Introduction

Agriculture is undergoing a rapid technological transformation driven by the need to enhance productivity while minimizing environmental degradation and ensuring long-term sustainability (Foley et al., 2011) [8] . In India, the agricultural sector plays a crucial role in supporting livelihoods and ensuring food security, yet it faces persistent challenges such as climate variability, soil degradation, and inefficient resource utilization (Pingali et al., 2019) [19] . Traditional farming practices, which rely heavily on manual labor and generalized input application, are increasingly inadequate to meet the demands of a growing population and changing climatic conditions (Godfray et al., 2010) [10] . The emergence of Agriculture 5.0 represents a paradigm shift characterized by the integration of advanced digital technologies such as artificial intelligence, Internet of Things, robotics, and big data analytics into agricultural systems (Xu et al., 2021) [24] . This approach builds upon earlier agricultural revolutions by emphasizing human-machine collaboration, sustainability, and data-driven decision-making processes. The adoption of Agriculture 5.0 technologies has the potential to transform Indian agriculture by enabling precise and efficient management of resources, thereby improving productivity and resilience (Kamilaris & Prenafeta-Boldú, 2018) [12] . Recent advancements in AI have enabled the development of predictive models that can analyze large datasets to optimize crop management practices and reduce uncertainties in farming operations (Liakos et al., 2018) [14] . Similarly, IoT-based systems facilitate real-time monitoring of soil and environmental parameters, allowing farmers to make informed decisions regarding irrigation, fertilization, and pest management (Wolfert et al., 2017) [23] . (Wolfert et al., 2017) [23] . Despite these technological advancements, the adoption of Agriculture 5.0 in India is constrained by factors such as limited digital infrastructure, lack of technical expertise, and high initial investment costs (Klerkx et al., 2019) [13] . Furthermore, issues related to data interoperability and governance pose significant challenges to the effective implementation of digital agriculture systems (Verdouw et al., 2016) [22] . Therefore, there is a critical need to synthesize existing research on Agriculture 5.0 and evaluate its potential for addressing the challenges faced by Indian agriculture (Rose et al., 2018) [20] .

Conceptual
