Abstract
An analytical study was made in the Department of Agronomy, Tamil Nadu Agricultural University (TNAU), Coimbatore. The study was conducted for finding the identification of potential district of maize in Tamil Nadu based on the area, production, productivity data collected from 1998-1999 to 2015-2016. Based on the data relative spread index (RSI) and relative yield index (RYI) were calculated. The results showed that among 32 districts of Tamil Nadu five districts such as Ariyalur, Coimbatore, Erode, Theni, Tiruppur are very potential districts for cultivating the maize crop. From the analysis, parameters like RYI and RSI are high and these are potential districts and some districts are having RSI more but RYI less which indicates that non-suitability of the crop to that area.
Keywords: Relative Spread Index (RSI), Relative Yield Index (RYI).
