Determining factors for the adoption of sprinkler irrigation system in Navithanveli Divisional Secretariat areas of Ampara district, Sri Lanka

摘要

Micro irrigation System (MIS) is promoted by the Government of Sri Lanka and NGOs in several vegetable cultivation areas of the Ampara district in order to increase the efficient usage of water. However, adoption of MIS especially sprinkler irrigation system (SIS) in these areas is very low and there is a potential to increase its adoption in these areas. In this view, this study was conducted in Navithanveli DS division areas of Ampara district to find out the factors influencing on the adoption of sprinkler irrigation for vegetable cultivation as an important tool to increase the adoption percentage of SIS. A field survey was conducted among randomly selected 126 vegetable farmers using structured questionnaires, direct observation and personal interviews. The study revealed that, the most important determinants of sprinkler irrigation adoption in the study area are level of education, age, profession, land holding size, availability of resources such as water, technology and capital, economic status of the farmer and level of awareness on MIS etc. These findings will help to prioritize the factors that affect MIS adoption decisions for improving the crop and water productivity in the study areas.
