years, ranging from 23 to 87. On average a household has access to 3.1 ha,<br />
ranging from 0.4 to 9.7 ha.<br />
To identify factors determining household differentiation <strong>and</strong> evaluate<br />
how they interact with characteristics of extension services <strong>and</strong> result in the<br />
observed performance, factor analysis was first carried out. Nonmetric<br />
variables were included using dummy variables. The procedure extracted 8<br />
factors with Eigen values greater than 1. The scree test showed that only the<br />
first three factors are significant <strong>and</strong> these were retained for further analysis.<br />
To interpret the factors the VARIMAX method was used to obtain orthogonal<br />
rotation of factors (Table 8).<br />
After rotating the factor axes, the variables with high statistically<br />
significant loadings on Factor 1 included number of members working on<br />
