Abstract

Among 24 tree species tested for height and age relationship under agroforestry systems of northern dry zone of Karnataka, Gompertz model fitted well for 9 species, Weibull model for 7 species, Exponential model found well suited for 5 species and Richards model for 3 species respectively. Among the different models tried in predicting height growth for 24 different species Gompertz was found better for Acacia auriculiformis (R 2 = 0.9974), Acacia nilotica (R 2 = 0.9981), Bahunia purpurea (R 2 = 0.9971), Butea monosperma (R 2 = 0.9992), Casuarina equsitifolia (R 2 = 0.9914), Cassia siamea (R 2 = 0.9986), Inga dulce (R 2 = 0.9968), Samanea saman (R 2 = 0.9995), and Tamarindus indica (R 2 = 0.9976). Hence, Gompertz model can be best adopted while predicting height growth of native species grown under dry land situation.
