Description

In most studies on forage quality, the rank of species and the interaction effect between species and time (grazing months) has not been analyzed for forage quality (Meshkani 1986). An additive main effect and multiplicative interaction (AMMI) model is able to analyse the interaction of species in the environment. Studies on stability of forage production have been carried out using the AMMI model (Farshadfar et al. 2010).

The objective of the current research was to determine the forage quality indicators of range species through AMMI models in semi-steppe rangelands of Karsanak area of Iran.
