Artificial Intelligence (AI) is rapidly transforming the agricultural sector by improving productivity, efficiency, and sustainability. Modern agriculture faces major challenges such as increasing food demand, climate change, water scarcity, and labor shortages. AI technologies including machine learning, robotics, drones, Internet of Things (IoT), and precision farming provide effective solutions to these challenges. AI helps farmers monitor crops, detect diseases, manage soil, optimize irrigation, and increase crop yield using data-driven approaches. This paper discusses the major applications, benefits, challenges, and future scope of AI in agriculture. The study concludes that AI has strong potential to revolutionize agriculture and ensure global food security in the future.
