This scientific paper presents an in-depth analysis of the integration of mobile technology in agricultural extension services, illustrating its pivotal role in revolutionizing information dissemination and management in agriculture. It commences with a detailed overview of various mobile technologies such as smartphones, SMS, voice messaging, and mobile internet, and their profound impact on the agricultural sector. The study progresses to examine diverse modes of technology delivery, including direct communication methods like voice calls and SMS, multimedia approaches like videos and podcasts, and interactive services such as chatbots and forums. This is followed by an evaluation of the impact of these technologies on extension service delivery, focusing on their reach, speed, cost-effectiveness, and resource utilization, and how they compare to traditional extension methods. The paper provides empirical insights through case studies and real-world examples, including successful implementations like Kenya's M-Kilimo service and more challenging projects like Nigeria's AgroMobile, offering a nuanced understanding of the factors influencing success and failure. A comparative analysis is conducted to contextualize the use of mobile technology in agricultural extension services globally, considering different socio-economic and technological environments. The study concludes by exploring emerging trends and future innovations in mobile technology, such as artificial intelligence (AI) and the Internet of Things (IoT), and proposes strategic recommendations for enhancing its application in extension services. These recommendations include advancing digital literacy, tailoring technology to local contexts, and fostering supportive policy environments. This comprehensive examination underscores mobile technology's critical role in advancing agricultural practices, enhancing farmer engagement, and contributing to sustainable agricultural development.
