Engr. Flora Mae D. Respicio, principal engineer of M’lang/Malasila River Irrigation Systems (MLARIS), said controlled irrigation, a practical technique on saving irrigation water without decreasing yield, enabled farmers to share water supply with rice tillers owning farms in downstream.
In controlled irrigation, observation wells are used to monitor the status of water to help farmers determine the appropriate amount of water and timing of irrigation. Meanwhile, synchronous planting within one month is recommended to avoid the overlapping occurrence of pests and diseases.
“We used to implement 3-4-days irrigation interval but it caused conflicts among farmers because the water supply only reaches the mid-streams resulting in late planting or no planting in downstream. From this schedule, we shifted to 7-days irrigation interval,” she said in a field day recently conducted by PhilRice station based in Midsayap,
Respicio said LIDANAMA Irrigators` Association members initially had apprehensions following the new schedule as they are used to seeing their fields immersed with water.
“Through controlled irrigation, farmers are confident that nothing will happen to their rice plants after seven days of no water release. Now, the 1,660 ha of LIDANAMA Irrigators` Association were planted synchronously based on 2012 dry season cropping calendar,” she said.
About 175 rice farmers in the seven irrigators’ association covered by MLARIS had adopted controlled irrigation. With its adoption, Respicio said the National Irrigation Administration (NIA) in Region 12 will form core trainers who will implement the technology in a wider scale.
