5. SRI: Historical background
• SRI was developed in Madagascar in the 1980s
through efforts of Fr. Henri de Laulaniè
• The System was developed slowly through farmer
experimentation, changing water application
techniques, crop spacings, and seedling age etc.
• Rice yields increased from 2 t/ha to 10, 12, even Fr. Henri De Laulanié
14 t/ha.
• Prof. Norman Uphoff helped out-scale SRI to other
countries
• SRI has been grown in
Madagascar , India, Philippines, Cambodia, Laos, Sri
Lanka, Sierra
Leone, Bangladesh, Gambia, Cuba, Nepal, Myanmar, Prof. Norman Uphoff
Thailand, Mali, Rwanda, …..
• Kenya was the 37th country in the world to adopt

SRI in 2009

6. What is SRI?
• SRI is a package of practices especially
developed to improve the productivity
of rice grown in paddies.
• Unlike the conventional method of
continuous flooding of paddy
fields, SRI involves intermittent
wetting and drying of paddies as well
as specific soil and agronomic
management practices.
What SRI is NOT
• SRI is not about growing upland rice
varieties
• SRI is not GMOs
• SRI does not modify the genetic 6

7. Components of SRI
SRI has seven major components (deviating from
conventional flooded paddy)
1. Transplanting very young seedlings, i.e., at 8 to 12
days old (instead of the conventional 3-4 weeks)
2. Raising the seedlings in un-flooded nurseries and
well-supplied with organic matter
3. Transplanting seedlings at wider spacings and in a
square pattern, usually 25x25 cm, giving roots and
leaves more space to grow
• Transplant seedlings quickly, carefully and shallow
– taking care to have minimum trauma to roots,

8. Comparing conventional paddy nursery with SRI practice
SRI requires
less seed
SRI dry nursery, and 8-day old seedling
Conventional flooded nursery
Transplanting conventional rice seedlings Transplanting SRI young seedling

9. Components of SRI contd…
4. Transplanting only one seedling per hill (NOT of clumps of
3-4 seedlings)
5. Alternate wetting and drying of the paddy field
(do not continuously flood the soil) to ensure aerating
of the root zone,
6. Weed control is preferably done with a simple
mechanical rotary weeder. This aerates the soil as
it eliminates weeds, giving better results than
either hand weeding or herbicides,
7. Providing as much organic matter as possible to the
soil.

11. Advantages of SRI - More yield for less inputs
1) SRI gives higher rice yields – compared
to conventional flooded paddies,
2) SRI requires less water, and can save
25-50% water used in irrigation
3) SRI uses less seed & farmers save up
to 80% of the cost of seed
4) SRI rice has a harder grain, thus less
breakage during milling, giving better
grain quality and higher price.
5) Nearly all rice varieties give higher
yield with SRI, but some high-yielding
varieties respond better than others.

12. Introducing SRI in Kenya
4/19/2012 12

13. Background to SRI efforts in Kenya
• SRI was introduced in Kenya at the Mwea Irrigation Scheme in July 2009
• Initial partners: JKUAT, NIB, AICAD, WB, WBI, MoA, MWI, KARI, Cornell
University (of USA), Mwea Irrigation Scheme/MIAD, farmers
• The first crop season Aug 2009-Jan 2010, only two pioneer farmers
accepted to do trials voluntarily & on-station research trials at MIAD –
supported by AICAD
• Within that time, training & awareness creation was done using the two
farmer trials, video conferences, special ladies’ training
• Jan-May 2010: farmers were trained by invited trainers from India &
Japan supported by World Bank Institute
• Since April 2010, JKUAT Innovation Fund has been supporting a 3-year
SRI research & capacity building project in Mwea.
• From June 2011, National Irrigation Board is supporting a 6-month
project to upscale SRI in 4 schemes, i.e., Ahero, West Kano, Bunyala
& Mwea.

15. Objectives of the SRI initiative in Kenya
The main objective is to facilitate the wide-scale adoption of SRI for
increased rice productivity, water savings and occupational health.
The specific objectives include to:
• Promote adoption of SRI for improved rice production
• Save water used in irrigation of paddy rice.
• Scientifically assess the adaptability of SRI in Mwea and other rice-
growing areas in Kenya
• Quantify the benefits of up-scaling SRI
• Determine the health and environmental impacts of SRI, e.g., effects
on mosquito survival
• Create awareness/advocacy for SRI among key stakeholders engaged
in the rice value chain (farmers, Government staff, private sector)
• Build the capacity of important actors (farmers, extension
workers, researchers).

31. Challenges faced
• Farmers’ traditional
mindset, addressing
skepticism and
thus, resistance
• The crop was not weeded
with rotary weeders
• The planting calendar affects
rice yields
• Shortage of SRI extension
workers
• A higher incidence of weeds
• Some farmers applying half-
SRI measures

32. Lessons Learnt
• The scientific basis for adoption of SRI has been proven
• Aggressive awareness creation and hands-on training has
resulted in good adoption rates.
• SRI message is now accepted in all 4 schemes
• There are many spin-off innovations, e.g., 3 local people
have fabricated rotary weeders
• Farmer behaviour has changed – most use less water
• Collaborative efforts & cost-sharing helped push the project
success
• Need to engage the private sector - interest by Numerical
Machining Complex to support developing rotary weeders
• Policy support helps – extending SRI to Ahero, West Kano &
Bunyala with NIB support

33. Way Forward
• Train extension workers to support SRI farmers
• Build capacity of farmers to do full SRI
• Develop rotary weeders suited to local conditions
• Raise funds to support farmers & the value chain
• Manage pests and diseases (preventive measures)
• Expand SRI to all rice-growing areas in Kenya and
hopefully, Africa.
• Collaborative research & outreach with other partners
• Achieve 100% adoption of SRI to grow more rice with
less water! 33 4/19/2012
