Comparative Analysis of Profitability, Water and Energy Productivity in Curry Leaf Cultivation: Drip vs. Conventional Production Systems in Coimbatore district, India

Abstract

The aim is to analyze the cost and returns of curry leaf production under different irrigation methods, assess water and energy productivity and draw conclusions regarding the sustainability and profitability of drip irrigation. The study utilizes a sample of 60 respondents from two blocks in Coimbatore district, employing a multi-stage random sampling technique. Primary data was collected through structured questionnaires administered via personal interviews between June and September 2023. Cost concepts were employed to calculate cultivation costs, while water and energy consumption were assessed to determine productivity. This study investigates the economic and environmental implications of adopting drip irrigation over conventional furrow irrigation for curry leaf cultivation in the Coimbatore district of Tamil Nadu, India. The results demonstrate that drip irrigation significantly reduces operational costs and improves yields compared to furrow irrigation. Gross and net incomes are substantially higher with drip irrigation, highlighting its economic advantages. Moreover, drip irrigation shows higher water and energy productivity, indicating its potential for resource conservation and sustainability. The results emphasize the importance of governmental support in promoting drip irrigation adoption to enhance water efficiency and facilitate value-added product export. In conclusion, this study highlights the significance of drip irrigation in enhancing profitability, conserving resources and promoting agricultural sustainability in curry leaf cultivation within the Coimbatore region.
