The Impact of Groundwater Irrigation Development on Cropping Intensity and Crop Productivity in Krishnagiri District

Aims: The study is done with the objective of assessing the impact of groundwater irrigation development on cropping intensity and crop productivity in Krishnagiri, Tamil Nadu, India. 
Study Design: Purposive random sampling 
Place and Duration of Study: Krishnagiri district, Tamil Nadu, India during 2019-20. 
Methodology: The data on irrigation sources and area under various irrigation sources in Krishnagiri, Tamil Nadu and India is subjected to growth analysis using trend studies and CAGR (Compound Annual Growth rate) to study the ground water irrigation development. Whereas, regression analysis was done with the primary data collected from 120 farming households in Krishnagiri on agricultural land use and irrigation to study the impact of groundwater irrigation on cropping intensity and crop productivity. 
Results: As the net tube wells and other well irrigated area to net sown area (GWA) increases, there has been a corresponding increase in cropping intensity and crop productivity. The rise in percent of net tank and canal irrigated area to net sown area and percent of fertilizer applied area to net sown area have also increased cropping intensity and crop productivity whereas the increase in percent of net rainfed area to net sown area have decreased the cropping intensity and crop productivity. 
Conclusion: The ground water utilization through tube well construction have increased the cropping intensity and crop productivity.
