On the basis of goodness of fit criteria (R2, MSE, RMSE and MAE), the best fitted model was chosen. And it was concluded that Logistic model was best fitted for almost all data sets of area and production of fruits in Hisar, Kurukshetra and Yamunanagar district as well as in Haryana state. The average annual growth rates for Mango, Guava and Citrus fruits in Haryana are 3.99%, 6.47%, 9.64% and for production it was 7.28%, 10.20%, 14.90% during the period 1990-91 to 2015-16.ennullThesis
