Two main models have been used to analyse farmers’ decisions to

(UM) and the second is based on the theory of planned behaviour (TPB). This
study uses a vote-count method to identify the effect of different variables on
farmers’ adoption decisions in 36 studies using either UM or the TPB. Results
from the UM studies show that the explanatory variables mostly have an
insignificant effect on the adoption decision. When the effects are significant,
the sign of the effect is inconsistent across studies. Results from the TPB
studies show that correlations between the psychological constructs used in this
type of model are significant in most cases. However, most variables are only
used in one or two studies and it is therefore not
