The effect of climate change in rice production is detrimental to our country's rice self-sufficiency. However, there are already technologies that can mitigate its effects. One is the use of direct seeding technology. Direct seeding has resulted to reduced methane emissions due to shorter flooding period and decreased soil disturbance compared to transplanted rice. Also, 60% of energy (diesel) is decreased because or elimination of field preparation for seedbed, pudding. DSR can also save 40% on labor cost required for seed bedding, pulling and transplanting. However despite these advantages, adoption remains low in Isabela. Thus, promotion of DSR through technology demonstration farms and trainings were conducted. In 2017 wet and dry seasons, demonstration farms established in Villafuerte and Daramuangan Norte, San Mateo, Isabela to showcase and localize the DSR technology. This project was conducted in collaboration with NIA-MARIIS and LGU-San Mateo. After which, selection and validation of demonstration sites, cooperators and participants for the conduct of season long farmers field school was done. To improve awareness on DSR, project briefing, ceremonial seeding and field days were also conducted in both sites. Based on the results, the demonstration sites in Villafuerte and Daramuangan Norte obtained yield of 5.7 and 6.7 t/ha with a net benefit of Php 48,985.00, and PhP 87,904.52, respectively. For 12 adopters with 6.43 hectares, yield obtained was 3.4 to 8.5 t/ha with net benefit ranging from PhP 33,685.00 to PhP 115, 468.00 per hectare during WS 2017. For DS 2018, another demonstration farm was established at Victoria, San Mateo, Isabela. There were 25 participants in the season-long farmers field school. At present, 26.47 hectares were planted using DSR for the 20 adopters. There should be a continuing promotional activity of DSR to further increase awareness of farmers within the municipality of San Mateo, Isabela.
