Abstract

In the context of global climate change and increasing demands on agricultural productivity, this study explores the integration of precision agronomy and climate-smart agricultural (CSA) practices as a viable approach to enhance crop yield and optimize resource use efficiency. A mixed-methods experimental design was employed to evaluate the combined effects of technologies such as sensor-based irrigation, variable rate nutrient application, conservation tillage, and remote sensing-guided crop management. Data collected from field trials, soil and plant laboratory analyses, real-time sensor outputs, and farmer feedback were synthesized to measure key indicators including crop yield, nitrogen use efficiency (NUE), water use efficiency (WUE), soil organic carbon, and microbial biomass activity. The results demonstrated that integrated precision and CSA strategies significantly outperformed conventional practices in terms of productivity and sustainability, with marked improvements in input-use efficiency and resilience to climatic variability. Figures and tables provided detailed visualizations of temporal trends in soil fertility, vegetative indices, biomass accumulation, and profitability outcomes. Additionally, positive feedback from participating farmers confirmed the socio-economic viability of these practices. This study not only validates the scientific merit of combining data-driven and environmentally sound agronomic methods but also contributes a scalable framework for sustainable intensification in agriculture. The findings highlight the potential of this integrative approach to support global food security, resource conservation, and climate adaptation goals.
