Community Empowerment Project (CEP) – Daulatpur, Manikganj has successfully set up four System of Rice Intensification (SRI) demonstration plots in three Unions called Jionpur, Chakmirpur, and Kalia under Daulatpur. Besides that,188 farmers have implemented the SRI method in their 5,222 decimals (21.132 hectares) to increase rice production. The rice variety were mostly BR-28 and 29. Farmers are impressed to see their production and they promised next season they will implement in a vast area and also influence other farmers too.

Researchers conducted randomized trials of the System of Rice Intensification (SRI) agronomy method. Following SRI training of 5,486 Bangladeshi rice farmers, they compared trained and untrained farmers. The results showed compelling benefits for SRI's efficacy in increasing yield and profits, how it improves farming households' well-being, and its positive spillover effects in communities. This bolsters support for SRI's value, especially in the Global South.

This presentation, based on work carried out by Christopher B. Barrett, Asad Islam, Abdul Malek, Deb Pakrashi, and Ummul Ruthbah was presented by Dr. Barrett in Atlanta, Georgia, on July 21, 2019, at the USDA Multi-state Research Project NC-1034 annual research conference on the Economics of Agricultural Technology & Innovation.

Agriculture plays a powerful role in poverty reduction, according to a study done by BRAC’s research and evaluation division. The study revealed that the agricultural sector can reduce poverty-related sufferings faster than other sectors. ...BRAC’s programmes can start with integrating green technologies, such as a system of rice intensification (SRI), composting, organic fish feed preparation, fortified orange fleshed sweet potato cultivation, etc. A recent study shows a positive behavioural impact on participants – particularly adolescents – in adopting climate resilient livelihoods. BRAC has been practicing SRI in contextualised, environmentally friendly ways. For example, alternate wetting and drying is a good way to manage underground water. SRI also promotes other practices, such as the use of compost fertilizers rather than chemical fertilizers, and natural pest control system instead of chemical pesticides.

A field experiment was conducted in Sher-e-Bangla Agricultural University research field of Bangladesh during December 2012 to May 2013. This experiment was tested for two planting method consisting CM planting method (P1) and System of Rice Intensification (SRI) planting method (P2) against five rice (Oryza sativa) varieties named BR 16 (V1), BRRI dhan29 (V2), BRRI dhan50 (V3), BRRI hybrid dhan2 (V4) and Heera 4 (V5). All yield parameters showed the highest for SRI with higher effective tillers hill-1 (41.13), longer panicle (28.15 cm), higher total grains panicle-1 (216.89), number of filled grains panicle-1 (166.82) as a result 10.17and 12.5% higher grain yield and straw yield, respectively were observed in SRI than the conventional method.

Recommendations to raise yields with SRI methods for Boro rice in Bangladesh in this presentation at the 17th Australian Agronomy Conference( Sept. 24, 2015) include: Transplanting from 30 Nov. to 15 Dec. (for long-duration Boro rice) with 12-day-old seedlings (preferably raised in compost bed); wider spacing of 30 cm × 25cm; SRI irrigation management; "soil stirring" at 15, 30 and 45 DAT; and integrated use of fertilizer plus manure at 10 t ha-1 using the recommended rate for inorganic fertilizers.

[September 20, 2021] Gopal Chowhan, Member SRI National Network Bangladesh (SRINNB), recently reported on the progress of the NGO ADRA's decade-long promotion of SRI in Mymensingh and Manikganj regions of Bangladesh. ADRA's SRI activities, which use Participatory Action Research (PAR) approaches, are carried out in collaboration with the Department of Agricultural Extension (DAE) of Ministry of Agriculture. ADRA’s program staff provided farmer training and SRI demonstrations and subsequently shared results during the crop harvest with community farmers. The higher yield obtained in the SRI fields compared to traditional fields surprised farmers, and encouraged them to adopt SRI methods.

We report the results of the first large-scale, multi-year experimental evaluation of the System of Rice Intensification (SRI). Using a randomized training saturation design, we find that greater cross-sectional or intertemporal intensity of training exposure to SRI has a sizable effect on Bangladeshi farmers’ propensity to adopt (and not to disadopt) SRI. There is significant spillover learning from trained to untrained farmers. We find large, positive and significant impacts of SRI training on rice yields, revenues, costs, and profits for both trained and untrained farmers in training villages. We also find strong positive impacts on various household well-being indicators. Despite the significant impacts on rice productivity and labor costs, we find no evidence of significant general equilibrium effects on rice prices or wage rates. We also find high rates of disadoption, and clear indications of non-random selection into technology adoption conditional on randomized exposure to training.

We develop a theoretical model in which adoption decisions are based on information received from others about the quality of a new technology and on their risk attitude. We test the predictions of this model using a field experiment in Bangladesh. We show that treated farmers who receive better training in System of Rice Intensification (SRI) technology have more accurate information about this technology, and have a higher impact on the adoption rate of untreated farmers. We also find that untreated farmers that are more risk-averse tend to adopt less and are less influenced by their treated peers. Finally, a trained farmers' impact on his untrained peers increases if he himself adopts SRI technology. Our results indicate that the crucial determinant of technology adoption for untreated farmers is their degree of risk aversion and the accuracy and reliability of information transmission about the quality of technology circulated among farmers.

...We provided farmers with training on SRI and taught them how to apply techniques to their farms. ..We examine whether and how a farmer's decision to adopt a new technology depends upon the adoption decision of other farmers in his social group, and whether financial incentives play any role in selecting good quality of farmers who are more likely to adopt the SRI... Our results suggest that social networks at the village level could play a significant role in adoption and diffusion of new technologies, especially in the context of rice farming. ..We met both DGs of the DAE and the BRRI and scientists and research officers to share our findings with them. The DAE can help expand the SRI adoption. The BRRI also can help scale it up in different regions in different seasons...

The main objective of this study is to understand the network characteristics and incentive mechanism for successful adoption and diffusion of SRI. The yield gains are 14-25%. Though some additional labor is needed and the cost is higher, profit (as much as 33%) remains significantly higher than the traditional farming despite some less-than-perfect adoption of SRI. The main constraint for adoption appears to be managing the irrigation, which requires collaboration among farmers nearby for pumping at the same time. It is not clear whether adoption resulting from a one-time intervention would be sustained and if other farmers would follow suit upon seeing their success. Further studies are underway.
