The statistical data from the agricultural department from the online sources for the past ten years are considered. The mathematical modelling techniques are applied to the observations obtained from the agriculture field. Yield of rice is modelled for the data taken. The method of least squares in Time Series Analysis (John 1984), (Meena, Subramanian and Gayathri 2014), (Gayathri and Subramanian 2016), (Somu 2015), (Yudo et. al. 2018) is considered. The linear equations are fitted for the state-wise average yield of crops in kg per hectare in India and also for the average yield of various principal crops in Tamil Nadu. The average yields of rice in India and also the variation of mean production of rice given in kg/hectare for the past ten years are computed. For the data taken in to consideration the co-efficient of variation of average yield of rice in India are evaluated. The mean yield of crops in Tamil Nadu for Rice, Jowar, Bajra, Maize, Ragi and Small Millets are calculated for the years from 2009 to 2014. The correlation coefficient (Efstathios 2018), (Siegfried, Piotr and Gilles 2018), (Hongyuan, Weidong, Zhou and Bernoulli 2018) between the actual yield and the expected yield of rice is graphically shown and it shows that the time series trend really depict the production of rice in India. Trend lines for the average yield of important crops in Tamil Nadu are obtained from the records of the agricultural survey. The expected yield of crops in Tamil Nadu for the years 2018-2024 are computed from the linear equations obtained from the linear Regression analysis. The obtained linear equations of the yield of rice in different states in India are useful to predict the growth and yield in upcoming years. The important crops yields are compared and the growths of crops in various states are compared. The modelling will be very much useful for the agricultural society to develop their production and profit.
