Abstract
Computing the growth of any entity over a time period is important for understanding the past behaviour and for future planning. ‘Compound growth rate’ is one of the frequently used methods for calculating the growth rate models. Among the statistical study was carried out on different growth models viz., Linear, Quadratic, Cubic, Exponential, Compound, Logarithmic, Inverse, Power, Growth and S-Curve models to project the area, production and productivity cotton crop in Tamil Nadu for 1970-71 to 2012-13. The study revealed that through all models exhibited significant; the cubic model is the best fitted, for its highest adjustedR2 and exhibited decreasing future projection trends with respect to area and production of cotton. Although the productivity showed slightly increasing trends during the past and future.
