Abstract/ Executive Summary:

Sustainable adoption of promising technology leads to increase yield and productivity of rice significantly. Yield gap reduction through minimization of the adoption cycle of rice technologies is essential to increase the food security of Bangladesh. Adoption of promising rice variety required 16±3 years to reach its adoption peak at farm level following the existing dissemination protocol. The specific objective is to find out the ways and means to curtail the adoption lag of variety, management practices, and rice-based technologies for sustainable food security of Bangladesh. The study is accomplished accordingly by reviewing previous works completed on technology adoption; calculation and estimation of future seed demand and supply. Our findings reveal that the average yield gap between actual farm yield and potential farm yield is 20.7%. Seed retention and motivated farmers estimated from the frontline demonstrations of BRRI were 18 and 20%, respectively. Sufficient amounts (128 kg/variety) of breeder seed need to be produced by the concerned research organizations concurrently the variety release process. The seed will be used to execute an action plan by setting up 64 adaptive trials (AT) in 64 districts to select location-specific suitable variety(s) for rapid dissemination. In the 2nd and 3rd years, 256 kg quality seeds per variety will be required to conduct 128 AT/SPDP in 64 districts. The seed of farmers’ chosen variety(s) will be collected, stored, and marketed by the local seed producer or farmers group; and they will provide this information to the extension organization and BRRI. At least 10 to 20% of seed selling information will be checked by the concerned scientist of BRRI every year and total seed selling data will be calibrated based on the checked data. Similarly, the next two years’ trial data will be collected from conducted trials and associated seed producer/dealer/farmers’ club/groups. Then, the concerned research institute will be able to provide a projection of diffusion rate and demand of newly released variety(s) compiling three years of data. Based on the authentic reports, the concerned organizations will conduct block, frontline, and follow-up demonstrations in collaboration with all the stakeholders. Action plan of research and extension; large scale frontline demonstration of the selected variety(s) with more stakeholders followed by field day, training, and workshop would be the key drivers for effective and sustainable dissemination of technology lead to reduce adoption lag effectively. Combined initiatives and integrated approaches need to be taken nationally to execute the adoption lag minimization plans and model for rapid dissemination of promising technology to doubling the rice productivity. Therefore, popularization and adoption of new technology would be possible within five to seven years instead of 16±3 years.

Program Area: Variety and Species

Commodity: Rice, Rice

Objectives:

To formulate a guideline to minimize the adoption lag of rice variety and to develop an action plan for reducing adoption lag to doubling rice productivity and increase food security.

Methodology:

The study was accomplished accordingly by reviewing previous works and studies completed on technology adoption. Calculation and estimation of future seed demand and supply accomplished through the temporal pathway. The data used in this study were obtained from scientists, extension personnel, and farmers. During the variety release process, at least 128 kg breeder or quality seeds per variety need to be produced by the concerned research institute for executing an action plan. After execution of the action plan and varietal diffusion model, adoption lag will be minimized by 5 to 7 years of variety release. Moreover, the seed production and dissemination status of the Adaptive Research Division was presented through reviewing the annual report 2000-2001 to 2019-2020 of BRRI. Adoption means bring it up on one’s own or choosing to take it up. Adoption lag denotes falling behind or follows after a delay to receive technology. Adoption lag is defined by the time difference between releasing technology and its reach to the adoption peak that expressed as a year (Kabir et al., 2015). The time lag between the release and farm-level adoption of the new varieties needs to be reduced (Singh, 2013). Adoption system enhancement is very much important to minimize adoption lag. Two major components are the keys to adoption lag minimization. A diagram with major components for adoption lag minimization is given below.

Achievement/Findings:

Technology dissemination with integrated approaches like an authentic and multi-stakeholder evaluation of advanced genotypes or component technology, adequate field applicable demonstration of the technology, proper adoption plan based on diffusion information, and speedy availability of seeds to farmers would boost up technology adoption for minimizing adoption lag. Adoption of newly released rice varieties would be possible within five to seven years if the formulated action plan and adoption lag minimization models could be practiced. Combined efforts of farmers, researchers, extension personnel, and the Government of Bangladesh would be enabled to minimize adoption lag by 2030 that could be a vital role in doubling rice productivity and sustainable food security.
