The comparison of feasibility equation models of Variable Rate Technology-Irrigation in Fars and Khuzestan provinces

Variable Rate Technology-Irrigation (VRT-Irrigation) is a new approach of IT in agriculture to increase water efficiency in agriculture. With the application of VRT-Irrigation, water is used only in parts of farm that is needed. The purpose of this paper is to compare behavioral intention and attitude of agricultural experts in Fars and Khuzestan agricultural organizations toward VRT-Irrigation based on revised technology acceptance model (TAM). A survey was conducted using stratified random sampling to collect data from 135 and 114 experts in Fars and Khuzestan provinces, respectively. The results showed research models in this study are more powerful to predict behavioral intention and attitude than prior models. Based on the results, the independent variables have the difference power to predict intention to use, attitude to use and perceived usefulness of VRT-Irrigation in two provinces. There is not difference between two provinces regarding perceived usefulness. Based on the results some recommendations have been provided to use VRT-Irrigation in Iran.
