Alternate Wetting and Drying (AWD) is a simple and low cost water saving technology for helping farmers to cope up with the increasing water scarcity in irrigated environment. Irrigation is regulated by intermittent flooding in rice field with the help of Pani Pipe (perforated field tube). The study was carried out in Puri District of Odisha to ascertain the constraints perceived by the farmers that inhibit the adoption of AWD technology. All the selected farmers involved in adoption of AWD were interviewed as respondents. Different constraints social, technological, economical, organizational, ecological, biophysical etc. were prioritized on the basis of mean score and rank order analysis. Lack of awareness about new technology, lack of proper weed management knowledge, high cost for weed control in adoption of AWD, inadequate extension activities to develop confidence, presence of undulated land and lack of irrigation channels were the major constraints as per the farmers’ perception. Suggestions were given for large scale adoption of the technology. | Constraints perceived by the farmers for adoption of alternate wetting and drying AWD Technology in Puri district of Odisha India
