    • Photos from Oct. 2009 visit to SRI field in Tamil Nadu, India (by Mei Xie, WBI)
      SRI was piloted from 2000-2004 by TN University of Agriculture – a leading agriculture institute in India
      After successful trials by TNAU, it was included in WB project from 2006 to now. Many farmers have now tried 4-5 seasons of SRI. Liked it much. Results were impressive – over 30% water saving, with 30-60% or even more increase in yields, and labor saving.
      Local governments give strong support, with scientific and research back-up from TN agricultural university
      Now over 500,000 ha under SRI management in the state. Still expanding
    • Manual transplanting and manual weeding with conoweeder are used by most farmers
      Female labor does most of the transplanting, using thread with knots to mark the field – not accurately square however
    • Conoweeder – easily made by locals, easy to use
      Disassembled conoweeder;design to be sent to Kenya farmers/MIAD
    • Mechanized transplanting and weeding were tried this season – expect to have major breakthrough in labor saving. Expect this to spread fast among farmers
      Developed by private sector who got contract from WB project. Transplanting machine modified from China imported transplanter
      Weeder also was developed by private sector. It is liked by farmers.
    • Extension Support by TN Agriculture University
      SRI field
      Over 300 Master degree students got posted in villages for 3 yrs to help disseminate SRI
    • SRI roots more developed than traditionally grown paddy
      SRI
      Non-SRI
      Field Comparison
    • Allow soils to crack before irrigating again
    • Green manure planted 30 days prior to paddy field preparation – as organic fertilizer
      Dan ji - a kind of legume -
      shown by Dr. Ravi of TNUA
      Plough back into field as excellent green manure, reduce chemical fertilizer use
    • Nursery
      Smaller nursery bed s are needed, and are next to the field – convenient to farmers
      14-day seedlings asresuggested in Tamil Nadu. Younger ones can result in higher yields, but are more difficult for farmers to handle during transplanting
    • Farmers ‘ reaction to SRI
      When asked in the field “Who are using SRI?” many hands were up
      This farmer had composed a song for SRI – telling others how to transplant, how to weed, and how to water ….
    • Harvesting – Witnessed measuring paddy yields – SRI 2 tons higher in yield than conventional paddy
    • TNAU is studying reduction of GHG release by SRI field – over 20% reduction by SRI compared to conventional rice fields – results to come out soon
