Economic Impact of Cotton-Raya Relay Cropping on Crop Yield and Soil Health: A Strategic Approach to Climate Resilience and Profit Maximization

Abstract

Climate change, soil degradation, and depletion of natural resources challenge agricultural productivity and economic sustainability. Developing resilient agricultural systems is crucial for food security amid these changes. Relay cropping, where one plant species is inter-seeded into an established crop, maintains continuous plant cover, optimizes resource use, and enhances climate resilience. Therefore, the objective of research was to assess the economic benefits of relay cropping systems in enhancing crop yield and improving soil health. It aims to identify how these practices contribute to climate resilience and maximize farm profitability, offering strategic insights for sustainable agriculture in the face of climate change. Brassica (Raya/Mustard) was sown in standing cotton as a relay crop on first week of October- using 3 kg seed/acre, and also a sole crop to compare the results. Economic analysis over three seasons shows that relay cropping consistently achieved higher net profits compared to sole cropping. Results showed that in 2022-23, cotton relay cropping yielded higher with a net profit of Rs. 66,950, compared to sole cotton and a net profit of Rs. 39,200. Relay cropping also improved soil health, with higher soil organic matter levels observed; for example, in 2022-23, cotton relay cropping had 0.78% soil organic matter compared to 0.63% in sole cotton. Although sole cropping offered higher yields for Brassica, relay cropping resulted in better soil nutrient levels. Overall, the relay cropping system yielded a combined net profit of Rs. 130,630 in 2022-23. These findings highlight relay cropping’s potential to enhance farm profitability and sustainability by addressing resource use inefficiencies, reducing input costs, and stabilizing yields, making it a strategic choice for climate resilience and economic stability.
