2What is SRI?
- A system of irrigated rice crop management to
significantly increase production through changes
and integration of the management of rice plants,
soil, water and nutrients. - Does not depend upon high-cost modern inputs
- Reduces farmers costs of production
- Helps make crop production more sustainable and
is environment friendly - Easily accessible to resource-poor farmers
- Enhancement of food security
3Relevance to Bangladesh
- Rice is main staple crop 75 of cropped area
- High density of population small farm size,
majority of farmers resource-poor - HYV adoption increased production but yield
growth has leveled out, with reduced
profitability - Hybrid rice and biotechnology may increase
productivity but dependent on high- cost inputs - Biotech is still a debatable technology, with
possible health and environmental risk
4Rice Sector Needs of Bangladesh
- Substantial sustainable increase in yields to
release land for high-value crops - Reduction in cost of production increase in
profitability for farmers - Reduced requirement for high-cost inputs like
fertilizer, irrigation water, and insecticides - Environment- friendly sustainable agriculture
- SRI has shown the potential to meet all of these
needs of the BD agricultural sector
5SRI Trials in Bangladesh
- Started in 1999 after Bellagio Conference paper
on SRI reached BD - Dept. of Agric. Extension (DAE) and NGOs
conducted initial trials in farmers fields - BRRI conducted on-station trials
- Trials in farmers fields gave encouraging
results but BRRI onstation trials did not - Need for systematic evaluation -- PETRRA funded 3
sub-projects carried out over two consecutive
Boro season trials (2002 2004)
6 Findings from PETRRA evaluations
- Sub-Project 36 02
- Implemented by 3 NGOs (BRAC, SAFE, POSD) and a
private company (Syngenta BD Ltd.) - Participatory trials conducted in farmers fields
in 4 districts, 8 subdistricts (upazila) in
2002-03, N 487 farmers in 2003-04, N 791
farmers (plus 237) - Results for both seasons were found encouraging
- Number of participating farmers increased by 62
(111) during second year - Area under SRI increased by 91
7AGRONOMIC FINDINGS
- Tillers per hill were 95 higher during 1st
season and 60 higher during 2nd season than
under FP - Effective tillers were 94 and 122 higher during
the 2 seasons respectively - Length of panicle 11 higher in both seasons
- Weight of 1000 grains 14 18 higher

11Fig. 3 Comparative net returns, 2002 - 03
12ECONOMIC EVALUATION
- Because of reductions in the cost of production
while yield increased, farmers net returns were
increased more than 50 on average
13- Fig. 4 Comparative net returns, 2003 - 04
14Table 2 Profitability increase with SRI
15Perceptions of farmers on SRI
- No. of farmers and area under SRI increased
- Farmers confirmed increased yield from SRI
- Did not face any major pest/insect problems
- Thought that healthier SRI plants were more
resistant to pests/insects - Larger no. of farmers used organic manure but
needed training on preparing compost - Faced irrigation management problems these need
community approach to solve
16More perceptions of farmers on SRI
- Partial SRI adoption was favored by many farmers
in some areas accepting easier practices such
as early transplantation with reduced no. of
seedlings and wider spacing - Difficult practices included
- - applying compost or organic manure
- - alternate drying and wetting of fields
- However, even partial adoption had definite
positive effect on yield and profitability
17Findings from Sub-Project 34 02
- Implemented by BD Rice Research Institute (BRRI)
with local NGO partner - Trials were conducted in farmers fields in one
district (N 20 farmers, then 35) - Results for both seasons were positive no
detailed data on 2nd season - SRI results were found to be better than both FP
and BRRI practices
18Table 3 Agronomic performance
19Table 4 Comparative yields, returns, and BCR of
SRI, BRRI and FP
20SOCIO-ECONOMIC PERFORMANCE
- SRI yields and net returns were 49 higher than
FP and 4 higher than BRRI - Farmers perceptions in the area toward SRI were
positive also many farmers started their own
partial adoption of SRI - SRI was considered as specially suitable for
resource-poor farmers
21Findings from Sub-Project 35 02
- Implemented by BRRI with NGO partner in three
districts - Trials were conducted both on research station
and in farmers fields (N 32 farmers, and then
39 farmers) - SRI yields in one district were 17.5 higher
than under FP during 1st season - In 2nd season, SRI yields were 13 to 20 greater
22Further Findings from Sub-Project 35 02
- In the two other districts, 1st season SRI
yields were less than FP, but then they were
higher during the 2nd season - SRI costs were higher than FP in these trials
- - Labour costs 19 higher
- - Irrigation cost 33 higher
23Summary of SP 35 02 Findings
- Average net returns from SRI were similar to FP
- Many of the SRI practices were followed
incorrectly, which affected the results - Farmers perception of SRI was reported to be
mixed - However, farmer opinion was said to be universal
in favour of improved practices (modified SRI) - DAE and other extension organizations working
with project are showing interest to disseminate
SRI - Many local farmers have already started partial
adoption of SRI - Report recommends further field verification of
SRI
24SRI NATIONAL WORKSHOP, 2003
- Seven papers presented - 3 by BRRI staff, and
4 by NGO/ DAE extension specialists - Two BRRI papers did not have much positive to
report, but the 3rd was highly encouraging - NGO/ DAE papers found encouraging results
- Gap between views of scientists and extension
specialists was apparent - The farmers present expressed firmly positive
views on SRI
25WORKSHOP RECOMMENDATIONS
- Initiate integrated and coordinated approach to
evaluation and extension involving farmers,
scientists and extension workers ( GO/NGO) - Conduct further trials and experiments on SRI to
determine its potential in BD - Seek donor assistance for the above
26Some Limitations of SRI and Evaluation
- Trials were conducted for a short period
- Lack of proper understanding of SRI
- In some cases, faulty application was made of SRI
practices - Lack of organic manure
- Problems faced in irrigation management
- Proper weeding not done to save costs
- Cost-effectiveness required in weeding
27OVERALL FINDINGS ON SRI IN BD
- Overall experience shows encouraging picture
- Agronomic findings are favourable with more
tillers, effective tillers, larger panicles, more
filled grain, etc. - Grain quality was also found to be better
- Yield increases were significant in most cases,
up to 49 higher than yields with FP - Profitability was much higher, up to 82 more
- Farmers perception was highly positive many
also have adopted partial SRI on their own - Extension personnel (GO/NGO) have positive
attitude - Some scientists have taken a positive attitude,
some others are still skeptical no consensus
28CONCLUSION
- SRI has shown its potential for improving yield
and profits of farmers in Bangladesh - Gap still persists between results of researchers
on-station and farmers fields - Further trials and experimentation on various
aspects of SRI are needed - Government and donor support for more SRI
trials can be well justified - GO/NGO collaboration is also needed
