## 2 Materials and Methods  
Researchers have even proposed a new technology known as game engine technology [10]. The game engine is software designed for the sole purpose of video games. The possibility of using this technology in agriculture has been confirmed. With the emergence of complex situations prevalent worldwide, a new concept called digital teaching has emerged [11].  
Teaching agricultural courses online is strongly recommended by many researchers. They argue that in the future agriculture system, 3D technology will occupy an irreplaceable position [12]. Learning 3D technology in agriculture will be fruitful for students in many ways. Researchers have even analyzed a coconut plantation using 3D technology. It was a meticulous research analyst that stated that by using various images of plants in 3D form, one can obtain factual information about the number of trees, the status of ripe fruits, and the state of unproductive old coconut palms by just sitting in one place. These researchers are of the staunchest opinion that the use of 3D technology in farming is arguably the best [13]. Hence, the second is the idea of teaching agriculture online. Some even say that prerecorded videos will also benefit the students in learning agriculture online in the wake of extraordinary situations. Using artificial intelligence in the teaching of agricultural courses based on BP neural networks is an emerging trend. The type of soil plays a significant role in farming. Soil moisture predictions can be made using a BP neural network [14]. The accuracy of the prediction generated by the model is excellent. The artificial neural network is used to build the mathematical prediction model for soil moisture [15].  
In China, the needs for professional agricultural courses in higher education need to be matched with student realization of the value of higher education in meeting the needs of China's structural transformation and industrial growth. This can be supported by having educators in different colleges connect employers with updated prerequisites. In this regard, pilot research was carried out using multimedia to help teachers remove their educational aim, which was to produce graduates who are already capable of meeting societal criteria.  
Agriculture is required for humans to survive through food. Agriculture is an important sector that requires financial support and awareness to develop the industry. Through education, agricultural awareness can be improved, helping the industry to grow. The traditional agriculture course involves abundant fieldwork. During complex situations, fieldwork education will be limited. Modern technological developments can aid in overcoming these challenges. Students also have to be encouraged to register for vocational agricultural courses. Additionally, students and teachers should be given training in how to make use of trending technologies.  
The teacher and student will meet each other using interactive devices such as mobile phones, laptops, personal computers, etc. The teacher will either prerecord lessons and store them in a database or perform live online classes to deliver the course. To make the session interactive, the teacher will use some teaching tools and specific applications to elaborate on the processes involved in agriculture throughout the presentation. Agriculture is very much a practical subject and can use virtual technologies to visualize real-time agriculture. These processes are depicted in Figure 1.
