Agricultural extension systems have long served as an essential link between agricultural research institutions and farming communities by facilitating the transfer of improved technologies, knowledge, and farming practices. The primary aim of extension services has been to enhance agricultural productivity, strengthen farmer capacities, and improve rural livelihoods through education, training, and advisory support. Over the decades, extension systems have undergone significant changes in response to evolving agricultural challenges, policy reforms, and technological advancements.In the early stages, agricultural extension services were largely government-led and focused on increasing crop production through dissemination of improved crop varieties, chemical fertilizers, irrigation techniques, and pest management practices [4]. Extension personnel conducted field visits, organized demonstrations, and trained farmers to adopt recommended practices. This approach played a crucial role during the Green Revolution period, contributing to increased food production and improved food security. However, the traditional model often followed a top-down approach, where recommendations were standardized and sometimes failed to consider local agroecological and socio-economic conditions. Additionally, limited manpower, logistical challenges, and insufficient follow-up support restricted the outreach and effectiveness of these services, especially in remote rural regions.As farming challenges became more diverse and complex, extension approaches gradually shifted towards participatory and farmer-centered models. Farmers were increasingly recognized as active partners rather than passive recipients of knowledge. Participatory approaches such as Farmer Field Schools and community-based learning methods encouraged farmers to experiment, share experiences, and develop local solutions to agricultural problems [5]. These methods enhanced farmer confidence and improved decision-making skills, leading to better adoption of improved practices. However, participatory approaches required significant institutional support and continuous engagement, which sometimes limited large-scale implementation.With economic liberalization and increased commercialization of agriculture, private sector organizations, non-governmental organizations, cooperatives, and agribusiness companies also began participating in extension delivery. This led to the development of pluralistic extension systems involving multiple stakeholders. Input suppliers and agri-service providers started offering advisory services alongside their products, thereby expanding access to information and services. While this broadened extension outreach, it sometimes raised concerns regarding commercial bias and unequal access for small and marginal farmers who might not afford private advisory services.

The emergence of information and communication technologies marked another major transformation in extension delivery. Initially, radio and television programs served as mass communication tools to disseminate agricultural information. Later, the expansion of mobile phone connectivity significantly enhanced farmers’ access to timely advisories. Services providing SMS alerts, voice-based advisories, and call center support enabled farmers to receive information related to weather forecasts, pest outbreaks, and crop management. These digital communication channels reduced information gaps and improved outreach efficiency, although adoption varied depending on digital literacy and infrastructure availability [6]. In recent years, rapid advancements in digital agriculture technologies have further reshaped extension systems.
