This study aims to identify and analyze the major determinants that affect the adoption choice, rate and intensity of water-saving irrigation technologies (sprinkler and drip irrigation techniques) available in the western part of the irrigated perimeter of Mitidja Plain, Algeria. A sample of 136 farmers (28.75%) was randomly selected and surveyed using a structured questionnaire. Three econometric models were used, namely the Logit, Tobit and Poisson regression models. The main findings of the resulted models indicated that capital constraints (credit access, investment costs and subsidies) along with some human capital aspects (age, educational level) and water extraction cost, are the main determinants expected to influence the WSIT adoption choice, rate and intensity in the study area. These results will help to prioritize the factors that affect adoption decisions and provide insights for improving the crop and water productivity.
