Farm practicing the System of Rice Intensification technology (Engr. Jemar G. Raquid (Bureau of Soils and Water Management))
The Organic-based system of rice intensification modifies the usual rice farming system in terms of seedling condition, planting distance, irrigation time and water requirement, and with the incorporation of organic fertilization scheme. Furthermore, integration of rice duck is carried out. This makes the farming system reduce its farm inputs leading to a lower production cost. With the utilization of organic fertilizers and natural concoctions, soil fertility and soil structure is improved. It was also observed that rice grown under SRI can tolerate strong winds. This type of rice production management is currently part of the Caritas Foundation’s project, a non-government organization, called Sustainable Learning Agricultural Farm which promotes diversified-integrated organic farming systems. With this, other practices (i.e. rice-duck farming) are being integrated in some SRI areas. Integration of ducks helps in the weeding since it eats weeds as well as harmful insects. In addition, its droplets/manure served as organic fertilizer in the rice field.
Purpose of the Technology: The purpose of this technology is to promote better soil management as well as more efficient water management.
Establishment / maintenance activities and inputs: Under SRI, the following practices were implemented: In the land preparation stage, 25cm x 25cm plant spacing is made using the man-made implement.
Intermittent irrigation is applied up to the panicle initiation stage with the following irrigation schedule: (1) 3 days after transplanting, (2) 9 days after transplanting, (3) 14 days after transplanting, and (4) 19 days after transplanting. The field is irrigated up to 5-cm water depth level per schedule.
Fertilizer application includes compost and natural organic concoctions. This is applied on different crop stages.
Natural / human environment: The existing project sites are located in Samar experiencing Type IV climate wherein rainfall is more or less evenly distributed throughout the year. Most of the farmer practitioners of this technology belongs to the small scale and average type of land user.
Location: Marabut, Samar, Philippines
