In the era of 21st century, agriculture is facing many challenges now-a-days to feed the world population. The population growth is increasing day by day and it expected to cross 10 billion by 2050. Agriculture farming plays significant role in growth of Indian economy. India stands second in farm production all over the world. After the green revolution, India face production loss with an estimate of US$ 36 billion. The agriculture production decreases mainly because of insect pests, diseases and weeds in important agricultural crops. Hence, there is a need of transition in farming system to adopt advanced and innovative technologies for more and sustainable production. In recent years Artificial intelligence gained popularity in agriculture and provides solutions in several areas like big data analysis, pest and disease forewarning models, mobile applications in IPM, Information and ICT based crop-advisory system, insect detection, pest and disease identification, etc. In the proposed paper, AI based applications discussed in detail to provide insights into innovative technologies and pave the way for knowledge dissemination and adoption of AI based technologies for more effective crop production and protection.
