0411 Evaluation of SRI in Bangladesh

  1. 1. EVALUATION OF THE SYSTEM OF RICE INTENSIFICATION IN BANGLADESH Prof. A. M. Muazzam Husain BRAC University, Dhaka, Bangladesh WRRC, Tokyo-Tsukuba, Japan November 4-7, 2004
  2. 2. What 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
  3. 3. Relevance 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
  4. 4. Rice 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
  5. 5. SRI 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 on–station trials did not  Need for systematic evaluation -- PETRRA funded 3 sub-projects carried out over two consecutive Boro season trials (2002 – 2004)
  6. 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 sub–districts (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%
  7. 7. AGRONOMIC FINDINGS  Tillersper 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

  12. 12. ECONOMIC EVALUATION  Because of reductions in the cost of production while yield increased, farmers’ net returns were increased – more than 50% on average

  15. 15. Perceptions 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
  16. 16. More 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
  17. 17. Findings 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
  18. 18. Table 3: Agronomic performance Agronomic SRI BRRI FP features Panicles (m2) 296 270 226 Filled grains 78 65 52 per panicle Grain wt per No significant difference 1000 grains
  19. 19. Table 4: Comparative yields, returns, and BCR of SRI, BRRI and FP Indicator SRI BRRI FP Yield (t.ha-1) 6.03 5.79 4.06 Net returns (Tk 51,255 49,215 34,510 ha-1) Benefit-cost 1.9 1.8 1.3 ratio (BCR)
  20. 20. SOCIO-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
  21. 21. Findings 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
  22. 22. Further 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
  23. 23. Summary 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
  24. 24. SRI 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
  25. 25. WORKSHOP RECOMMENDATIONS  Initiateintegrated 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
  26. 26. Some 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
  27. 27. OVERALL 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
  28. 28. CONCLUSION  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
