Rice-duck integrated farming system to improve farm productivity and increase farmers’ income in Maragondon, Cavite

To ensure the sustainable production and availability of food commodities during the onset of the pandemic, DA-BAR prioritized the outscaling of mature packages of technologies. One of which is the integrated rice-based farming systems implemented by the Research Division of DA-CALABARZON in Maragondon, Cavite. 

On 17 May 2022, DA-BAR visited the project site to monitor the progress of the research. The project team also presented their accomplishments and challenges encountered during its implementation. 

Fifty farmer cooperators benefitted from the two-year project, covering 50 hectares of rice areas. DA-CALABARZON trained them, along with six local government unit agricultural technicians, on rice and duck production technologies. Integrating duck raising into rice production not only provides additional income but also helps in controlling golden apple snail (GAS) and rice black bug (RBB) infestations. 

They introduced the use of inbred rice variety NSIC Rc216 on transplanting method in lowland irrigated condition. According to DA-Philippine Rice Research Institute (PhilRice), this variety when transplanted matures in 112 days and produces an average yield of six tons per hectare and a maximum of 9.70 t/ha.  Farmers claimed that vigorous performance of rice crop and increase in yield were attributed to the spraying of Vital N, an ameliorant/mitigant during seedling stage. 

They also enhanced farmers’ utilization of the Rice Crop Manager technology adopted from DA-PhilRice and the International Rice Research Institute, a decision support tool for site-specific crop and nutrient management recommendations, as well as PalayCheck System, a dynamic rice crop management system. 

To address the RBB infestation in the farmers’ rice crop, DA-CALABARZON researchers enlisted the help of the Regional Crop Protection Center (RCPC). They recommended applying Metarhizium on all farmer cooperators’ rice fields during the land irrigation and land preparation stage before planting schedule.  

For rice crop tolerance to diseases like rice blast and tungro, as well as nutrient deficiency, RCPC recommended using zinc supplement fertilizer in areas that exhibited yellowing of leaves and using Applaud insecticide to control green leafhoppers. 

To control GAS population, aside from grazing of ducks, DA-CALABARZON researchers advised the farmers to manually collect GAS on site, use bamboo sticks as traps during GAS egg laying period, and use forage or other plant material attractants. 

Further, five houses for the 550 genetically improved mallard ducks were established in the five farmers’ associations sites adjacent to the rice fields of the farmer cooperators. The farmers were also trained on incubator management and maintenance and value adding technology on duck eggs. The research team recommended processing of duck eggs into salted egg, balot, or penoy for additional income. 

A training on enterprise development and financial management will be conducted before the project ends to ensure the sustainability of the project. Two field days were also held to disseminate the introduced package of technologies to other farmers. Nine additional farmers adopted the technology during the course of the implementation.
