The current climate change, combined with the increased demands from both traditional and new water users, including municipal, industrial, and agricultural sectors have impacted water resources. Thus, recycling of water as irrigation to secure seed production has a substantial impact on food security sustainability. In this research, a water recycling system was developed and tested to sustain the seed production. The research was conducted through eight seasons since 2014 to 2019 at the Rice Centre of Excellence (CoE) research plot in MARDI Seberang Perai. The system included the facilities to irrigate and collect water to be reused again. This approach was done to sustain the water resources as to ensure that the cultivation of paddy was not affected by weather changes. Rainfall and irrigation flow data were collected for the all of the seasons. Observation of field water depth was monitored every two days before irrigation was applied. This system proved that the total water saving for every season studied had a range from 20% to 32%, depending on the rainfall intensity. From this study, more than 3.5 t/ha of fragrance paddy seed were successfully produced for research and development purposes. |
