Organic Paddy

Updates

  • 2010-01-27
    • Gandakasala is ready for harvest, albeit 2 weeks behind schedule! A soil spoiled by nitrogen fertilizers needs time to recover and as expected, our yield is also much lower than what long-time organic farmers get. We expect about 15% crop loss due to erratic rains. But, many in the neighbourhood lost their entire crops. This only goes to show that Native varieties are the most simplest and best suited for our climatic conditions.
    • Since no mechanisation will be used, the harvest is expected to be more time consuming and that also translates to more cost.
    • Garudan samba, being a longer period crop, will be harvest in a couple more weeks.

Guiding Principles

  • Growth
    • Use native varieties of organic rice.
    • Record inputs costs viz
      • Seeds - name, cost / kg, kg reqd / acre
      • Manure - tipper loads / acre
      • Water usage in days (defined as the number of days we held water)
      • Labour costs
    • Use branches amidst the fields to attract birds
    • Organic pesticides
  • Processing
    • Process everything into rice, no polishing
    • return husk to soil
  • Storage
    • Home needs
    • Seeds for next cycle

Answers from Sither's

  • Q: What native variety of organic rice to grow for samba?
    • There are over 10 varieties of samba native rice
      • Mapillai Samba - medicinal qualities, low sugar content - fit for diabetics, more fibre content - constipation cure, etc.,
      • vellai ponni - “improved”, indigenous variety local to TN with a 145 days cycle
      • A lot more such as Kichadi Samba, Salem Samba, Neelanchamba, etc.,
  • Q: What is organic food?
    • Organic food has three broad principles
      1. Only resilient native varieties to be grown
      2. Increase soil biomass over a period of time
      3. Process food yourself; Local varieties are good for local conditions; Hence create a local market
  • Q: What about pests?
    • Plant trees for long term build-up of a eco-system involving birds, reptiles and other elements that keep pests in control
    • In the interim, stick 6-8 ft tall tree branches on the Varappu and in a few areas in the center of the paddy field. This will allow birds to catch insects more effectively.
    • Lots of varieties of other even seasonal grains must be broadcasted; Try to think “increasing biomass” than “yield”.
  • Q: How much to grow?
    • Given 1.5 acres total, split into meal needs + tiffin needs for a wholesome diet
    • vellai ponni for meal needs; Gandagasaala for tiffin
      • Vellai ponni is a native variety which has been “improved” in the name of “Ponni”. But this variety has its own unique flavour and has a 145 days life cycle.
      • Gandagasaala literally means “Is it enough food?” in Telugu. Apparently, it grows bountiful and has been a native for decades in the TN region too
    • How much to grow? Thumb rule: 30 kg / acre; But it depends on understanding your soil / eco-system conditions; I typically sow much less; When you begin, there would be a lot of work to be done
      • constant monitoring of pests
      • patiently studying manure needs and not filling it up with too much manure, etc.,
      • So… Study and proceed
  • Q: What is the Sow time to harvest time?
    • Varies by variety; details when we meet
  • Q: How different is the cultivation cycle?
    • Almost the same for all; One just needs to know what to expect - for instance, Karunkuruvai will turn black but insect laden 'hybrid' varieties turn black.
  • Q: Given I've not grown anything, how much manure should I add? Details please.
    • Collect as much green manure as you can, outgrowth from the road side and soak in moderate quantities of water held in the land; Let it rot and decompose over the period of seedling growth; Plough a little bit before casting seeds
    • Cow dung + cow urine + jaggery is an excellent way to get the microbial life kick started. Same treatment as above can be done for cow manure too
    • Roughly 15 tonnes of biomass must be added per acre for an average modern-style farmed land that needs repair; If you grew a plant and it failed, think “I added biomass” than “I lost my crop”.
    • This method builds long term stability - stop thinking like the central agencies that plan our “food production” with growth based goals.
  • Q: Pests and organic Pesticides / Pest control solutions. Directions to use (volume / proportions)
    • Already mentioned some aspects; We can talk about the details once we get there.

Input costs

Observations and areas of improvement

  • Before arrival of water, we could have arranged the cow manure
  • 25 KG / acre of rice seeds was in excess. Probably just 10-15 KGs would have sufficed.
  • Gandagasaala and Garudan Samba are probably not the most sellable varieties in our local market conditions (bangalore friends and relatives circles, chennai and thanjavur relatives circles)
