Based on SRI International Network and Resources Center, Cornell University,  the benefits of introducing SRI methods are

  • 20%-100% or more increased yields
  • Up to a 90% reduction in required seed
  • Up to 50% water savings

Field study by U-Tokyo researchers was held in two areas in 2011.

  1. Irrigated areas (Kampong Speu Province)
  2. Non-irrigated areas (Takeo Province)

And they checked that SRI contributed +20%~+70% yield for each areas.
