- 7. in IRAQ’s Al-Mishkhab Research Center, Najaf : SRI on left, Non-SRI on the right SRI practices induce a phenotypical change in rice SRI Conventional SRI SRI Conventional Conventional
- 13. Spread of SRI up to 1999 Madagascar
- 14. Before 1999: Madagascar 1999/2000: China, Indonesia 2000/01: Bangladesh, Cuba, Laos, Cambodia, Gambia, India, Nepal, Myanmar, Philippines, Sierra Leone, Sri Lanka, Thailand 2002/03: Benin, Guinea, Moz., Peru 2004/05: Senegal, Pakistan, Vietnam 2006: Burkina Faso, Bhutan, Iran, Iraq, Zambia 2007: Afghanistan, Brazil, Mali 2008: Rwanda, Costa Rica, Ecuador, Egypt, Ghana, Japan 2009: Malaysia, Timor Leste 2010: Kenya, DPRK, Panama, Haiti 2011 : Korea, Taiwan 2011: Benefits of SRI management now validated in 44 countries of Asia, Africa, and Latin America

- 19. 4 day seedlings, Indonesia
- 20. High tiller production when planted early SRI plants complete greater number of phyllochrons -- reaching 10 th phyllochron with SRI management vs. 8 th phyllochron with Traditional Practices (Thakur, 2010) A phyllochron is a regular interval of plant growth, ranging usually between 5 and 8 days for rice, when plant produces a unit of plant growth that induces tiller and root formation) SRI FP
- 21. Transplanting Careful and fast transplanting, shallow transplanting
- 22. Mechanization with SRI Transplanter for 1 seedling/hill (Tamil Nadu, India)
- 26. Motorized weeder

- 29. Faster growth - shorter crop cycle (10 days) Control SRI Plant development II SRI SRI Control Control
- 37. Mahto Oraon, Gumla district, Jharkhand state, India, with SRI plant having 65 tillers (Khandagiri, 110-day variety) RAINFED SRI: Adapting SRI principals to rainfed rice and other crops 50,000 farmers in Myanmar 130,000 farmers in Cambodia Central eastern States India
- 39. System of Finger Millet Intensification PRADAN, Jharkand, India
- 42. Sugarcane With SRI method Yields are by 20-50% improved 30% reduction in water use 25% reduction in chemical fertilizer Developed in India
- 44. Climate change impact on crop productivity Productivity trends for crops: Red: declining productivity Blue : increasing productivity Conditions for rice production will become more favorable in LAC compared to major rice producers in Asia – and compared to wheat, corn and soya

Notas do Editor
- Vietnam: October 2011: Over 1 Mio farmers (70% women) applying SRI on > 185,000 hectares India: 2011: 250,000 farmers Cambodia : 2010: 130,000 farmers; yield increases between 30-150%, Ministry of Agriculture included SRI in national strategy in 2006, SRI Secretariat to coordinate and promote SRI
- A phyllochron is a regular interval of plant growth, ranging usually between 5 and 8 days for rice. In this period, the plant produces one or more phytomers, each phytomer being a unit of plant growth in which a coordinated set of tiller, leaf and root that grow synchronously upward and downward from the plant's meristematic tissue, as described by Nemoto et al. (1995).
- Picture sent by Prativa Sundaray, staff member with the NGO PRADAN which is introducing SRI in poor communities, especially tribal ones in Orissa, Jhakhand and West Bengal, even where there is no irrigation, adapting SRI concepts to rainfed conditions.
- Picture from PRADAN – two plants on right have been grown with traditional methods; plant on left was grown with adapted SRI methods; plant on right is traditional local variety; two plants on left are both an improved variety (A-4040.
