Agriculture remains as one of the most important economic sectors in Malaysia, which provides an employment for more than 1.6 million people. However, the growth of this sector can be hampered by a small-scale production, limited technological application, declining number of arable lands, environmental degradation due to climate change, rapid urbanization and aging farmers. In order to improve the competitiveness of agricultural sector, farmers are encouraged to fully utilize modern technologies in their farms. In this context, adoption of industrial revolution 4.0 (IR4.0) in an agricultural sector could offer many benefits, especially in minimizing the production costs and improving the quality of products. Thus, this review focuses on the adoption strategies of IR4.0 in an agricultural sector in Malaysia. A suitability of enabling technologies such as Internet of Things (IoT), autonomous robot, big data analytics and artificial intelligent. which are pillars for IR4.0 are individually evaluated. The readiness of the agricultural industry in Malaysia to embrace this new concept is also discussed. The review also investigates the potentials and possible challenges would be faced by the industry in embracing IR4.0. The recommendations are also targeted towards our fellow farmers, industrial players and policy makers to ensure a smooth adoption of IR4.0 in agricultural sector in Malaysia.
