Technical Versus Institutional Innovation in Andalusian Olive Tree Orchards: An Adoption Modelling Analysis

A survey carried out among olive tree growers in different districts of southern Spain allows the identification and analysis of factors related with adoption of several technical and institutional innovations. At that respect, a composite numerical index has been performed including all innovations considered, among then the following: changes in orchard structure, non or reduced tillage, use of tree vibrators for harvesting, non conventional methods for fighting pests and diseases, keeping an accounting systems, annual farm planning, level of information and awareness of the European CMO in relation to olive oils, etc. Structural and managerial variables of the orchard and personal characteristics of the grower, related to the composite innovation index, have been identified. In a second step, two similar separate analysis have been made for both technical and institutional innovations, and several conclusions have, finally, been drawn concerning factors that should enhance both types of innovations adoption in Spanish olive orchards.
