INTRODUCTION Agriculture plays a crucial role in providing food security and sustainability for the growing global population. To meet the increasing demand, modern agriculture needs to be more efficient, cost-effective, and sustainable. The advent of wireless communication, the Internet of Things, blockchain, and drone technology offers innovative solutions to address the challenges faced by the agricultural sector. A measure of environmentally friendly food production's persistence and sustainability is called sustainable agriculture [1]. In order to maintain farmers and resources, sustainable agriculture promotes agricultural methods and practises. It is Economically viable, it enhances land biodiversity, preserves water resources, lowers soil deterioration, and maintains a natural and healthy environment [2]. In order to protect natural resources, stop the loss of biodiversity, and cut greenhouse gas emissions, sustainable agriculture is crucial [3]. Sustainable agriculture is a way to increase farming productivity while maintaining the environment without fundamental necessities of the next generation. Crop rotation, the management of nutritional deficiencies in crops, the management of pests and
