Participatory demonstration of Irrigation Scheduling on Wheat Yield and Water Productivity at Lintala Irrigation Scheme in Humbo District, Wolaita Zone South Ethiopia Region

The study aimed at participatory demonstration of irrigation scheduling and assess farmers’ preferences on wheat yield and water productivity in Fango-Lome Kebele Humbo District, Wolaita Zone South Ethiopia Region. The study indicates that irrigation scheduling technology significantly affects the grain yield of wheat and water productivity. The study revealed that the maximum grain yield (38.22Qt/ha) was acquired from the treatment level of (100%MAD) and minimum yield (30.22Qt/ha) was obtained from the farmers practices. The maximum value of water productivity (0.83kg/m3) was obtained in treatment level of 100% of MAD and minimum value (0.567kg/m3) obtained from farmers practices. Supplying fixed amount of water in fixed irrigation interval of five days in initial stage, seven days in development and mid stages and eight days interval in late stages can enhance grain yield of wheat and water productivity. Farmers were preferred irrigation scheduling technology by putting different criteria’s as best water saving technology and increases grain yield of wheat that ensures food security of livelihood. Therefore it should be recommended that the technology must be disseminated as the best finding to the neighboring farmers and irrigation schemes with the same agro ecology.
