Technology 4.0 is understood quite uniformly as the fourth-generation breakthrough technologies combined from achievements in the fields of digitization, physics and biological technology. As can be seen, the core of Industry 4.0 is the software industry to collect data, digitize and analyze databases, connect things, and make intelligent decisions from analysis results. The software industry is installed on the hardware industry (it can be the second and third generation technology) creating a breakthrough and affecting the production process of industries and fields in socio-economic life. human society.

• - In recent years, the trend of applying Industry 4.0 in the field of crop production is increasingly shaping and developing in Vietnam. It can be seen that most of the basic Industry 4.0 groups in agriculture have been deployed or started to be tested in our country. In which, the technologies that are being applied the most are digitized machinery and equipment systems, mounted with sensors and connected to the internet (IoT sensors) and/or combined with greenhouses, greenhouses, and greenhouses. greenhouse to form an indoor smart farming system, controlled automatically or semi-automatically with a closed process. In some enterprises, concentrated production farms, relatively large scale, these industries are being applied quite synchronously.
• - In addition to sensor technology, indoor smart farming systems, and LED monochromatic lights to provide enough light to promote plant growth, have also been applied in many barn growing facilities. longan from Binh Thuan to Tien Giang, or in mushroom production and flower growing in some localities such as Ba Ria-Vung Tau, Hanoi. Software applications in managing and monitoring the production and distribution of crop products have also been put into application at many agricultural production facilities in many provinces and cities.

Opportunities and benefits from the application of 4.0 technology in agriculture are clear. However, to take advantage of 4.0 technology, there are many challenges that need to be overcome.

• - Firstly, the scale of agricultural production is small, fragmented and scattered along with the initial investment cost for the application of Industry 4.0 in agricultural production which is often much higher than the normal production cost, so people are afraid to invest. difficult to attract investment in the application of Industry 4.0 in agricultural production.
• - Second, product market management is lax, enforcement of regulations on quality control, certification, product labeling and food safety is still weak in the country. This has caused unfair competition for products with high technology application when equating quality products with less quality products.

• - Third, agricultural development 4.0 requires a high-quality labor source. In fact, in Vietnam, the source of high-quality labor, knowledgeable about science and technology in agriculture is still lacking and weak, greatly affecting access to modern science and technology. This is one of the important factors creating great challenges when implementing high-tech agricultural programs, especially in regions with difficult socio-economic conditions.
• - Fourth, the issue of climate change is happening fast and strongly, epidemics are becoming more and more complicated and unpredictable, which has had a great impact on analysis and forecasting to achieve absolute accuracy. This problem makes it difficult for technology to analyze and forecast natural factors to operate optimally and to keep pace with the intensity and unpredictable developments of weather and epidemics.
