Main ideas, concepts, and lessons

  • Turmeric cultivation method (soilless, passive hydroponics):

    • Turmeric is grown without soil in a polyhouse using passive hydronics (passive hydroponics).
    • The root zone uses a water-holding, lightweight mix that supports good oxygen/CO₂ exchange while requiring much less water than traditional farming.

  • Farm setup and plant density (high population):

    • A large number of grow bags are placed inside the polyhouse to achieve a higher plant population, supporting higher yield.
    • Spacing is kept tight to maximize plant count while still maintaining sufficient aeration through the medium and structure.

  • Watering strategy (low and infrequent):

    • Plants receive water in a very short daily dose (about 5 minutes per day).
    • The approach emphasizes that too much water can be harmful, since the medium itself holds water.

  • Medium composition and its functions:

    • Commonly stated mixture proportions:
      • ~90% coco peat
      • ~5% perlite
      • ~5% vermiculite
    • Claimed roles:
      • Coco peat: holds moisture; improves aeration/irrigation balance.
      • Perlite: absorbs moisture and supplies it when roots require it.
      • Vermiculite: controls evaporation and helps maintain root-zone temperature.

  • Environmental control across cultivation types:

    • Polyhouse (best): helps maintain temperature and prevents excessive water ingress.
    • Net house (possible): may support shade-loving turmeric and can work well if rainy-season water is controlled.
    • Open field: yields less than the grow-bag system.

  • Variety and quality focus (curcumin content):

    • Lagdong variety is highlighted as giving:
      • ~7–8% curcumin (claimed)
      • Better overall yield compared with other varieties tested.
    • Curcumin is said to be higher after harvesting, and lower if measured mid-growth.

  • Organic inputs and certification claim:

    • Inputs include organic NPK plus other organic nutrient sources (e.g., organic calcium nitrate, organic potassium nitrate, wormy wash, cow dung).
    • Claims include organic certification via random lab testing.

  • Longevity and reuse of media (cost efficiency idea):

    • The coco peat grow-bag medium can be reused for multiple years (spoken as 4–6 years; “replace some quantity annually”).
    • A peroxide-based sanitization approach via drip channels is mentioned (instead of fully sterilizing media).

  • Claims on yield vs traditional farming:

    • The speaker suggests controlled conditions and optimized medium/plant density can substantially increase yield and curcumin percentage compared with traditional methods.

  • Harvesting, post-harvest, and storage:

    • Harvest involves carefully removing the plant/bag content, collecting rhizomes, then drying (solar drying mentioned).
    • Shelf-life claims:
      • Dry rhizome/powder: 6–7 months in normal conditions; longer with cold storage (up to 2–3 years stated for powder)
      • Wet rhizome: ~5–6 months

Methodology / operational instructions (detailed bullet list)

1) Establish the cultivation system

  • Use a polyhouse (preferred) for temperature control and to prevent excessive rain-water effects.
  • Implement passive hydroponics using grow bags and lightweight media (no soil).

Grow bag packing (example setup mentioned):

  • Bag size: referenced as 18 × 12 (units not fully clear).
  • Placement: ~35,000 grow bags in a ~1.25 acre polyhouse area (speaker’s estimate).
  • Media loading: fill each bag with ~5–6 kg coco peat (speaker also references dry loading and compressed vs non-compressed later).

Planting:

  • 2–3 plants per grow bag
  • Use rhizome pieces:
    • Rhizomes are cut into 3–4 pieces per bag.
  • Seed rate:
    • For “good quality seed,” about 1,000 kg per acre
    • Per bag: about 40–60 g rhizomes (speaker’s estimate)

Spacing:

  • Bed-to-bed: about 1 ft
  • Plant-to-plant: about 1 ft
  • Goal: maximize population while maintaining air access through the lightweight medium.

2) Media preparation (oxygen/root zone management)

  • Prepare the root medium blend:
    • ~90% coco peat
    • ~5% perlite
    • ~5% vermiculite
  • Claimed effect: improved root-zone aeration and moisture availability without soil compaction.

3) Watering schedule and parameters

  • Daily irrigation: provide water for ~5 minutes per day.
  • Water volume guidance: about ~70–80 ml per plant during watering.
  • Flow rate mention: described around ~4 LPH (also stated 2 LPH can work; even 1 LPH depending on delivery conditions).

