One of the essential elements of sustainable agriculture in Dakshina Kannada involves Mixed cropping System. This cropping system includes various crops such as coconut, areca nut, banana, pineapple and pepper. This paper analyses the cost-benefit mechanisms of these structures, concentrating on their environmental, social, and economic consequences. Coconut-centred multi cropping utilises the corresponding expansion structures of intercrops, enhancing land usage and asset efficiency. Financial analysis examines the improved earning capacity of multi cropping due to diversified income avenues along with decrease in reliance on a mono plantation. Ecological advantages include enhanced soil health, dec5rease in soil erosion, and enhanced water maintenance, providing to enduring environmental balance. These structures offer enhanced job prospects and nourishment safety, encouraging flexibility in agrarian societies Moreover, disputes such as labour severity, increase in foundational costs, and wider market reach for multicrops pose challenges to implementation. Moreover, disputes such as pest and disease management, employee scarcities, and market price volatility pose restrictions to wider implementation. The results highlight the necessities for farmer training, targeted policy interventions, and infrastructure growth to unlock the full potential of integrated harvesting in the areas like Dakshina Kannada.
