    Use of Salt-Tolerant Rice Varieties to counteract impacts of sea surges and saltwater intrusion, Philippines 2013

    There are 400 000 ha of coastal saline soils in the Philippines, of which 100 000 ha are in mangroves, 175 000 ha are in fishponds and 125 000 ha are idle. Due to changes in the climatic and other environmental factors / parameters, Bicol’s coastal region is undergoing and experiencing various changes in the cropping pattern. About 70 000 ha of rice production area in Bicol and Cagayan Valley are potentially affected by saline water intrusion, thereby needing special attention and improvement (PhilRice, 2001). Rice areas along the nipa palm in Rizal and Bagacay, are usually affected by saline intrusion. Farmers in these areas normally experienced low rice production, because the present rice varieties used are suitable for the increasing saline-stressed environment, especially during may (end of dry season) and in December. The wider dissemination of a selected salt tolerant variety, namely NSIC Rc-108, was tested in 3 pilot sites (Rizal and Bagacay, Gubat, Sorsogon) between June and October 2010 (wet season) in lowland irrigated farming systems in Bicol, the Philippines.

    Use of submergence rice variety NSIC Rc-194 to counteract impacts of flooding in the Bicol region, Philippines 2013
    Also available in:
    No results found.

    Rice is the staple food of Filipinos. Farmers experienced high risk of crop losses (40 to 80 percent) during the typhoon month of October, November and December. In Bicol Region, San Buena, Buhi, Camarines Sur crop lands get / remain flooded during parts of the months September and October after the harvesting. This challenging situation can be mitigated without need for investing in additional the land preparation and other inputs. The flood tolerant rice variety NSIC Rc-194 (IRRI) survives, grows, and develops even after 10 days of complete submergence at vegetative stage. The variety was tested in three pilot municipalities (San Buena, Buhi, Camarines Sur) between June to October 2010 (wet season) in lowland irrigated farming systems in the Philippines. The use of NSIC Rc-194 has enabled farmer cooperators to produce acceptable rice yield under above stagnant water conditions, during the second and third crop seasons.