Main principle:

  • Avoid overwatering because the medium already holds moisture.

4) Nutrition strategy (EC/pH/TDS targets + drip feeding)

  • Fertigation is delivered via drip (nutrients through drip irrigation).

Targets mentioned:

  • EC target: “below 2”
  • pH target: around 6.5–7
    • Rationale: turmeric prefers slightly acidic conditions; high pH can reduce nutrient uptake.
  • TDS guidance:
    • Fertilizer concentration mentioned as approximately ~1200 TDS
    • If water TDS is below ~300, normal water can still be used (speaker implies no AR/O filtration is needed in that case)

Organic nutrient sources referenced:

  • Organic NPK
  • Organic calcium nitrate
  • Organic potassium nitrate
  • Wormy wash (earthworm secretions liquid)
  • Cow dung
  • “Vermi wash” / earthworm liquids
  • Mentions “jiwamrutam panchagavia” as additional organic preparations

Key approach:

  • Match nutrient availability to pH/EC so roots can absorb effectively.

5) Cultivation timing (planting window and cycle)

  • Best planting months given: June–August (especially June/July/August).
  • Cycle duration in grow-bag method:
    • Mentioned as ~7.5 months (one segment of the discussion)
  • Seedling approach:
    • Direct seeding into grow bags (no nursery) is described in one key segment.
    • A transplanting approach is also mentioned as potentially reducing time by ~1 month (with nursery/control environment).

Seed placement:

  • Direct seed into grow bags.

Climate adjustment for Rajasthan-like extremes (hot summers/cold winters):

  • Start earlier:
    • Begin nursery outdoors around May (e.g., May 15–20 suggested)
    • Transplant/place into main grow bags around June or July
  • Use short-duration varieties:
    • Example: “Mega variety”
    • Mentioned duration: ~5–6 months traditional; ~4 months in grow-bag system
  • Harvest timing discussed:
    • Harvest in January in the proposed schedule

6) Weed and disease prevention practices

  • Use weed mat to suppress weeds.
  • Rationale given:
    • Weeds act as carriers for diseases
    • Weeds can also cause nutrient/water wastage by competing for resources
  • Drip delivery aims to reduce manual intervention.

7) Plant growth management

  • Avoid urea (speaker claims urea increases vegetative growth at the expense of reproductive growth).
  • Target plant height: ~5–6 ft
  • Air circulation concern:
    • Speaker argues it’s not a major issue due to:
      • tight spacing balanced by lightweight media and plant count
      • leaves not being dense enough to create problematic airflow blockage (as claimed)

8) Harvesting procedure

  • Harvest at the specified period (often stated around January for the discussed schedule).

Steps described:

  • Reverse/remove the bag carefully
  • Carefully remove the plant
  • Collect the rhizome
  • Re-place the bag (speaker indicates using the same bag again)
  • Post-harvest: solar drying recommended/mentioned to improve curcumin percentage

Labor estimate mentioned:

  • Two persons can manage harvest and related tasks.

9) Media reuse and maintenance

  • Coco peat medium reuse:
    • Mentioned as 4–5 years (and also “bags coming for 6 years”)
  • Annual top-up/replace:
    • Add ~1 to 1.5 kg extra media each year to compensate for losses during harvest
  • Sanitization:
    • Peroxide mentioned via drip channels as sufficient (instead of fully sterilizing media)

Quantitative claims / performance metrics (as stated)

  • Scale example:
    • ~1.25 acre polyhouse with ~35,000 grow bags
  • Yield:
    • ~3–4 kg per bag reported for the previous year (for Lagdong)
    • ~70 tons per acre stated as the highest last year; speaker expects higher this year
  • Pricing:
    • ~₹25,000 per quintal for dry product
    • Wet rhizome procurement by cosmetic industry mentioned at ₹30,000–35 per 100 kg
  • Curcumin:
    • Lagdong: ~7–8% (claimed)
    • Drying/harvesting timing affects measured curcumin
  • Drying recovery:
    • Around 20–22% dry recovery depending on variety; for Lagdong ~22%
