Abstract

Brinjal (eggplant) plays a crucial role in income generation for smallholder farmers but faces severe yield losses due to the Eggplant Fruit and Shoot Borer. Since 2014, an insect-resistant genetically modified brinjal (Bt brinjal) has been available in Bangladesh, yet its adoption remains low, with many farmers discontinuing its use. To better understand the implementation of GM crops beyond initial adoption, this study examines the factors influencing farmers' intention to continue adopting Bt brinjal. Using an extended expectation confirmation model, this study investigates how pre-adoption factors, such as performance and effort expectancies, influence the (dis)confirmation of expectations and how post-adoption factors, including perceived usefulness and satisfaction, shape farmers' intention to continue Bt brinjal adoption. Based on a structured survey with 151 Bt brinjal adopters, the proposed model was tested using partial least squares structural equation modeling (PLS-SEM). Results reveal that pre-adoption performance and effort expectancies played a crucial role in shaping confirmation, which subsequently affected post-adoption perceived usefulness and satisfaction. Furthermore, satisfaction and perceived usefulness were key drivers of farmers' intentions to continue adopting Bt brinjal. The study contributes to the literature by integrating pre- and post-adoption constructs to explain continuance behavior and provides actionable insights for policymakers and stakeholders to enhance farmer satisfaction and long-term adoption of GM food crops.

孟加拉国农民继续种植Bt茄子的意愿:种植前后的驱动因素。
茄子在小农创收中发挥着至关重要的作用,但由于茄子果实和笋蛀虫,茄子面临严重的产量损失。自2014年以来,孟加拉国已经有了一种抗虫转基因茄子(Bt茄子),但它的采用率仍然很低,许多农民不再使用它。为了更好地了解转基因作物在初次种植之后的实施情况,本研究考察了影响农民继续种植Bt茄子意愿的因素。运用扩展的期望确认模型,本研究探讨了采用前因素(如绩效预期和努力预期)如何影响期望的(非)确认,以及采用后因素(包括感知有用性和满意度)如何影响农民继续采用茄子的意愿。基于对151个Bt茄子采用者的结构化调查,采用偏最小二乘结构方程模型(PLS-SEM)对该模型进行了验证。结果表明,采用前的绩效和努力预期在确认的形成中起着至关重要的作用,进而影响采用后的感知有用性和满意度。此外,满意度和感知有用性是农民继续采用Bt茄子的主要驱动因素。该研究通过整合采用前和采用后的结构来解释延续行为,并为政策制定者和利益相关者提供可操作的见解,以提高农民对转基因粮食作物的满意度和长期采用。

期刊介绍: Transgenic Research focusses on transgenic and genome edited higher organisms. Manuscripts emphasizing biotechnological applications are strongly encouraged. Intellectual property, ethical issues, societal impact and regulatory aspects also fall within the scope of the journal. Transgenic Research aims to bridge the gap between fundamental and applied science in molecular biology and biotechnology for the plant and animal academic and associated industry communities. Transgenic Research publishes -Original Papers -Reviews: Should critically summarize the current state-of-the-art of the subject in a dispassionate way. Authors are requested to contact a Board Member before submission. Reviews should not be descriptive; rather they should present the most up-to-date information on the subject in a dispassionate and critical way. Perspective Reviews which can address new or controversial aspects are encouraged. -Brief Communications: Should report significant developments in methodology and experimental transgenic higher organisms
