Introduction

• Rice is Life 44 of population depends on rice.
  We need to produce 127 million tonnes by 2025 and
  180 million tonnes by 2050.

SRI over Conventional

• Water is the Elixir of Life.
• Rice crop requires more water
• By SRI, in 10 area, if we save 20,30 and 40
  water, 500,740 and 1000 million mm is saved. A
  huge amount of money saved.
• That means, additional 0.4 mha rice can be grown
  or 2-3 times of other cereals.
• Seed saving 20 kg/ha
• Five times less hybrid seed is used lower seed
  requirement in SRI.
• Less chemical fertiliser in SRI.
• No chemical control of pests and diseases.
• More Yield in SRI

Benefit Analysis
SRI is beneficial to farmers. By converting, 10

Conclusions and Recommendations

• SRI method is the solution for increase in rice
  production and productivity.
• Resources like water, seed, chemical ferilizers
  can be saved.
• Increased production, productivity and benefit
  cost ration by adopting SRI.
• Large scale adoption may be recommended by
  policy advisors to meet food security with lower
  resources.
