BANGLADESH: Reaping the Benefits: Training in Rice Growing System Ups Yields and Well-Being

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.

BANGLADESH: The Value of Information in Technology Adoption: Theory and Evidence from Bangladesh

BANGLADESH: The Value of Information in Technology Adoption: Theory and Evidence from Bangladesh | SRI Global News: February - April 2024 **sririce -- System of Rice Intensification | Scoop.it
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.

BANGLADESH: Experimental Evidence on Adoption and Impact of the System of Rice Intensification

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.

BANGLADESH: Performance of System of Rice Intensification with Conventional Method of Rice Cultivation | Bangladesh Agronomy Journal

BANGLADESH: Performance of System of Rice Intensification with Conventional Method of Rice Cultivation | Bangladesh Agronomy Journal | SRI Global News: February - April 2024 **sririce -- System of Rice Intensification | Scoop.it

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.
