobium bacteria (to improve groundnut formation at root nodes)provided by state government for groundnut cultivation.
  3. 3. Initially we made the land wet and puddle the soil trice to make it powder and soft
  4. 4. Two Ox driven ploughs were used to make ridges and furrows in the puddled land
  5. 5. When the seeds were sown in furrows the adjacent ridge was made to furrow i.e. The ridge soil got shifted to seeded furrow and buries the seeds under soil.
  6. 6. We did first irrigation after twenty days of seeding
  7. 7. Plants grown after forty days
  8. 8. Plants grown after sixty days
  9. 9. Plants started maturing after 80 days
  10. 10. Partially matured groundnut by eighty days
  11. 11. Fully matured groundnut by 100 days
  12. 12. Unshelled groundnut after post harvest drying (clay sticking on shells).
  13. 13. After cleaning the de-Sheller machine we de-shelled the groundnuts
  14. 14. De-shelled groundnuts were manually cleaned for small nut which are not de-shelled and also for clay balls.
  15. 15. Groundnuts were cold pressed (Temperature < 40◦C) using wooden expeller.
  16. 16. We used purified and RO, UV treated water to facilitate oil extraction to minimize bacterial infestation and increase its shelf life.
  17. 17. After pressing groundnuts we got oil with suspended water and peanut particles which were allowed to precipitate by keeping it un-disturbed for three days. The oil standing above the precipitate was clear and got collected in a cleaned nylon can for storage.
  18. 18. The by-product of oil extraction is the oil-cake. It is an excellent fertilizer(high in nitrogen) and also a good cattle fodder.
  19. 19. Manually we removed the shell by beating and cleaning
  20. 20. conclusion: • We harvested groundnuts in volume of 3.5 gunny bags(85 kg rice bags) from 50 cents of land organically. • We got comparatively good yield we are planning to increase the cultivation area next season. • The plants were healthy and least attacked by diseases and pests since they had good immune system and good resistance to pest. We fenced the land completely with branches of thorny bushes and reduced cattle entry. • We came to know that groundnut shouldn’t be cultivated continuously in same land, so we have started to cultivate green gram in that place few days after plucking of groundnuts. We shall discuss about it in upcoming ppt’s.
