Correlation between Irrigation Intensity and Cropping Intensity in Kongu Uplands, Tamil Nadu

Irrigation simply refers to the artificial way of supplying water to plants. It is a very important physical input in modern agriculture as the crop production of an area largely depends on the existing irrigation facilities. Its urgency needs emphasis for having a stable and successful agriculture in an area like the Kongu Uplands, where rainfall is seasonally distributed and unreliable. The study area has secured a good position in agricultural production in Tamil Nadu during the past two years and its irrigation has also increased but unevenly at block level. This paper attempts to find out the spatial pattern of irrigation intensity and also the relationship between irrigation intensity and cropping intensity in Kongu Uplands in blocks level for the year of 2015 -16. Karl Pearson’s Product moment of correlation coefficient method has been adopted to compute the relationship between irrigation intensity and cropping intensity. The block level G – return data has been collected from Economic and Statistical Departments of the respective districts for the year 2015 - 16. ArcGIS environment is employed for the preparing maps. Similar studies can be carried out in future with this same methodology as it facilitates the concerned authorities to make proper decisions.
