In this investigation an effort is made to fit a model for the height of different tree species and the yield of field crop. Here we have considered three trees species namely Ceiba pentandra, Terminalia bellarica, Mangifera indicia and soybean as field crop. The required data was collected from AICRP on agroforestry, UAS Dharwad. The different models were tried and the best two models were selected based on R2 and Standard error values. The best fitted models for height of Ceiba pentandra, Terminalia bellarica and Mangifera indicia were MMF model followed by Gompertz relation, MMF model followed by Weibull model and MMF model followed by polynomial. The results indicated that MMF model was found better for all the tree species. To predict the yield of field crop (soybean, at 1m distance) was increased in the beginning i.e. up to five years and then declining trend was notice. The best fitted models for the yield of soybean were, Rational model followed by Sinusoidal model in case of Ceiba pentandra, Rational model followed by Hoerl model for Terminalia bellarica, and Hoerl model followed by Rational model for Mangifera indicia.
