  A chatbot is a software developed to help reply to text or voice
conversations automatically and quickly in real time. In the agriculture
sector, the existing smart agriculture systems just use data from sensing and
internet of things (IoT) technologies that exclude crop cultivation knowledge
to support decision-making by farmers. To enhance this, the chatbot application
can be an assistant to farmers to provide crop cultivation knowledge.
Consequently, we propose the LINE chatbot application as an information and
knowledge representation providing crop cultivation recommendations to farmers.
It works with smart agriculture and recommendation systems. Our proposed LINE
chatbot application consists of five main functions (start/stop menu, main
page, drip irri gation page, mist irrigation page, and monitor page). Farmers
will receive information for data monitoring to support their decision-making.
Moreover, they can control the irrigation system via the LINE chatbot.
Furthermore, farmers can ask questions relevant to the crop environment via a
chat box. After implementing our proposed chatbot, farmers are very satisfied
with the application, scoring a 96% satisfaction score. However, in terms of
asking questions via chat box, this LINE chatbot application is a rule-based
bot or script bot. Farmers have to type in the correct keywords as prescribed,
otherwise they won't get a response from the chatbots. In the future, we will
enhance the asking function of our LINE chatbot to be an intelligent bot.
